Analisis Erosi Pada Sub DAS Lematang Hulu
Sari: At upland areas erosion
often occurwhich is caused by soil erosion due to rainfall kinetic energy and
other influences such as sensitivity of
soil erosion , land use , length and slope of river. The purpose of this study
is to calculate the erosivity index and determine the amount of erosion in the
sub watershed Lematang Hulu , which is a hilly area in South Sumatra.
In this study, the model RUSLE ( Revised Universal Soil Loss Equation )
was used to estimate the amount of erosion
caused by kinetic energy that work on the area.
The results show the maximum erosion is 5904.146 Tons/Ha/Year,the minimum
erosion is 4.168 Tons/Ha/Year, while the average erosion is 2904.157
Tons/Ha/Year. In general, the average erosion rate in the study area is 4,168 Tons/
Ha/Year.
