Template:D8 Flow Accumulation

D8 Flow Accumulation

This tool generates a flow accumulation grid that shows how much water flows through each part of a landscape. It uses the D8 algorithm, which directs water from each cell to only one neighboring cell that is lower down.

Input parameters

• Input raster DEM or D8 pointer file – Select the file that will be generated into a grid.

Output parameters

• Output raster file – Enter the name for the new generated grid.
• Output type; one of 'cells' (default), 'catchment area', and 'specific contributing area' – Select the type of grid you want to be generated.
