![]() Flow direction output is a floating point raster represented as a single angle in degrees going counter-clockwise from 0 (due east) to 360 (again due east). The D-Infinity (DINF) flow method, described by Tarboton (1997), determines flow direction as the steepest downward slope on eight triangular facets formed in a 3x3 cell window centered on the cell of interest. However, an MFD flow direction output raster is an input recognized by the Flow Accumulation tool that would utilize the MFD flow directions to proportion and accumulate flow from each cell to all downslope neighbors. As MFD flow directions have potentially multiple values tied to each cell (each value corresponds to proportion of flow to each downslope neighbor), it is not easily visualized. The MFD flow direction output when added to a map only displays the D8 flow directions. The MFD flow direction type only supports creation of output flow direction raster in Cloud Raster Format (CRF), such as, flowdir1.crf, within a folder workspace. A flow-partition exponent is created from an adaptive approach based on local terrain conditions and is used to determine fraction of flow draining to all downslope neighbors. (2007), partitions flow from a cell to all downslope neighbors. The Multiple Flow Direction (MFD) algorithm, described by Qin et al. The result is a map of percent rise in the path of steepest descent from each cell. Across a flat area, the distance becomes the distance to the nearest cell of lower elevation. For adjacent cells, this is analogous to the percent slope between cells. The output D8 drop raster is calculated as the difference in z-value divided by the path length between the cell centers, expressed in percentages. 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. Cells with undefined flow direction can be flagged as sinks using the Sink tool. For example, if the change in z-value is the same both to the right (flow direction = 1) and down (flow direction = 4), the flow direction for that cell is 1 + 4 = 5. In such cases, the value for that cell in the output flow direction raster will be the sum of those directions. If a cell has the same change in z-value in multiple directions and that cell is part of a sink, the flow direction is referred to as undefined. This is used to filter out one-cell sinks, which are considered noise. If multiple neighbors have the lowest value, the cell is still given this value, but flow is defined with one of the two methods explained below. If a cell is lower than its eight neighbors, that cell is given the value of its lowest neighbor, and flow is defined toward this cell. The values for each direction from the center are the following:įor example, if the direction of steepest drop was to the left of the current processing cell, its flow direction would be coded as 16. The output of the Flow Direction tool run with the D8 flow direction type is an integer raster whose values range from 1 to 255. The D8 flow method models flow direction from each cell to its steepest downslope neighbor. Those are D8, Multi Flow Direction (MFD) and D-Infinity (DINF).
