Flowlength计算
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 ...
