Deriving River Network & Catchments from a DEM using QGIS

In this tutorial, you will learn how to derive a river network through the identification of Strahler Order, and how to derive the corresponding catchment (watershed) pertaining to a defined outlet location along the river. The tool which is being used for this delineation of catchment and the derivation of the stream network is the SAGA tool of QGIS.

⭐NOTE:
‘Kite’ is an excellent tool that can help you boost your productivity when it comes to programming with its free Artificial Intelligence (AI) powered coding assistant. Kite is a plugin which provides smart completions and documentation as you’re typing-in your code, and its compatible with most of the well-known IDEs such as PyCharm, Spyder and VS Code. I absolutely love it, and recommend you guys to try it out as well.
