39-m Resolution Stream Power Index
Description
Stream power index (SI) takes into account both a local slope geometry and site location in the landscape combining data on slope gradient and catchment area.
Stream power index can be used to describe potential flow erosion at the given point of the topographic surface. As catchment area and slope gradient increase, the amount of water contributed by upslope areas and the velocity of water flow increase, hence stream power index and erosion risk increase.
Stream power index controls potential erosive power of overland flows, thickness of soil horizons, organic matter, pH, silt and sand content, plant cover distribution.
