Abstract
Soil erosion causes topsoil loss and downstream siltation, which has an adverse effect on the soil and
water conservation of the watershed area and also reduces the reservoir capacity. Soil erosion estimation is commonly
performed using empirical formulas and manual on-site surveys. However, empirical formulas can only be used to
estimate the annual soil erosion, and on-site surveys are limited by time and space. To address the aforementioned
problems, this study used the Geo-spatial interface for WEPP (GeoWEPP) to establish a hydrological model of the
Nanhua reservoir watershed area in Taiwan, then simulated sediment erosion and deposition, and finally, validated the
modeled output with the on-site monitoring and measurement of the new siltation amount in the reservoir. The results
indicated that the error between the simulation and measurement data was 19%–25%, which can be used as the basis for soil and water conservation measures and sediment capacity control of the watershed area
Key Words: Soil erosion, Reservoir siltation, GeoWEPP.
