Data

The bed density can be specified as:

·         Constant (in domain)

·         Varying in domain

The bed density is defined as the dry density.

For the case with varying in domain you have to prepare a data file containing the bed density before you set up the hydrodynamic simulation. The file must be a 2D unstructured data file (dfsu) or a 2D grid data file (dfs2). The area in the data file must cover the model area. If a dfsu-file is used, piecewice con­stant interpolation is used to map the data. If a dfs2-file is used, bilinear inter­polation is used to map the data.
