Stream Ordering (Strahler) from DEM Data in ArcGIS || Hydrological Analysis

Stream ordering is a method of assigning a numeric order to links in a stream network. This order is a method for identifying and classifying types of streams based on their numbers of tributaries.

Process of Stream Ordering
This step-by-step tutorial will teach you exactly how to do that. In this tutorial you will learn how to:
1. Derive a stream network using the spatial analyst tools of ArcGIS
2. Use the Raster Calculator to create a new raster with high flow accumulations
3. Derive the order of the streams
4. Export the stream network raster into a network of polylines
