Urmia Lake in northwestern Iran has been facing critical water level shrinkage in recent years with serious environmental consequences. It is expected that with the current trend, the lake will be completely dried out in a few years from now. This study attempts to assess the impacts of human activities on water level fluctuations of Urmia Lake by developing a comprehensive hydrologic simul...
The reclaimed utilization of urban wastewater is an indispensable way for solving the crisis of urban water resource. In order to meet the needs of reclaimed water pollution control,the risk assessment model for reclaimed water utilization in basin are established. GIS was employed to derive all the data and evaluate model in order to get spatial variance and distribution of the risk levels on ...
The need for clean water has risen exponentially over the globe. Millions of people are affected daily by a lack of clean water, especially women and children, as much of their day is dedicated to collecting water. The global water crisis not only has severe medical implications, but social, political, and economic consequences as well. The Institute of Catholic Bioethics at Saint Joseph's Univ...
Recovery from the Flint Water Crisis has been hindered by uncertainty in both the water testing process and the causes of contamination. In this work, we develop an ensemble of predictive models to assess the risk of lead contamination in individual homes and neighborhoods. To train these models, we utilize a wide range of data sources, including voluntary residential water tests, historical re...
The relation between rainfall and water accumulated in reservoirs comprises nonlinear feedbacks. Here we show that they may generate alternative equilibrium regimes, one of high water-volume, the other of low water-volume. Reservoirs can be seen as socio-environmental systems at risk of regime shifts, characteristic of tipping point transitions. We analyze data from stored water, rainfall, and ...
recent droughts and indiscriminate use of ground water for agriculture, is the main problems of the especially desert country.water crisis has gripped all of country plains, and due tothe reduction of surface water resources and successive droughts, illegal exploitation of ground water resources is increasing.the knowledge of the water balance plains can be helped in the water resources managem...
When it comes to conflicts over the allocation of freshwater supply, who bears the burden, at what cost, and at what scale are important questions. While science can contribute to resolution of certain water allocation disputes, more scientific certainty will not resolve most water allocation controversies. Water stress in Africa and in theMiddle EastÑparticularly in theNile BasinÑis likely to ...
