- Abstract:
- This research simulated runoff and sediment of Zhaosutai river basin based on SWAT model, 3S technology and basic database. The data of daily runoff and sediment transport rate from 2004 to 2009 were used to calibrate and validate the results of the model output. It proved that SWAT model was feasible for the research. Simulation results showed that average annual runoff was 1.64 m3/s and sediment discharge was 6.90×104 t. Soil erosion modulus was 62.93 t/(km2·a), which was categorized as slightly erosion . Cultivated land was the main source of sediment generation in the research area. From the results of SWAT model, runoff and sediment discharge were ranged with season. According to the characteristics of the study area, the soil and water conservation measures were proposed, and hydrological response of scenarios of different control measures of vegetation buffer zone with different scales were simulated. This research reveals the characteristics of runoff and sediment in Zhaosutai river basin, and provides data and management decision support for soil and water conservation for the study area.
