Flow length is the main factor of soil and water conservation in hydrology. The intensity of hydraulic erosion when other conditions are the sameAccording to the length of the slope through which the flow passes, the longer the slope is, the greater the collected flow is, and the stronger the water erosivity is. Flow lengthThen it affects the speed of surface runoff, thus affecting the erosivity of surface soilData is divided into downstream and upstream
