Predicting sediment load and runoff in Geo WEPP environment from Langat sub basin, Malaysia

Research output: Contribution to journalArticle

Abstract

This study monitors and predicts the sediment load and runoff at the UKM catchment - the Langat sub basin of Peninsular Malaysia using the WEPP software interfaced in ArcGIS 10.2. Within Geo WEPP and WEPP interfaces, TOPAZ algorithm and climate generator (CLIGEN) were used to parameterize the aspects of land cover, slope, climate, soil and topographic data and estimate stochastic climatic parameters respectively. Range of soil parameters was defined by utilizing soil properties such as frequency of soil particles, CEC and OC. The management factor was generated applying EPIC algorithm for land use types during the simulation period 2000 to 2014. The study shows that variation occurs between sediment prediction by GeoWEPP and the measured value of the same. The findings provide further the useful information about the measuring technique and status of the sediment load and runoff for the soil erosion management. This study suggests the longer span of monitoring as part of the comprehensive management plan is needed for the Langat River Basin.
