Simulation of Snowmelt and Runoff Based on Component in Northwest of China

Liu Yang, Yang Yongchun, and Zhang Ke
Abstract—Integration has become an efficient method in nature resources assessment and management along with the need of achieving the goal of sustainable natural resource management. The physically based cold regions hydrological modeling platform (CRHM) was used to create two cold region hydrological models for Binggou watershed, located in northwestern of China and Zuomaokong watershed, located in the hinterland of the Qinghai-Tibet plateau. To evaluate CRHM, simulations of snow depth with/without sublimation module compared to observations were carried out in Binggou watershed. Another comparison which aimed at finding out what influence the frozen soil has to runoff was implemented in Zuomaokong watershed. The model performance in predicting snow depth and runoff was evaluated against field observations. Root-mean-square error (RMSE) between simulation and observations ranged from 0.067949 to 0.076158 for the simulated snow depth in 2007/2008, with higher RMSE in the simulation that the sublimation module was used. The model was able to capture the timing and magnitude of peak autumn basin discharge, but it underestimated the basin discharge without the frozen soil module included in spring 2008 and 2009, respectively. The results suggest prediction of northwestern of China snow hydrology is possible with no calibration if physically based models are used with physically meaningful model parameters that are derived from high resolution geospatial data.
