2. Building Your own Tool

We will use the example of Task 1 from Lab 7 to illustrate the value of the Model Builder. If you did not do that task, the only two inputs we need to delineate a watershed are a DEM and a pour point (provided in this file or you can use what you used in Lab 7). In this first video tutorial, we walk through how to create a model of that same sequence of steps:

In the second video tutorial, we go through how to make the model a more flexible tool that can be applied to any user input of a DEM and pourpoint:

If you want to take a tutorial on a slightly more elaborate version of this tool, see here.
