Changing Manning's roughness by a percentage for an area of interest

[praalankar 0]

Hi there,

I'm looking to do a sensitivity analysis for the Manning's roughness for a particular area in a basin.

I see that we can use Read Materials File == My_Materials.tmf | 1.1 command to define the % change, but that would make a global change. Is there a quick way of changing the material roughness for a given region defined by a shapefile? I just want to avoid creating multiple 2d_mat shapefiles.

 

Thanks,

Prabhanjan

Hi Prabhanjan,

There is no such way that could do this without creating multiple shapefiles. However I have noted this to the TUFLOW development list for a consideration.

 

Kind regards,
