Evaluating the impact of climate change on water resources is necessary for improving water resource management and adaptation measures at the watershed level. This study evaluates the impact of climate change on streamflow in South Korea using downscaled climate change information based on the global climate model (GCM) and hydrological simulation program&ndash, FORTRAN model. Representative concentration pathway (RCP) scenarios 4.5 and 8.5 W/m2 were employed in this study. During the distant future (2071&ndash, 2099), the flow increased by 15.11% and 24.40% for RCP scenarios 4.5 and 8.5 W/m2, respectively. The flow is highly dependent on precipitation and evapotranspiration. Both precipitation and evapotranspiration increased, but the relative change of precipitation was greater than the relative change of evapotranspiration. For this reason, the flow would show a significant increase. Additionally, for RCP 8.5 W/m2, the variability of the flow according to the GCM also increased because the variability of precipitation increased. Moreover, for RCP 8.5 W/m2, the summer and autumn flow increased significantly, and the winter flow decreased in both scenarios. The variability in autumn and winter was so great that the occurrence of extreme flow could intensify further. These projections indicated the possibility of future flooding and drought in summer and winter. Regionally, the flow was expected to show a significant increase in the southeastern region. The findings presented for South Korea could be used as primary data in establishing national climate change adaptation measures.

In this paper a comparative risk assessment of the exploitation of old and new ash disposal sites in Kostolac is given. Risk assessment is carried out according to the FMEA (Failure Modes and Effects Analysis) method in combination with a risk matrix, which includes a detailed elaboration of potential accident scenario at disposal sites and analysis of consequences that accident can cause. As a potential accident scenario only hydrological scenario is taken into consideration, which is based on the influx of large amounts of precipitation, the cause of the largest number of accidents at industrial disposal sites. Analyses of environmental consequences, potential human losses and economic consequences are given. According to the risk matrix it is found that both of disposal sites are in the 'blue' zone of risk, which is interpreted as a tolerable level of risk, although the new disposal site is still in a better position than the old one because the expected level of risk is lower by one degree.

This research studies the change in land use in a binational hydrographic basin in South America. In addition, a future perspective for land use is generated according to the trends in the development observed. A multi-temporal analysis of land use change is carried out and variables that can explain the observed transitions will be selected. The relations between changes and explicative variables are studied in order to stochastically model future land use maps. Persistence was found to be the predominant state. Higher transitions were observed in the zones of boundaries between categories. Biophysical variables had the most explicative power with a better performance of the model based on logistic regression than the one made by using neural networks. © 2010 Elsevier B.V.

Despite the fact that there is no agreement among scientists about global warming, climate change, and their effects, there is no doubt that the availability of water resources depends to a great extent on climate. With the purpose of seeking evidence of climate change, the tendencies of the historical series of rainfall and temperature recorded in 40 climate stations located in the Ecuadorian-Peruvian border were studied by applying a fourth order moving average filter. After considering two different scenarios of climate evolution which were proposed by the IPCC, and applying 8 general circulation models, future regional scenarios of rainfall and temperature towards the year were generated toward the future years of 2025, 2050 and 2080. Evidence of climate change was found, and increasing trend of temperature, which is consistent with the volume of emissions of greenhouse gases. According to the scenarios analyzed, considerable climate disorders are forecasted with a steady increase in temperature and an oscillating decrease in rainfall., A pesar de que no hay consenso unánime entre la comunidad científica sobre el calentamiento global, el cambio climático y sus efectos, es innegable que el clima condiciona en gran medida la disponibilidad de los recursos hídricos. Buscando evidencias de un posible cambio climático, en el presente trabajo se estudian las tendencias de las series históricas de precipitación y temperatura registradas en 40 estaciones climáticas ubicadas en la región fronteriza ecuatoriano-peruana aplicando un filtro de medias móviles de cuarto orden. Considerando dos escenarios distintos de evolución climática propuestos por el IPCC y aplicando 8 modelos de circulación general se generaron escenarios regionales futuros de precipitación y temperatura hacia los años horizonte 2025, 2050 y 2080. Se encontraron evidencias de cambio climático, así como tendencias crecientes de la temperatura que son correspondientes al volumen de emisiones de gases de efecto invernadero. Según los escenarios analizados se prevé trastornos considerables del régimen climático actual con un sostenido incremento de temperaturas y una oscilante disminución de las precipitaciones. [fr] Bien qu’il y ait un consensus unanime parmi les scientifiques sur le réchauffement planétaire, du changement climatique et son impact est indéniable que le climat détermine largement la disponibilité des ressources en eau. Rechercher les preuves d’un éventuel changement climatique dans le présent document, nous étudions les tendances de la série historique des précipitations et des températures enregistrées à 40 stations météorologiques situées dans l’Equateur-Pérou dans la région frontalière en utilisant un filtre moyenne mobile du quatrième ordre. Considérant que deux scénarios différents de développement climatiques proposées par le GIEC et applicable 8 modèles de circulation générale ont été générés scénarios de précipitations régionale future et la température au cours des années 2025, 2050 et 2080. preuve du changement climatique a été trouvé, et l’augmentation de la tendances des température qui sont pertinents pour le volume des émissions de gaz à effet de serre. Selon les scénarios envisagés prévoit d’importantes perturbations dans le régime climatique actuel, avec une augmentation constante des températures et une diminution des précipitations.
