Identification of Erosivity Potential on Tropical Zone Using Spatial Method

As a geological process that wears away soil, rock, or dissolved material, erosion may result in the loss of soil layers are rich nutrients for plant growth and reducing ability to absorb store water. High rainfall causes high level erosivity which can lead increase intensity. Therefore, predicting erosion, rain condition needs be considered most, especially tropics. This study was conducted Samboja District, East Kalimantan Province, Indonesia. The purpose this is create zoning potential based on topographic correlation with land cover support practices factors spatially map form. uniform distribution types allows integration erodibility factor together factor. Several equations suitable tropical areas were used estimate using BMKG data last 16 years (2006-2020). results maps at minimum, maximum, average conditions. change from minimum occurred only very limited points, it almost negligible. A significant found under maximum potential. striking zone Class III IV, IV V.
