Introduction
This tutorial demonstrates how to perform hydrological and terrain analysis within QGIS. The workflow begins with downloading a DEM dataset, installing WhiteboxTools, and configuring QGIS to recognize the WhiteboxTools functions. Subsequent steps includes DEM preprocessing, flow direction and flow accumulation modelling, deriving slope and the creation of a Topographic Wetness Index (TWI) map.
Data & Software Requirements
- 30 m DEM of the Kananaskis region
- QGIS
- WhiteboxTools Open Core
Step 0: Installing WhiteboxTools
Download WhiteboxTools Open Core:
After downloading, extract the .zip file and place the folder somewhere easy to find. For example, You may store it in: C:\Program Files\WhiteboxTools\
