delineate it watersheds
I am trying to use DelineateIT to create watersheds for many pour-points that represent groups of buildings at flood risk. When I do so, the model appears to work well for many pour-points, but for others the polygon delineated is the opposite of what I would expect: it is the entire extent of the layer that is NOT a part of the watershed (I have attached a screen shot of an example, the watershed polygon is green and partially transparent)
Has anyone else had this happen, or have any ideas about what might be causing this to occur?
