Journal Title: Academic Research International - Year 2015, Vol 6, Issue 2
Abstract
Greater soil erosion is compared with the erosion of tolerance is one of the forms of land degradation are common throughout the world, both within the small region to large areas such as the scope of the Watershed and cause a decline in land productivity, water quality and disruption hydrological system until causing the failure of the environmental sustainability. The research has done with the aim of identifying, analyzing and mapping the erosion that occurs as a result of different land uses in Krueng Sieumpo watershed in Aceh Province. Determination of erosion value is done by using a predictive evaluation of erosion with RUSLE, and erosion hazard index was calculated by compared soil erosion value with the tolerable erosion. The results showed that the erosion rate of 1.9 – 1.343,4 ton/ha/year, and tolerable erosion value was13.70 – 21.26 ton/ha/year. The rate of erosion is divided into categories of mild, moderate, high and very high with the major factors affect is the amount of erosion that occurs is the slope, slope length, crop management / land use, soil management and soil erodibility.
