SAGA.ta_hydrology.26: Slope Limited Flow Accumulation

Flow accumulation is calculated as upslope contributing (catchment) area using the multiple flow direction approach of Freeman (1991). For this tool the approach has been modified to limit the flow portion routed through a cell depending on the local slope. If a cell is not inclined, no flow is routed through it at all. With increasing slopes the portion of flow routed through a cell becomes higher. Cells with slopes greater than a specified slope threshold route their entire accumulated flow downhill.

Assume a given minimum slope for each cell.

number

Slope threshold, given as degree, above which flow transport is unlimited.

number

Use Flow Threshold

boolean

Flow threshold, given as amount of cells, above which flow transport is unlimited. Ignored if range equals zero.
