Now that we have a project setup and a projection defined, we can import the terrain. It is recommended that you clip the terrain raster to a buffer of the basin boundary. I used a buffer of 1km because if any part of 2D mesh extends beyond the terrain, the model will not run. IContinue reading “Create a Terrain”

Setup the RAS Project
Starting a new RAS project is always exciting, possibly because my mistake counter is at 0. I am using HEC-RAS 6.4.1 since that is the latest version as of right now. Project Naming An end user should be able to get a general idea of the project from the file name. Any file (and folder)Continue reading “Setup the RAS Project”
Delineate the Basin Boundary
We need to delineate the basin boundary if we want to build a 2D model of a watershed. A watershed is an area of land that drains all the streams and rainfall to a common outlet such as the outflow of a reservoir, mouth of a bay, or any point along a stream channel. TheContinue reading “Delineate the Basin Boundary”
Let’s Create a 2D RAS Model
Let’s create a 2D RAS model of the Caroni River basin in Trinidad. Any data presented here is only for educational purposes and is not to be used for commercial or political purposes. This will be in form of a rough tutorial. If you want more details, find a way to contact me. Each postContinue reading “Let’s Create a 2D RAS Model”
