SMS:TUFLOW Material Properties

TUFLOW Material Properties dialog

Material properties include roughness and hydrologic losses (if used). TUFLOW uses a manning n value for roughness which can be specified as a single parameter or it can vary with depth. Hydrologic losses include an initial loss (in mm) and a continuing loss rate (in mm/hr). Hydrologic losses are generally only necessary when using direct rainfall on the model domain.

Material Sets

Multiple definitions of material properties can exist in a project. Each definition includes the material properties for each material in SMS and is referred to as a "material set." A material set can represent roughness for different conditions such as winter/summer conditions or can be used in a sensitivity analysis. To build a material set, the TUFLOW solution must already be built. Right-click on the project explorer item labeled "Material Sets" and choose New Material Set.

Editing Material Properties

Material properties can be edited by right-clicking on the material set in the project explorer and choosing Properties. This will bring up the TUFLOW Material Properties dialog.
