Make a model of your watershed


Looking at a topographic map of an area is a great way to understand the contours of the land, if you know how to read a topographic map. One way to gain a better understanding of topographic maps and the land contours they represent is to turn a topographic map into a three dimensional model.

There are at least two ways to make a model of a watershed.

Ther first way is really simple, and does a great job of illustrating the basics of how a watershed works. Instructions can be found at: http://www.epa.gov/gmpo/education/pdfs/WorldBackyardActivities1.pdf

 

Another way is to turn a topographic map into a model. Basically you can cut the map along the topo lines and sandwitch the layers with cardboard of foam board to add elevation to the map. For instructions, click here. (check back for instructions soon, they are in development).
