Due to the influence of environment and other factors, there are often abnormal data in dam monitoring data and the detection of abnormal data plays an indispensable role in the normal operation of the dam. However, the accuracy of traditional anomaly detection algorithms for dam monitoring data often fails to meet the requirements. In this paper, an anomaly detection algorithm based on Prophet GMM was proposed. The better fitting performance of Prophet algorithm was used to fit the dam data and the residual sequence was obtained from the fitting data and the actual data. Then, the residual sequence was clustered by GMM algorithm to accurately identify the abnormal value. The test results show that the method proposed in this paper can accurately identify outliers for different types of dam monitoring data. Compared with the traditional detection algorithm, it has significantly improved the detection indicators of precision, recall and accuracy. [ABSTRACT FROM AUTHOR]

In order to solve the problem that the assessment method of urban water resources vulnerability too subjective and not taking into account the finite rationality of natural person and the psychological behavior characteristics of regret avoidance, which resulting in the distortion of the evaluation results, this paper proposed an urban water resources vulnerability assessment method based on OWA operator empowerment and regret theory. The DPSIR model was used to construct 29 evaluation indexes from the following five aspects including driving force, pressure, state, influence and response. OWA operator was used to reorder the decision data, which fully considered the location and size of data, so as to weaken the negative effect of extreme decision data on weight. The difference between the utility value of decision data and the ideal utility value in the regret theory was selected as the basis to evaluate the subjectivity of experts, so as to realize the objectification of the subjective data of decision making and improve the objectivity of the evaluation results. Finally, this paper evaluated the water resources vulnerability of Zhengzhou from 2017 to 2022, and compared the evaluation results with those of AHP and regret theory, OWA operator and fuzzy mathematics. The results show that the evaluation results of urban water resources vulnerability assessment method based on OWA operator empowerment and regret theory are basically consistent with the evaluation results of other methods, all of which are considered as severely vulnerable water resources in Zhengzhou City. However, the evaluation results of this method have less relative error and are more close to the actual situation, which can be better used for the assessment of urban water resources vulnerability.

Aqueduct is a typical space thin-walled structure, which is very sensitive to external temperature changes. Surface insulation measures can effectively improve the temperature stress distribution of the structure and prevent surface cracks. Although the calculation method of surface insulation capacity commonly used in dam construction is of reference significance to aqueduct insulation issue, it cannot be directly applied, so the aqueduct insulation issue needs to be studied separately. Therefore, based on the temperature load of aqueduct structure, this paper put forward a calculation method of aqueduct insulation design based on the temperature and temperature stress analysis of concrete structure. The calculation results show that the stress state of the groove body can be greatly improved by laying 5.0 cm thick polyurethane foam insulation material on the outer surface of the straight wall section and the arc section of 0°-45°. When the temperature rises, the inner wall circumferential and longitudinal tensile stress does not appear. When the temperature drops, the circumferential and longitudinal stress of the outer wall is reduced, and the stress state of the inner and outer walls of the groove body meets the design requirements. The project case study shows that the calculation method of thermal insulation design proposed in this paper can be applied to the thermal insulation design of aqueduct during operation, and then the key parameters of thermal insulation design such as laying range and insulation layer thickness can be determined.

The water quality data of the river basin has dual dependencies in time and space. Based on the fact that most of the existing water quality prediction models are only based on the time dimension and cannot make effective use of the spatial correlation of water quality, a spatiotemporal prediction model based on graph convolution neural network GCN and long short-term memory network LSTM was proposed in this paper. Firstly, the whole watershed was constructed into the topology of station-to-station connection, and the distance along the river between stations was taken as the indicator of connectivity between stations. For each input time, an independent GCN was used to capture the spatial relationship between stations, and then the temporal variation characteristics were captured by LSTM. Finally, the multi-step prediction results were obtained by multi-layer perceptron (MLP). The south source of Qiantang River was selected as the research object, multi step prediction experiments were carried out on three water quality prediction tasks of pH, DO and CODMn at 15 monitoring stations in the basin. The results show that in the three water quality prediction tasks, the average percentage error MAPE of GCN-LSTM model compared with LSTM model is decreased by 15.29%, 11.77% and 9.8% respectively. Compared with some classical time series models, the model proposed in this paper can better capture the spatial relationship of watershed water quality, improve the accuracy of water quality prediction and provide a new method for watershed water environment quality prediction. The connections between monitoring points have differences, and using distance to represent the strength of the connections between monitoring points can make water quality prediction results more accurate.

