Water is an essential resource for social and economic development. The availability of this constantly threatened by the rapid increase in its demand. This research assesses current (2010–2016), short- (2017–2040), middle- (2041–2070), long-term (2071–2099) levels water security considering socio-economic climate change scenarios using Evaluation Planning System (WEAP) Vilcanota-Urubamba (VUB)...

the main goal of this paper is to propose a new practical method for hydrologic soil group estimation in surface runoff process based on geomorphology facieses and slop. the determination of cn based on this method can reduce the time and cost of project. in this research the upstream rivers of glinak watershed have been used as a case study to examine the efficiency of proposed method with a c...

Abstract Hydrometric stations are important in most countries because of the application and importance data obtained from these stations. It is necessary to choose best place for their establishment according cost constructing hydrometric The aim innovation this research optimize location using Bat's meta-heuristic algorithm interpolation methods, which information transfer entropy theory were...

there are different materials and compounds in water that determine its chemical and physical quality. as the result of special conditions such as increase and decrease in discharge, water quality can vary. one of these conditions is drought that decreases discharge, and water quality changes. in this study, droughts of sistan and baluchistan province have been analyzed using standardized preci...
