In this study, Watershed Analysis Risk Management Framework (WARMF) model was applied for hydrologiy and sediment simulation and analysis of non-point loads of SS into rivers at catchment level in the Hangbu-Fengle River Watershed of Chao Lake. The study area was divided into 37 catchments by using AVSWAT2000 model, and based on analysis of the relation between topography and soil type within the study area, the 37 catchments were classified into four groups, including plain, hummock, hill and mountain. Observed hydrologic data and suspended sediment data in 2000-2003 were used for model calibration and validation. Study on calibration and validation of hydrology and sediment parameters indicated that WARMF model was applicable for hydrology and sediment simulation in Fengbu Hangle River watershed. Analysis of non-point loads of SS into rivers at catchment level showed that the catchments were divided into five classes (Class A, B, C, D and E) according to the non point SS loads at each catchment. The Class A and Class B catchments, which accounted for 82.01% of the total non-point sources loads, can be considered as the key SS control zones, the total area of which was 34.78% of the subject watershed, and the zone were distributed mainly in the middle-low mountain area of the Hangbu River branchs.
