I would like to make an hydrological conditioning of a DEM using an available stream network in vector form. I know r.hydrodem but it doesn't allow to use the stream vector. I need something to burn the stream network in the DEM to assure water flowing.
Is there a solution in GRASS?
Please check r.carve which generates stream channels by taking a vector stream map, transforms it to raster model and subtracts depth from a DEM writing out a new, modified DEM.
