Effects of a chain of reservoirs on temporal and spatial variation in water chemistry within an endorheic basin

Reservoirs provide more than 90% of water for agricultural, municipal, and environmental flows in arid regions. Yet, these resources may be compromised if the effects of reservoirs on water chemistry are not considered. This manuscript summarizes water chemistry data collected from May 2014 to Octob...
