Right Bank Outfall Drain (RBOD) is a drainage canal being built on the right side of river Indus, Sindh Pakistan and will carry saline water from Balochistan and Northern Sindh to Arabian Sea coast. It is still at different stages for completion. Thirteen samples were collected from RBOD III and RBOD I (Hairdin Pumping Stations, Balochistan to Sehwan, Manchar lake, Sindh), and a reference sample was collected from river Indus at Kotri Barrage. The sampling scheme was repeated three times in 2009 and 11 samples were collected from RBOD I during 2018. The water samples were analysed for about 27–41 different parameters, including physicochemical, cations, anions, trace metals and the presence of microbiological organisms. The variation in the water quality was examined pre- and post-monsoon season and flows of water at Kotri Barrage. A significant variation was observed in quality of water pre and post monsoon. Higher concentrations were reported during pre-monsoon season. The water quality index (WQI) indicated that most of the samples were within poor water category for both drinking and irrigation purposes. Gibb's diagrams demonstrated that evaporation was dominant (85.7%) on the hydrochemistry of the water samples. The Cd, Pb, Ni, Cr and As crossed the permissible limits at a number of sampling stations. The water samples were also examined for multivariate analysis including principal component analysis (PCA), cluster analysis, piper diagrams and coefficient of variation. Chloride (Cl−) and sodium were dominant, followed by calcium, magnesium, sulphate and bicarbonate. The average values of analyses (n = 4) indicated RSD within 4.0%. The samples were examined for possible use for irrigation and 53–92% samples collected from RBOD (n = 14) were within unsuitable category for irrigation. [ABSTRACT FROM AUTHOR]

Rapid and accurate judgment of the rock mass condition is the key to guaranteeing the safety and efficiency of tunnel boring machine (TBM) tunneling. This paper proposes a method for evaluating rock mass parameters based on K-means clustering, grouping tunneling areas according to the values of TBM tunneling parameters. A dataset including rock mass and TBM tunneling data is treated by logistic normalization and principal component analysis (PCA), and large volumes of tunneling data with different features are transformed into appropriate volumes of dimensionless data. K-means clustering is used, samples are grouped according to the values of tunneling data, and the specific ranges as defined by clustering are regarded as the unified evaluated results of each group. Based on the C1 part of the Pearl Delta water resources allocation project, 100 training samples and 30 testing samples were field-collected, and the proposed method was realized by the training samples and verified by the testing samples. The evaluation accuracies of uniaxial compressive strength (UCS), and joint frequency (Jf) were 90%, and 86.7% respectively, demonstrating that the evaluation had acceptable values, and the proposed method was greatly helpful for judging rock conditions.

Little information is available on the long-term changes of groundwater levels and their associated influencing factors. Zhangjiakou City was chosen as a case to reveal the temporal and spatial dynamics of groundwater level and its driving factors in the long term. Herein, the observation data of groundwater level from 56 wells was investigated from 1981 to 2015, including the collected meteorological data, socio-economic data, and groundwater resource exploitation situation. Results showed that the groundwater level in Zhangjiakou City tended to be decreased, and the decrease rate was gradually accelerated. In the past 35 years, the groundwater level of Bashang Plateau has decreased by 3.59 m < 3.6 m in Yuyang Basin < 7.17 m in Zhuohuai Basin < 20.41 m in Chaixuan Basin. The dynamic changes of groundwater level in four geomorphic units in Zhangjiakou City were significant correlation between the total population and other socio-economic factors, including primary industry production value; common cultivated land area; effective irrigation area; total grain yield; total vegetable yield; total production of pork, beef, and mutton; secondary industry production value; tertiary industry production value; and year-end total population. Furthermore, the principal component analysis of groundwater level variation in Zhangjiakou city showed that the variance contribution rates of the first principal component in the characteristic indicators of the Bashang Plateau, Chaixuan Basin, Zhuohuai Basin, and Yuyang Basin were 75.7%, 83.9%, 66.1%, and 77.8%, respectively, which mainly reflect the information of socio-economic factors. This indicated that socio-economic factors were the main driving factor influencing the continuous decline of groundwater levels in Zhangjiakou City. The obtained findings can provide new insights into the sustainable development of social economy and the rational utilization and allocation of regional water resources. [ABSTRACT FROM AUTHOR]

