as an assessment method of the water resources, water poverty index (wpi) has become an available tool in water resources management. in particular, agricultural water poverty index (awpi) is an assessment tool for agricultural water in rural areas. during the past decades, mahidasht basin in kermanshah province has been declared by water policy makers as “forbidden” basin in terms of water exp...

Water scarcity is a global issue, affecting in excess of four billion people. Interbasin Transfer (IBWT) an established method for increasing water supply by transferring from one catchment to another, water-scarce catchment. The implementation IBWT peaked the 1980s and was accompanied robust academic debate its impacts. A recent resurgence popularity IBWT, particularly promotion mega-scale sch...

Background: In recent times, the decreasing groundwater reserves due to over-consumption of water resources and the unprecedented reduction of precipitation, during the past 1 decades, have resulted in a change in the volume and quality of water with time. The aim of this study was to determine the spatial and temporal variations of hardness and total dissolved solids in drinking water resource...

The state of knowledge and outstanding challenges and opportunities in global water cycle observations, research and modeling are briefly reviewed to set the stage for the reasons behind the new thrusts promoted by the World Climate Research Programme (WCRP) as Grand Challenges to be addressed on a 5to 10-year time frame. Those focused on water are led by the GEWEX (Global Energy and Water Exch...

1. introduction the meaning of sustainability is an effort to reach the best results in human and environmental programs which are considered to be for present and future. zayandeh-rud is the most important and vital river in esfahan area which is used in agriculture, industry, providing drinking water and all other economic sectors. this river is originated from the zagros mountains – zardkooh...

Quantitative changes in groundwater and crises resulting from uncontrolled water extraction have turned water resources management into one of the supply-demand dilemmas in arid regions. The present study evaluated the quantitative situation of water resources in the Ardestan Plain adjoining the Ardestan desert by using the MODFLOW mathematical model. Simulation of groundwater flow in the stead...

Regional water supply systems undergo surplus and deficit conditions due to differences in inflow characteristics as well as due to their seasonal demand patterns. This study proposes a framework for regional water management by proposing an interbasin transfer (IBT) model that uses climate-informationbased inflow forecast for minimizing the deviations from the end-of-season target storage acro...
