The hydro-climatic trends were examined for the lower reach of the Shiyang River Basin in NW China using the wavelet analysis and the Mann–Kendall (M–K) test. In order to identify the optimal combination of the hydro-climatic data series in the discrete wavelet transform (DWT), the results from DWT were tested by the Mann–Kendall test. The results showed that the discharge significantly decreased...
The quantitative assessment of geothermal water resources is important to the exploitation and utilization of geothermal resources. In the geothermal water systems the density of groundwater changes with the temperature, therefore the variations in hydraulic heads and temperatures are very complicated. A three-dimensional density-dependent model coupling the groundwater flow and heat transport is...
