Calculate the Stream Power Index and Sediment Transport Index with PCRaster Tools in QGIS
This video shows how to calculate two geomorphological indices that are useful for estimating erosion potential. The first one is the Stream Power Index (SPI), which is a geomorphological metric used to quantify the erosive power of water flow in landscapes. It’s a measure of the potential for water to do work on the landscape, eroding, transporting, and depositing sediment. Next, we calculate the Sediment Transport Index (STI), which is a measure used in geomorphology to quantify the potential for erosion and deposition in a landscape.
After showing how to manually calculate the result, you'll also see how to get the tools from the QGIS Resource Sharing plugin repository and add them to the Processing Toolbox.
