Is there anyway to alter elevation of DEM where there are bridges and dams for the flood routing of the River?
I have to calculate discharge of the River from ancient times so at that time there were no dams and bridges.
I am also struggling with that. At present time, the best solution I have found is the following:
However, I encounter many trobules when dealing with point nr.2. Close to the banks the interpolation is very poor, even though I am using an irregular kernel filter for the focal statystics analysis.
UPDATED ANSWER
I found a solution which works pretty well:
mask_0*DTM_interp
;"DTM_clipped_at_1" * ("mask_created_at_6"=0)+"DTM_interpolated_at_5"
By following these points you will interpolate a part of the raster and insert it in the old raster.
