Calculate the potential erosion at Wae Heru and Wae Tonahitu Watershed aims to map and assess the potential erosion, in order to be a scientific consideration for exploration and development. The method is a field survey to determine the forms of land use and other forms of conservation efforts; secondary data collection, i.e. soil data, rainfall data, slopes data and data interpretation from Geo Eye satellite imagery in 2012. Further data processing used USLE formula with ArcGIS program. The results showed that the potential erosion of Wae Heru Watershed and Wae Tonahitu Watershed are in very light potential class. This is because the conditions in the upstream are still forested largely. However, at the downstream potential for erosion is vary, i.e. light class, moderate class, heavy class and very heavy class. This is because the conditions in the downstream undergo conversion into settlement, moor, garden, open land and sand mining.
