- Abstract
Malaysia like many Southeast Asian countries is experiencing a large-scale soil erosion problem. The catchment area along with the Universiti Kebangsaan Malaysia (UKM) located in the Langat River basin in Peninsular Malaysia releases a substantial amount of sediment. Hill slopes are of sedimentary rock, susceptible to erosion from surface runoff. Establishing permanent vegetation cover is known to be an effective measure to control severe erosion. The objective of this study is to estimate the performance of hydro-mulching as a rapid control measure for soil erosion. Rainfall was measured using the digitized HBO data logger. We measured TSS concentration and discharge rates of the barren and three natural vegetation covered plots from the water samples collected during rainfall events. TSS concentration and discharge rates were measured in hydro-mulched plots. All plots were demarcated by natural fragmentation and hand prepared thin drains on top, right, and left of the slopes, wherever was necessary. The plots were digitized using ArcGIS 9.3 which measured their area slope and elevation. Validation was done through extensive field visits and reviewing existing studies. Our study shows that the performance of experimental vegetation- Resam, Vetiver, and Elephant creeper has effectiveness in controlling erosion. It may suggest that hydro-mulching is an effective measure of controlling the rapid soil erosion on the steep slope.
