SMS Project Explorer showing CMS-Flow project.

The bottom friction parameter (related to Manning mathn/math) is spatially varying (cell-specific) over the grid domain. The default value upon grid creation is 0.025. At times a user may desire to represent locations where added friction is needed due to structures or increased turbulence due to sharp changes in current speed. More information on using this feature of CMS-Flow can be found here.
