Principle and practice of construction of Karez Well typed groundwater reservoir within depress zone of mountain-front alluvial plain in arid region

The problems from the construction of the surface water reservoirs under construction in arid region at present are analyzed herein， while the necessities and basic conditions of the construction of the groundwater reservoir in arid region are illustrated as well. On the basis of introducing the hydro geological condition of the water-bearing structure of the depress zone within the alluvial pain in front of medium-small sized river and the structural characteristics of Karez Well， the basic principle of the structural characteristics of Karez Well typed groundwater reservoir and the regulation and storage of water resources are expatiated. Furthermore， Karez Well Typed Groundwater Reservoir in Tailanhe River Watershed of Wensu County in Xinjiang is briefly described， and on the basis of which， the characteristics， economy and efficiency of the groundwater reservoir are explained with the relevant comparative method and quantified indexes.
