Template:SRH Materials Workflow

1. Create a SRH-2D Materials coverage.

1. Create new coverage from scratch. Select Map Data in the Project Explorer and use the New Coverage right-click command. Use the New Coverage dialog to create a new coverage by selecting the desired coverage type, and naming the coverage. 2. Create new coverage from an existing coverage. Use the Duplicate command on an existing coverage. This will copy any feature objects on the coverage. Use the Rename command to give the coverage a new name. Change the coverage type.

2. Digitize material areas (polygons).

3. Define material types and Manning’s roughness values.
Right-click on the materials coverage and select the Materials Properties command. In the Materials Properties dialog, add materials and assign Manning's n values.

4. Defining materials from land use GIS data.
