Looking to improve your hydrology analysis skills in ArcGIS? In this tutorial, we'll walk you through step by step on how to compute the Stream Power Index (SPI). This essential GIS tool helps determine landforms and stream erosion potential. Follow along and learn how to utilize this powerful tool for your projects!
In this tutorial video, you will learn how to compute the Stream Power Index (SPI) using ArcGIS.
Stream Power Index (SPI) serves as a metric for assessing the erosive potential of flowing water, determined by factors such as slope and contributing area.
The SPI calculation is expressed as follows:
SPIi =ln(DA i⋅tan(G i ))
Negative SPI values indicate deposition, while positive values signify erosion.
If you have any specific queries or require further clarification on the SPI calculation process using ArcGIS, feel free to ask on the comment section
