Watersheds: Iowa Landform Regions

Iowa Department of Natural Resources categorized state's diverse landscapes into 7 landform regions based on the geological formations (http://www.igsb.uiowa.edu/Browse/landform.htm). The Iowa landform project simplified these landform regions into different but similar set of 7 eco-regions for watershed modeling purpose. Two watersheds were selected in each eco-region to parameterize the SWAT model to facilitate the development and implementation of Total Maximum Daily Load program in the state.
