Terrain Analysis and Watershed Delineation
Hydrologic terrain analysis and understanding steps required for generating drainage networks and delineating watersheds.
About This Course
Terrain Analysis:
Elevation and related terrain variables are important components that can be used and analyzed within GIS. For example, elevation across a landscape can change. Through GIS, it is possible to determine where the water flows, what new rivers and lakes are formed, how much water accumulates on the landscape, and where floods occur, etc.
Terrain analyses are often used to develop and apply hydrologic functions and models. In this module, you will analyze topographical information using a Digital Elevation Model (DEM) to :
1. Generate a stream network (predict a potential flow path network) and
2. Generate watershed boundaries