The public trust doctrine guarantees that the government will hold natural resources in trust and protect them for the common good. The doctrine has played a key role in the allocation of water rights, particularly for Native American and Native Hawaiian interests in the United States. State and federal courts often consider the doctrine when deciding if certain use rights should be granted. In Hawai'i, the doctrine has taken on a particularly robust form because the State Constitution expressly provides that all public natural resources are to be held in trust for the benefit of all Hawaiians. Unfortunately, the doctrine's application has not always benefited Native Hawaiian interests. This Comment analyzes the current status of the public trust doctrine in Hawai'i and its unique relation to Native Hawaiian rights. Because the State has historically prioritized large sugar plantations on the islands over its Native population, modern applications of the doctrine to protect the islands' natural resources are a relatively new concept in Hawaiian law. By evaluating statutes and cases from the Kingdom of Hawai'i (1795-1893); the Territory of Hawai'i (1900-1959); and the current State of Hawai'i (1959-present), this Comment builds a more complete picture of Hawaiian jurisprudence around natural resource allocation and explores ways to reinterpret the public trust doctrine. One of the purposes of the doctrine has been to protect Native Hawaiian water rights and to uphold the exercise of Native Hawaiian traditions and customs, yet the State has yet to live up to that purpose. The State Legislature should enact laws that require consultation with Native cultural organizations when a state agency issues any permit in land, water, or other natural resource or when any court reviews the allocation and use of any natural resource.

A socio-hydrological model that simulates, couples and co-evolves reservoir operation and human behaviour to assess the impact of unauthorized water abstractions on reservoir performance is developed. The model relates hydrological state, well-being, user compliance and management competence and is applied to two reservoirs. To generalize the modelling, well-being, user compliance and management competence are normalized (0 to 1) and modelled using logistic functions. When compliance is below the set threshold, unauthorized water abstraction occurs; the magnitude depends on water allocation, user compliance and management competence. In the absence of real data, eight hypothetical scenarios are applied. The expected dependence of well-being on the hydrological state and that of well-being, virtues and management competence on user risk perception and user compliance was realized as initially hypothesized. The variation of the effect of human factors on storage and yield was found to be more pronounced during low hydrological states (drought). The modelling is considered applicable for assessing the likely impact of humans on real reservoir performance. [ABSTRACT FROM AUTHOR]

What conditions gave rise to the Flint Water Crisis? Students of contemporary urban disasters tend to advance two claims, increasingly in tandem. First, preexisting racial and class inequalities structure both the impact of disasters on urban communities and the dynamics of resettlement. Second and similarly, neoliberalism (variously theorized as neoliberal urbanism and the growth machine) prefigures urban disasters and underpins an ensuing market-oriented process of redevelopment. While long-standing patterns of inequality and neoliberalization are important contextual factors, by themselves they tend to undertheorize the timing and ecological content of urban crises. In this article, we synthesize the literature on uneven development, urban political ecology, and racial capitalism to advance an alternative hypothesis. Drawing on interviews with Flint residents and Michigan officials, the archival correspondence of government agencies, and ethnographic data, we argue that the Flint Water Crisis was the consequence of an extractivist project of White state and suburban actors to "regionalize" and thereby expropriate the assets and natural resources controlled by the predominantly Black working-class city of Detroit. Specifically, the formation of two regional water authorities required that Flint leave the Detroit Water and Sewer Department for an interim water source, the Flint River, which had been contaminated by decades of automotive toxins.

Precipitation unevenness significantly influences the rational allocation of water resources and the management of agricultural irrigation. Based on precipitation data from 29 meteorological stations in Heilongjiang Province, China, from 1961 to 2020, this study calculated the precipitation concentration index (PCI), precipitation concentration degree (PCD), and precipitation concentration period (PCP) to analyze the spatial distribution characteristics of precipitation heterogeneity at three distinct timescales: year, maize growth period, and the four stages of the maize growth period. The findings reveal that the rainy season in Heilongjiang Province commences earlier in the southwest compared with the northeast and northwest, with a primary concentration in July. At the annual scale, PCI in southwestern Heilongjiang Province surpasses that in the southeastern region, displaying an approximate east–west gradient in PCD and PCP values ranging from 0.544 to 0.746 and 196 to 203, respectively. During the growth period scale, precipitation concentrates in the southwest and central regions, occurring earlier than in the northeast and northwest. In contrast to the annual scale, the PCI value is smaller, and precipitation predominantly concentrates in mid and late July. Examining the four stages of the maize growth period, PCD generally exhibits a decreasing gradient from west to east. The highest values of PCI and PCD manifest in the southwestern part of Heilongjiang Province, with precipitation concentrated in the middle of each growth stage. The research results serve as a valuable reference for policymakers and stakeholders involved in water resource allocation and agricultural water management in Heilongjiang Province.

