The Flow Direction tool supports three flow modeling algorithm: D8, Multiple Flow Direction (MFD), and D-Infinity (DINF). The D8 flow method models flow direction from each cell to its steepest downslope neighbor. The output of the Flow Direction tool using the D8 flow direction type is an integer raster whose values range from 1 to 255.
