Abstract

Abstract

The present water-resources assessment for northwestern China is based on such hydrogeological concept model: (1) A barrier resisting water exists between mountains as a main source of runoff and basin; (2) Almost all groundwaters generated in mountain area are converged into the river outflowing from the mountain to the oasis of the basin. The data of groundwater chemistry and isotope and geologic survey show that this model does not conform with the actual hydrogeologic situation. Based on the result of numerical simulation for generating runoff in high mountain area obtained in foreign countries, an analogue method is suggested to estimate roughly the quantity recharged laterally from mountain to oasis of basin through the basement. The construction of this new concept model may reveal the fact that a considerable quantity of water resources are buried in shallow basement rocks in the oasis of mountain-basin systems in northwestern China, which have never been counted in the reserves before.
