Sustainable soil conservation plan based on the erosion danger level by using avswat 2000

Abstract

This research conducted on the Catur sub-watershed-Kare District with the area of 190.85 km2. The study location is oriented on the Kare District-Madiun Regency which included four villages such as the Kepel, Kuwiran, Kare, and the Bodag. This research intended to study the value of erosion and sedimentation for analyzing the Erosion Danger Level (TBE). Result of the TBE analysis can be used as the base on determining the Village Soil Conservation Plan (RKTD) in the Kare District. The pparameters of the Catur sub-watershed condition during the 10 years will be processed by using the AVSWAT 2000 for producing the value of erosian and sedimentation on the Catur sub-watershed. Result shows that the Erosion Danger Level (TBE) in the Bodag village is in the level of light to heavy (21.89%), however, in the Kuwiran village is in the level of light to heavy (14.46%), in the Kepel village is in the level of light to moderate (22.23%), and in the Kare village is in the level of light to moderate (41.31%). The Village Land Conservation Plan that is applied in the Kare sub-district are conservation by the vegetative and mechanical method, however, in the Bodag village and Kuwiran by the vegetative conservation method with the regulation of land use, in the Kare village by the vegetative and mechanical conservation method with the regulation of land use and by building the two check dams, and in the Kepel village by the mechanical conservation method with building a check dam. The result is hoped as the reference for the recovery and management of the sustainable soil conservation.
