WebUsage. 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. WebCells with undefined flow direction can be flagged as sinks using the Sink tool. If a cell has the same change in z-value in multiple directions and is not part of a sink, the flow direction is assigned with a lookup table defining the most likely direction. See Greenlee (1987).
