An area property coverage is used to map properties such as Manning's roughness values to the mesh, grid, or cross-sections.

Materials are used to define different values for the property the material represents. For example, if the material represents the Manning's roughness value, materials are defined to represent the different Manning's roughness values to be included in the model (stream, floodplain, field, roadway, etc.). Polygons can then be created to define the stream, floodplain, field, and roadway with the corresponding material assigned.

Materials are assigned a name, color and pattern for display, and model specific attributes.

Many of the data entities constructed and edited in SMS (i.e., elements, cells) have a material ID associated with them. This material ID is an index into a list of material types. Materials contain model specific parameters such as manning's roughness, or bed material grain size. A global list of material attributes is maintained and can be edited using the menu command Edit | Materials Data. This command brings up the Materials Data dialog where each material is assigned an ID number. This dialog can be used to delete unused materials, create new materials, and assign a descriptive name, color, and pattern to a material. This general information is saved in the material file. The materials defined within the Materials Data dialog are available for all modules.

Area Property Polygon Attributes Dialog

Land Polygon Attributes dialog

The Land Polygon Attributes dialog is used to set the attributes for feature polygons. It is reached by double-clicking on a polygon in an Area Properties coverage. Attributes that can be specified for each polygon include:

  • Polygon Type
  • None – No attributes are assigned to the polygon.
  • Material – With this option selected, a material can be assigned to the polygon from the drop-down list below. Only materials defined in the Materials Data dialog before they can be assigned to a polygon.
