"WebNov 12, 2024 · There seem to be two different primary trains of thought on flow length. One is to use the longest flow path of your subcatchment, and the other is to define the flow length as the overland flow length, which typically doesn't exceed 10-300 feet. There is another critical tuning parameter that works in concert with subcatchment width, and that ... " - Flowlength计算

WebFlow Length. Flow Length is the horizontal projection length of the greatest surface distance from a point on the surface to the beginning (or end) of the stream along the flow direction. Flow length is a crucial factor for soil conservation; if the flow length is long, the flow volume will be huge and the erosion will be stronger.