This article explores the relationship between climate destabilization, neoliberalism, and the water crisis in Chile. It discusses how climate disruption, particularly drought, has contributed to a sociopolitical crisis in the country. The article also examines the historical context of water governance in Chile, specifically the introduction of neoliberal policies in the 1980s, and how these policies have shaped the current water crisis. The issue of water has become a source of political struggle and conflict in Chile, impacting various sectors of society. The article highlights the significance of the events in October 2019, which marked a crisis of legitimacy for the neoliberal state and led to the emergence of new social and political movements. Water is also seen as a key issue in the broader critique of neoliberalism, connecting to conflicts related to energy infrastructure, Indigenous relations, and territorial governance. The failure of the constitutional process in Chile has further deepened the crisis of political legitimacy and representation. The article emphasizes the complex dynamics between the climate crisis and the water cycle, as well as the issues surrounding extraction and water scarcity. It suggests that amidst this historical crisis, an "adaptation regime" is being developed in Chile, and understanding this moment requires attention to the emerging subjects, values, and forces.

This article aims to highlight the expertise of First Nations women in water management and use, and the necessity of having their voices heard in this space, as their voices have not received the attention or respect, yindyamarra, they deserve in Australian water law and policy. Before critically examining the articulation of a right to water in the international human rights framework as it applies to First Nations women, this article opens by introducing the nature and importance of First Nations women’s water rights. The article then turns to Australia, outlining the emergence of First Nations rights generally, before turning its attention to water rights. In that respect, Commonwealth law and policy is analysed, given that it is the nation-state with legal personality in international law. Two contrasting case studies follow, illustrating the importance and fragility of First Nations women’s water rights. The article concludes that international law evidences a deficit discourse, providing little basis for nationstates to recognise the holistic nature of water rights of First Nations women, and that Commonwealth law and policy, although showing promising signs, has yet to provide any meaningful scope for First Nations women to use and manage water according to First Nations law.

Context: Contemporary resource management paradigms within the developed world build on an understanding of human agency as ontologically distinct from the mode of existence of plants and animals. Because of this perspective, which gives priority to human agency, policies typically take their point of departure with human societies and associated ecosystems deemed of particular value. Objectives: As an alternative to this worldview, social theorists have introduced what is known as "flat ontology", where all beings are bestowed equal rights to negotiate their existence. To explore the implications of introducing such an understanding into landscape management, a participatory planning process for water allocation was developed and tested in a case study in the Eerste River Catchment in South Africa. Methods: The planning process was mediated using the approach "politics of nature" (PoN), which aims to operationalize flat ontology to renegotiate water allocation based on the needs of all beings instead of the desire of a subset of humans. PoN allowed participants to playfully co-develop a common ontology and value-set. Data documenting these processes were collected digitally and analysed. Results: Results indicate that the approach engendered a rethinking of key relationships between human agency and ecosystem functionality, illustrating a potential for PoN-approaches to be deployed for governance of complex landscapes. Conclusions: On the basis of experiments using PoN-methodology in the context of watershed management, it is discussed how the introduction of a flat ontology in landscape research, could inspire new ways of designing and intervening with collaborative resource management processes.

