matBRAT - Beaver Restoration Assessment Tool (Matlab based - version 1 to 2.03)

View the Project on GitHub


April 2013 - Logan


Participants will learn about the beaver dam capacity model in BRAT and how to modify the model and run it for their own study areas.


What you need to do BEFORE Workhsop

Most of the day will be devoted to nuts and bolts of the GIS processing of BRAT. We’ll need and want to move reasonably quick through the different steps and I want to make sure we don’t digress into a basic ArcGIS training session (see here if you need a refresher). To facilitate this I am going to ask that all participants for the rest of the day will need to:

Prepare your Laptop

Choose your Study Watershed

Choose a tractably sized watershed or study area for workshop (e.g. Logan River Watershed as opposed to the Mississippi).

The data requirements for the beaver dam building capacity model we run are spelt out here.

I will have backup datasets to use for each exercise, should someone’s ‘own’ data fall short.
