"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. " - Flowlength计算