Water governance determines "who gets water, when, and how" in most large river basins. Shifts in water governance regimes from natural to social‐ecological or "hydrosocial" carry profound implications for human wellbeing; identifying regime changes in water governance is critical to navigating social‐ecological transitions and guiding sustainability. We characterized water governance along with the three main aspects—stress, purpose, and allocation—to develop a quantitative integrated water governance index (IWGI) at a basin scale. Applying the IWGI to the rapidly changing Yellow River Basin (YRB) in China clarifies shifts in water governance between massive supply, transformation governance, and adaptation‐oriented regimes. In the YRB, the underlying causes of regime shifts were increasing water supply and demand before the governance transformation and re‐allocation and regulation after the change. The IWGI offers a comprehensive and straightforward approach to linking water governance regimes to sustainability, providing valuable insights into hydrosocial transitions. Plain Language Summary: Missing governance means missing sustainability. However, the lack of a comprehensive but straightforward approach to identifying the changes in water governance presents a challenge for efforts to underpin it. Therefore, we choose indicators for the corresponding aspects (water stress, water services purpose, and water allocation) and combine them into an integrated water governance index to analyze long‐term changes in a large river basin. Key Points: An integrated water governance index was devised to identify regime shifts in water governance practicesThe study interprets the transformation of water governance within a rapidly evolving large river basin—the Yellow River BasinA novel approach was developed to analyze interconnections between water governance, hydrosocial transition, and human‐water relationships [ABSTRACT FROM AUTHOR]

This research study was conducted in three districts i.e. District Malakand, District Charsadda, and District Mardan in central Khyber Pakhtunkhwa to assess farmer's satisfaction and awareness about irrigation water rights. For this purpose, multi stage stratified random sampling techniques was used for the randomly selection of 466 farmers. This study sheds light on the critical dimension of water rights awareness among farmers and its profound impact on irrigation practices. The research highlights a concerning lack of awareness regarding water redistribution following land transactions, as well as the fundamental understanding that water ownership is tied to the land itself, rather than the proprietor. This study also examines the relationship between farmers' awareness of water rights and their satisfaction with irrigation water distribution, taking into account different age groups. Results indicate a positive and statistically significant association between water rights awareness and satisfaction for young adults (20-40 years, Tc = 0.101, P = 0.023), middle-aged adults (41-60 years, Tc = 0.303, P = 0.000), and older adults (above 60 years, Tc = 0.269, P = 0.007). Overall, the study reveals a highly significant and positive correlation (P = 0.000, Tc = 0.59) between water rights awareness and farmer satisfaction with irrigation water distribution. Age emerges as a key factor influencing this association, with middleaged farmers exhibiting notably higher satisfaction due to their heightened awareness of water rights compared to their younger and older counterparts. The study recommended critical insights for policymakers and stakeholders to improve water distribution systems and promote equitable access to this vital resource. [ABSTRACT FROM AUTHOR]

In the ecological protection zone, it is unclear how the joint development of urban agglomeration affects the supply–demand of water‐related ecosystem services (ESs). This study took northwest Hubei, China (Exibei), a national ecological function area, as a case study and predicted the land‐cover distribution in 2040 under three scenarios: natural scenario (2040NS), economic development (2040ED) and ecological protection (2040EP). And the supply–demand risks of water‐related ESs were simulated under three scenarios. Results indicated that (1) the increase in forest land (0.70%) under 2040NS, construction land (50.03%) under 2040ED and water body (15.16%) under 2040EP basically happened through the occupation of cultivated land; (2) under three scenarios, although the water yield demand in 2040 increased significantly, the supply still fully meet demand; (3) from 2020 to 2040, more than 13.50% of the areas in Exibei of water yield changed from surplus to deficit, mainly covering the north Xiangyang City and the middle Shiyan City; and (4) the change in supply and demand of soil retention from 2020 to 2040 was not obvious. This study provides assistance in water resources rational allocation in ecological function zones with rapid economic development and urban expansion. [ABSTRACT FROM AUTHOR]

Trans-boundary water conflicts and the ensuing social security have become concerning issues. However, the existing studies regarding trans-boundary water management mainly focus on river basin countries while ignoring the important role of third-party mediation institutions in resolving water conflicts. Thus, river basin countries and third-party mediation institutions are the objects of this research, which focuses on the strategies and behavior of third-party mediation institutions that are significant in alleviating conflict situations and formulating sustainable trans-boundary water resource allocation plans. The factors that influence the decision-making of third-party mediation institutions are determined based on other decision makers' (DMs') known preferences. Therefore, according to the uncertainty theory and the cognitive preference model, a novel inverse problem model of the graph model for conflict resolution is constructed to obtain the required DM preference information in complex and uncertain conflicts. Then, the new proposed method is applied to trans-boundary water conflicts in the Lancang-Mekong River Basin to illustrate its correctness and practicality. The results show that (1) a third-party management institution can directly promote a win–win situation among all DMs by obtaining other DMs' preferences; (2) effective supervision by a third party can promote all those involved to reach a stable state faster; and (3) third parties can promote sustainable trans-boundary water resource allocation. The proposed methods and analysis results offer decision-making support for third-party management institutions in trans-boundary water resource conflicts and provide a scientific basis for mediating similar water resource conflicts within and beyond China.

