Clip Hillslopes

WEPP can overpredict erosion with long hillslopes. Clipping will restrict the length and maintain area by increasing the width of the hillslope.

Walk Flowpaths

This option walks the flowpaths so that wepp can run individual flowpaths. This is needed from gridded WEPP product but isn't needed for hillslope and watershed level outputs..
