Scenario of Vegetation Density for an Erosion Prediction Model

The aim of this study is to create a scenario for investigating the factors that affect the vegetation density and to design the formulation of vegetation density as one of the factors on the revised universal soil loss equation. The methodology consists of 1) measuring vegetation density in 10 watersheds/sub-watersheds by using satellite imagery and field observation; 2) studying the factors that influence vegetation density based on literature review; 3) determining the dominant factors that influence vegetation density based on statistical analysis; 4) formulating vegetation density based on the statistical analysis results; and 5) validating the formulation of vegetation density using the universal soil loss equation as the control. The result is expected to allow for prediction of the effect of reforestation on decreasing soil erosion.
