WebFlowlength is calculated as the average of the runoff pathway lengths from all the cells in a raster-based map of the target site. We evaluated the relationships between the connectivity of runoff sources, measured with Flowlength, and the runoff and sediment yields from six plots and three catchments in semiarid southeast Spain. Flowlength WebNov 16, 2024 · The function returns the flowlength in cell size units. So you have to multiply by the map resolution to get the flow in meters. Value. A matrix of the same size as DEM.