In order to fully explore and realize the value of soil and water conservation carbon sink in the Yellow River Basin, and effectively promote its development and market trading, on the basis of clarifying the connotation and characteristics of soil and water conservation car- bon sink in the Yellow River Basin, its quality was evaluated from three dimensions; the contribution quality of new carbon storage, the contribution quality of sustainable development, and the quality of carbon sink production process. This paper built an evaluation index system composed of 3 first-level indicators, 14 second-level indicators and 47 third-level indicators, and pointed out the appropriate methods for determining the weights of indicators at all levels and the methods for calculating the carbon sink quality index of soil and water conservation. It suggests that: firstly, we should carry out a whole process pilot project in the Yellow River Basin including high-quality soil and water conservation carbon sink development, monitoring and accounting, carbon sink project rating, information disclosure, and market trading; secondly, we should strengthen international cooperation and exchanges, learn from the differentiated pricing mechanism of the international voluntary emission reduction market, and build a carbon sink pricing system for soil and water conservation in the Yellow River Basin.

The security of agricultural water resources is crucial for food security, ecological environment and the economic development of rural areas. In order to promote efficient utilization and sustainable development of regional agricultural water resources, taking into account the impact of uncertainties and complexities, this paper adopted methods such as ordinal relation analysis, entropy weight method, and TOP- SIS (Technique for Order Preference by Similarity to Ideal Solution) to select 11 typical indicators across three subsystems of water resources, ecology and agricultural water use to build an evaluation index system. This system was used to assess the agricultural water resources security status in 14 prefecture-level cities within the Yellow River water diversion area of Henan Province in 2022. The results show that among the 14 prefecture-level cities, except Kaifeng is the "unsafe" level and Xinxiang, Hebi, and Puyang are the "generally safe" level, the other 10 cities are the "relatively safe" level, which still has some distance away from the "safe" level. It recommends to implement measures such as improving water quality, increasing available water resources, adjusting crop planting structures, enhancing water resources utilization efficiency, and enforcing the strictest water resources management system to ensure the agricultural water resources security in the Yellow River water diversion area of Henan Province.

In order to solve the issue of water scarcity in coal mining areas, this paper collected hydro-geological data from 18 typical coal mines from six major coal mining areas of Hebi, Jiaozuo, Yongcheng, Pingdingshan, Yima and Zhengzhou in Henan Province and evaluated the utilization of groundwater resources in coal mine goaf areas, by using the AHP-set pair analysis to construct an evaluation index system. with utilization of groundwater resources in typical coal mine goafs in Henan Province as the target layer; water quantity, water quality and current status of water resources utilization in mining areas were taken as the criterion layer; twelve evaluation indicators, including mine water inflow, average coal thickness, goaf area, maximum mining depth, roof lithology, complexity of geological structure, total hardness, total dissolved solids content, pH value, chloride ion content, mine water utilization rate and incentive policies were taken as the index layer. At the same time, it also evaluated the utilization of groundwater resources in coal goafs in Henan Province and compared the results with those obtained from analytic hierarchy process. The results show that the evaluation results of the two methods are basically consistent. The utilization feasibility of groundwater resources in typical goaf of six coal mining areas in Henan Province is the best in Jiaozuo mining area, the worst in Yongcheng mining area, and the other four mining areas are in the middle and the evaluation results are similar, indicating that the evaluation index system and evaluation results of typical goaf groundwater resources in Henan Province built by AHP-set analysis method are relatively reliable.

