Prediction of the Magnitude of Erosion that Occurs in Some Units of the Wae Tomu Watershed Sirimau District, Ambon City

Charles Silahooy


This research aims is to predict the magnitude of erosion that occurs in some units of the Wae Tomu watershed Sirimau District, Ambon City. Estimation of erosion that occurs is calculated by calculating the number of of rain erosivity, soil erodibility factor, long factor and slope, plant factor and erosion control factor. The results show that the calculation of erosion hazard that occurs in Wae Tomu watershed results vary from very light to very heavy. Therefore the possibility of erosion in the Wae Tomu watershed is very high considering the results that show the qualifications up to very heavy. With this result is expected to be a reference material for the prevention of natural hazards that may occur in the Wae Tomu watershed, which can harm the surrounding environment and humans living around the Wae Tomu watershed.
