In Indonesia, agricultural fields have the problem of soil loss. The USLE model can estimate annual soil loss and it’s composed five factors. There are two purposes in this study. First is to evaluate accuracy of ASTER GDEM comparing ground observation data for calculate topographic coefficient (LS) which requires watershed area data and slope angle data. Second is to compute the potential risk of soil loss in Cianjur using LS, land use coefficient (C) and soil coefficient (K). C and K factors are given from empirical constants. And the high risk areas are found in the parts of northwest and southeast. |