In order to promote the green, low-carbon and high-quality development of agriculture, this paper adopted the super-efficiency SBM model and the entropy method to measure the agricultural carbon emission efficiency and the high-quality development level of agriculture in the Yellow River Basin, and discussed the interaction between the two by using VAR model. The results show that a) the agricultural carbon emission efficiency in the Yellow River Basin is on the rise as a whole. The agricultural carbon emission efficiency of Gansu and Shanxi, Sichuan, Shandong, Henan, Shaanxi and Qinghai, Ningxia and Inner Mongolia is at a lower, medium and higher level respectively. b) The overall level of high-quality agricultural development shows a fluctuating upward trend. Shaanxi, Shanxi, Ningxia and Inner Mongolia, Qinghai and Gansu, Henan, Sichuan and Shandong are at a lower, medium and higher level respectively. c) The improvement of agricultural carbon emission efficiency has a significant effect on the promotion of high-quality agricultural development, while the improvement of high-quality agricultural development has no significant effect on agricultural carbon emission efficiency. Based on the research results, some suggestions were put forward to improve the efficiency of agricultural carbon emissions and promote the high-quality development of agriculture in the Yellow River Basin from the aspects of green and sustainable development.

Clarifying the relationship between hydrological connectivity and flood probability is an important basis for scientific development of flood management measures. In this paper, the hydrologic connectivity index (RIC) of the Kuye River (KYH) catchment was measured by using a modified hydrologic connectivity model based on hydrologic observations and remote sensing data. Advanced spatial analysis tools and statistical tests, including the Theil-Sen Median and Mann-Kendall methods, were employed to analyze the spatial-temporal evolution patterns of RIC. An ordered logistic regression model was then used to examine the influence of RIC on flood probability. The results indicate a significant decline in the yearly average RIC value. Significant reductions in RIC are primarily observed in specific regions. Spatially, RIC concentrations with high-high agglomeration are in the downstream rock mountainous areas of KYH. Notably, low-low aggregation is found in the Ulan Mulun River catchment, particularly in the Kangbashi and Yijinhuoluo. The trend of long-term significance change is dominated by highly significant decrease and significant decrease. Floods in KYH are mainly concentrated in the summer, with their frequency and annual maximum instantaneous streamflow (AMS) showing a significant downward trend. The mutation point of AMS is found to be in 1998 by the Mann-Kendall test in KYH. The RIC significantly contributes to the probability of flood occurrence. Specifically, when all other variables are fixed and unchanged, for each unit increase in the RIC, the probability of a flood becoming a larger magnitude increases by 5.999 times.

Accurately predicting the flood peak discharge increase phenomenon in the Yellow River during the period of water and sediment regulation is not only an urgent need for reservoir dispatch and flood control, but also a new topic for hydraulics and river dynamics research. This paper took the value-added ratio as the dependent variable, the sediment concentration peak, the average rate of increase during the peak period of the sediment concentration, the base flow before the sediment concentration rises, the particle size of suspended sediment at Xiaolangdi Station as the independent variables and the correlation analysis was conducted. As a result, the sediment concentration peak at Xiaolangdi Station and the average rate of increase during the peak period of the sediment concentration are filtered out, as the prediction parameters for the flood peak discharge increase. The study proposes that the flood peak discharge increase phenomenon may occur in the Lower Yellow River when the average increase rate during the peak period of the sediment concentration at Xiaolangdi Station exceeds 22.9 kg/m³h, and the value-added interval can be predicted on the basis of the correlation between the peak sediment concentration and the value-added ratio of flood peak discharge. By tracking the real-time water and sediment conditions at Xiaolangdi Station during the water and sediment regulation in 2023, prediction and forecasting of the flood peak discharge increase phenomenon was carried out, the prediction results are basically consistent with the measured results.

As the mother river of China, the Yellow River Basin serves as a crucial ecological domain and economic zone, as well as a vital source of food and energy. It plays an indispensable role in the political, economic, and cultural development of the nation. The ecological protection and high-quality development of the Yellow River Basin have become a major national strategy in China. Yet, the Yellow River is among the most complex and challenging rivers in the world. Throughout China's long history, especially since efforts began to regulate the river, significant achievements have been made in its management and ecological protection. However, many critical issues still need to be addressed. This paper explored the rich history of the Yellow River Basin management and successes, examined the current situation and challenges, and provided recommendations and strategies for achieving long-term stability, sustainability, and high-quality development in the Yellow River Basin, such as constructing the water resources security system of the basin, realizing the restoration and protection of the ecological environment in the key areas in the basin, and improving the engineering system of flood control, ice-flood prevention and water-sediment regulation in the basin, etc. [ABSTRACT FROM AUTHOR]
