Uniform values are assigned from the Index Maps command in the GSSHA menu. Using this dialog, a new index map can be created, and then the Constant to Array button used to assign a single ID number to every cell in the active grid. This uniform index map may then be assigned to any given process. The uniform index map could be assigned for overland roughness in the following manner. Select the Edit Mapping table button. Select Roughness from the process list and the uniform index map from Assigned index map. ID numbers may be automatically generated from the index map by selecting the Generate IDs from map button. Alternatively, hitting the Add ID button will also generate IDs, but in a numerically sequential order. Parameter values for each ID are entered by selecting the ID number under ID and then filling in the information in the Selected ID property table, which will be Surface roughness in this example. Select Done when finished.
