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. WebFlowLength example 2 (stand-alone script) This example Calculates the downstream distance along the flow path for each cell. # Name: _Ex_02.py # Description: # Requirements: Spatial Analyst Extension # Import system modules import arcpy from arcpy import env from arcpy.sa import * # Set environment settings env. workspace = …
