In terms of having a comprehensive vision toward supplying the water requirements, multi-criteria decision-making approach was employed on Zarrine River Basin (ZRB) in northwest Iran. First, climate change impacts were analyzed with Long Ashton Research Station Weather Generator (LARS-WG) downscaling by using General Circulation Models (GCMs) including European Consortium Earth System Model (EC...

As climate change is projected to impose profound global variations in the freshwater resources, assessing the impacts of the former on the latter is a fundamental task for improving the water management, namely, in arid and semiarid areas, as there a plenty of in countries like Iran. Such is the objective of the present paper, where the impacts of climate change on the water availability in th...
