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

The physical based hydrologic model based on grid-scale for water resources management (WYJ) was applied into the Ebinur Lake basin in Xinjiang Province, China. Several physical parameters were considered in this model and calculated based on the physical properties by combination with GIS tools. We have considered the warm-up period in order to reduce the error accoused by the uncertainty produced from the physical model. After the calibration and validation of the model, the results showed that the model was able to simulating the basin hydrological processes with high efficiency especially in ground surface. The N-S efficiency coefficient was once exceeded 0.85 in simulation periods and R2 can also reach 0.92. We can draw a conclusion that this physical model can be applied into the Ebinur Lake basin and can provided for decision making for the government.