Egypt, Sudan and Ethiopia possess diverse natural resources and a substantial labor force that permit forming a successful trade integration. However, the recent dispute over the Grand Ethiopian Renaissance Dam (GERD) project between Ethiopia and downstream countries, Egypt and Sudan, has weakened the bilateral relations and disrupted trade flows among the three countries. This paper investigates the pattern of trilateral trade between Egypt, Sudan and Ethiopia during the period between 1995 and 2018. The study also examines the prospects and challenges for establishing a trilateral trade integration between the three countries. The study adopted the gravity model approach, along with the export diversification and trade complementarity indices, in order to scrutinize the pattern and structure of trade between the countries under study. The analysis indicated that Egypt is the most diversified economy with many crucial comparative advantages, which may grant it a leader position in the integration. Moreover, the paper revealed many challenges that may hinder the implementation of trilateral trade integration including, export concentration, poor infrastructure and disputes over water resources. Finally, the paper recommends that facilitating bilateral trade among the riparian countries of Eastern Nile Basin would mitigate the complex clashes over water rights. [ABSTRACT FROM AUTHOR]

Integrated solutions to groundwater management problems require effective analysis of stream-aquifer connections, especially in irrigated semi-arid regions where groundwater pumping affects return flows and causes streamflow depletion. Scientific research can explain technical issues, but legal and management solutions are difficult due to the complexities of hydrogeology, the expense of data collection and model studies, and the inclination of water users not to trust experts, regulatory authorities, and in some cases, their management organizations. The technical, legal, and management issues are reviewed, and experiences with integrated management of stream-aquifer systems are used to illustrate how governance authorities can approach engineering, legal, regulatory, and management challenges incrementally. The situations in three basins of the State of Colorado with over-appropriated water resources are explained to identify modeling and control issues confronting regulators and managers of water rights. Water rights administration in the state follows the strict appropriation method and a workable technical-legal approach to establishing regulatory and management strategies has been developed. The explanations show how models and data management are improving, but the complexities of hydrogeology and institutional systems must be confronted on a case-by-case basis. Stream-aquifer systems will require more attention in the future, better data will be needed, model developers must prove superiority over simpler methods, and organizational arrangements will be needed to facilitate successful collective action amidst inevitable legal challenges. Continued joint research between technical, legal, and management communities will also be needed. [ABSTRACT FROM AUTHOR]

A reasonable allocation can improve the allocation rate of water resources, and ensure ecological coordination and promote economic development. However, with cities developing quickly, urban water resources allocation is becoming more and more prominent. This study designs a multi-objective optimal allocation model of urban water resources based on simulated annealing algorithm, introduces the sudden jump of probability, adopts the multi-objective Pareto effective solution, and further improves the simulated annealing algorithm. The actual total water demand in 2022 is 6,606.53 million·m3 larger than the actual water supply 6,556.53 million·m3. The small probability errors of water demand and water supply forecasts are 0.8532 and 0.9586, the average relative errors are 0.0231 and 0.0212, and the variance ratios are 0.2125 and 0.2109, indicating that the forecasts are valid and the prediction accuracy is good. The model convergence is the fastest when using the multi-objective simulated annealing algorithm to close compared with other algorithms. By using an improved simulated annealing method to solve this multi-objective optimal allocation model effectively avoids the iterative process from falling into local optimum and improves the accuracy of prediction evaluation. The experimental results show that the algorithm has high accuracy and stability for water resources optimal allocation, which has certain practical significance and economic value in water resources.

