Spatial mannings

[dvalters]

Summary

Implements an option to set the Manning's n value based on reading in a DEM with corresponding n values for each cell.

Inputs:

• A dem in ASCII format of the spatially distributed Manning's n values. It must be the same shape and size as your elevation/topo DEM
• Parameter file must have the following options set: (See Caersws.params for latest example)

spatial_mannings_dem_file:         caersws_mannings.asc
...
spatially_variable_mannings_on:     yes

This will override any value set in the mannings_n value and ignore the default value of 0.4

Can be applied in reach or catchment mode.
