Simulation of sediment transport models for small basin (apply for Suoi Sap basin in Son La province )

Abstract

     Suoi Sap Basin located in Moc Chau, Yen Chau, Bac Yen, Mai Son, Van Ho of Son La province, with area 1085 km2, accounting for 7.66% of the total area of the province. The Suoi Sap basin located in the geographic scope: 104011'09 '' - 104042'54 east longitude, 20042'8 - 21010'15 north latitude, west Nam Pan stream basin, east of Van Lake, south Laos. Surface water resources of the Suoi Sap basin are 1.4 billion m3. Total flow in 5 months of flooding season is about 80% of the total annual flow, maximum flow often focuses in August every year, the driest month occurs in March. Basin topography is complicated, fragmented and often steep slopes should be in , erosion. This article introduces a model _SDM_BASIN_2014 (The sediment transport model version 2014) simulate sediment transport in Suoi Sap Basin of Son La province.
