2. Summary

This paper is written to model the variation of water budget between 1990 and 2000 in the Yeongsan river basin, using SWAT. Almost the same data including meteorological and water quality data is used except the usage of the river basin. Sensitivity analysis, calibration, and validation are carried.

 

There are some changes from 1990 to 2000. In 1990, the baseflow alpha factor is the first factor and the initial curve is second, but in 2000, the order is changed. And, compared to 1990, the ratio of urban is increased, but forest and agriculture areas are decreased. Also, surface runoff is increased, although lateral flow and transpiration are decreased. Therefore, it is verified that urbanization affects the water budget in the watershed basin.
