| Abstract: Huai River basin is a unique area in China with highest density of both water
projects (dams and floodgates) and population. The construction of dams & floodgates
substantially changed the basin’s natural hydrological cycle. In this study, the dams &
floodgates discharge simulation module of the Soil and Water Assessment Tool
(SWAT) was extended to incorporate the dams & floodgates’ dispatch rules. This
upgraded version of SWAT model was applied to simulate the monthly flow at
twenty-three dams & floodgates and four hydrologic stations for 1991 - 2000. Observed
flow data from a total of 27 monitoring cross-sections were used to calibrate and
validate the distributed hydrologic parameters. The evaluation coefficients (i.e. relative
volume error, correlation coefficient, and efficiency coefficient) are used to elevate the
modeling performance in the SWAT of Haihe River Basin. In the calibration period, the
volume error coefficients at 18 monitoring stations are within |
