Hydrological Simulation of Taizi River Basin with HSPF Model

Abstract

With the development of economy and the increase of population, water resources are becoming more and more scarce. The total amount of water resources in the Taizi River Basin of Liaoning Province, China is 5.120 billion m3, and the per capita water resources amount is 845 m3. According to the United Nations standards, it is classified as a water shortage area.In order to better manage and protect water resources, this paper uses Hydrological Simulation Program-Fortran (HSPF) model to simulate runoff in the Taizi River Basin. The Parameter Estimation (PEST) procedure was used to calibrate the hydrological parameters. The results showed that the Nash-Sutcliffe efficiency (NSE) of the calibration period (2009-2011) was 0.78, the correlation coefficient (R2) was 0.89; the Nash-Sutcliffe efficiency of the validation period (2012-2013) was 0.68, and the correlation coefficient was 0.85. It indicates that the HSPF hydrological model has good applicability in the Taizi River basin which will provide useful reference for future modeling research.
