Stream power index arcgis
http://iflorinsky.impb.ru/si.htm WebOutput spi raster map contains stream power index SPI, computed as α * tan(β) where α is the cumulative upslope area draining through a point per unit contour length and tan(β) is the local slope angle. The SPI reflects the power of water flow at any point in the catchment and the tendency for gravitational forces to move that water downslope (Moore et al. 1991).
