Detailed Description

Burns a stream network into a Digital Elevation Model (DEM). Stream cells have to be coded with valid data values, all other cells should be set to no data value. First two methods decrease . The third method ensures a steady downstream gradient. An elevation decrease is only applied, if a downstream cell is equally high or higher. You should provide a grid with flow directions for determination of downstream cells. The 'Sink Drainage Route Detection' tool offers such flow directions.
