Hydrological & Terrain Analysis Tutorial Using WhiteboxTools

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
