Hi,
I want to ask you: What conditions (high mannig´s value from 0.10 to 0.18, ineffective areas or block obstructions) do you enter for the built-up area/developed areas, when do you solve a downstream routing of dam break wave using 1D?
How do you solve a the developed areas in the 2D model, when you have only digital terrain model (no digital surface model)? (applied to downstream routing of dam break wave)
In nowdays I use high mannig´s values for the built-up-area.
(see you annexes)