Sound water resource management is critical for Ethiopia to protect water bodies and wetlands as well as tap these resources for better socio-economic development. However, water resource management has faced challenges in Ethiopia. This article examines whether water resources could be better managed through an innovative way of integrating their management and administration with land administration in line with the principle of Integrated Water Resource Management and sustainable land management. Doctrinal analysis of laws pertaining to water and land management is applied to this end. Primary data collection methods were also applied through questionnaire survey, in-depth interview, and focus group discussion. The article discusses the general role of sustainable water resource management in the protection of the country's water bodies and examines the critical gaps under the present fragmented natural resource management system. A conceptual framework is developed to highlight the relationship between the principle of sustainable water resource management and land management. The existing natural resource management in Ethiopia is unsustainable and hence it is argued that a land administration approach can enhance water resource management in an integrated, holistic, and sustainable fashion by focusing on Lake Tana Watershed.

The Constitution of the Republic of South Africa considers access to water a basic right for all citizens, and it assigns the responsibility of water provision to municipalities. Nevertheless, water access is not yet available to all citizens, for several reasons. South Africa is the thirtieth-driest country worldwide and has severe water-infrastructure backlogs from insufficient funding and investment. Public-private partnerships (PPPs) may be utilized to bridge the funding gap; however, they are rarely used as a financing option, so this study assesses factors influencing their adoption for water-infrastructure projects. The findings show that a cumbersome regulatory environment, political influence, PPPs' complexity, and the lack of knowledge and skills influence adoption of them by municipalities., Introduction Water is essential to sustain life, and access to and competition for it pose a potentially serious threat at a global level (World Economic Forum 2015, 8). Addressing access [...]

Unconventional water includes reclaimed water, harvested rainwater, desalinated seawater, and mine water. Unconventional water use is considered more of a “mandatory responsibility” in China. The initial allocation of unconventional water emphasizes quantity-centered responsibility allocation while the minimum utilization reflects this responsibility. The unconventional water use responsibility (UWUR) should be tailored to the characteristics of each area, moving away from a ‘more is better’ mindset. However, there is a large research gap in this field. This paper first presented six fundamental principles for unconventional water allocation. Ensuring fairness in allocation involves aligning the allocated amount with urban water usage characteristics. Hence, based on four key features, this paper integrated various socioeconomic and environmental factors to build an initial allocation model. To enhance efficiency, an optimal allocation model was constructed using the zero-sum gains–data envelopment analysis (ZSG-DEA) method. The models were then applied to Jiangsu Province, China, to verify their applicability. The results showed that the projected minimum UWUR allocation (unit: 100 million m3) for each city in 2025 is 1.482 (Nanjing), 1.501 (Wuxi), 0.919 (Xuzhou), 1.029 (Changzhou), 2.977 (Suzhou), 1.497 (Nantong), 0.818 (Lianyungang), 0.766 (Huai’an), 0.875 (Yancheng), 0.920 (Yangzhou), 0.790 (Zhenjiang), 0.858 (Taizhou), and 0.766 (Suqian). The rational and feasible results indicated that the allocation framework proposed in this paper has a certain practicability. Lastly, this paper considered the differences in unconventional water utilization conditions across 13 cities and proposed corresponding measures to improve the utilization. This paper represents a tentative exploration of unconventional water allocation in China and offers theoretical and practical insights for policy-makers to improve territorial spatial planning and sustainable water management.

The low-carbon design of wetland park landscape is very important to maintain the water balance and carbon balance of human and ecosystem. The combination of an increase in carbon emissions and a decrease in carbon capture increases net carbon emissions. Based on the coupling and coordination analysis between water ecological construction and carbon emission of urban park wetland ecological landscape, this study constructed a carbon-water (CW) coupling simulation model of urban park wetland ecological landscape, proposed a low-carbon urban park wetland water ecological model, and then analyzed the coupling effect of carbon and water and carbon emission prediction of urban park wetland. The above method is supported by the recognition technology of CW coupling mechanism of urban park wetland and the reasonable allocation technology of water resources based on low-carbon model, and the technical innovation is realized in these two aspects. Finally, the low-carbon water resource allocation plan of urban park wetland is discussed. The results show that economic development and energy consumption will be developed according to the extended or low-carbon model, and the agricultural and forestry irrigation quota will be reduced by 0.01~0.02 mm and 10,000 m3 / ha, respectively. The irrigation water utilization coefficient, the water consumption rate of canal system and channel system were increased to 0.74 and 0.85 respectively. The technological innovation and results of this study provide new ideas and methods for low-carbon landscape design and water resource management of wetland landscape ecology. [ABSTRACT FROM AUTHOR]
