Research on a New Physical Based Hydrological Model Applied in Ebinur Lake Basin in China

摘要

The physical based hydrologic model based on grid-scale for water resources management (WYJ) wasapplied into the Ebinur Lake basin in Xinjiang Province, China. Several physical parameters were consideredin this model and calculated based on the physical properties by combination with GIS tools. We haveconsidered the warm-up period in order to reduce the error accoused by the uncertainty produced from thephysical model. After the calibration and validation of the model, the results showed that the model was ableto simulating the basin hydrological processes with high efficiency especially in ground surface. The N-Sefficiency coefficient was once exceeded 0.85 in simulation periods and R 2 can also reach 0.92. We candraw a conclusion that this physical model can be applied into the Ebinur Lake basin and can provided fordecision making for the government.
