Advanced Options
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..

Soil Options

Hillslopes with burn severity landuses will have soils altered to model burn severity.

Advanced Options
Use internal hydraulic conductivity adjustments (ksflag)

Should be off 7778. Does not affect 9001 and 9002 soils. (Experimental use for Agriculture Only.)

Flowpath Processing

Running flowpaths produces a gridded soil deposition/loss map, but runtime is considerably longer.


Hourly Seepage

Computes hourly instead of daily seepage calculations. Only applies to projects with 7778 soils (Not WEPP-PEP).


PMET

Computes evaporation and transpiration (ET) based on Penman-Monteith’s equation. The default is Penman’s equation.

For guidance on the parameters please see:
https://www.fao.org/3/x0490e/x0490e00.htm


Frost

Adjustment of effective hydraulic and thermal conductivity for snow, frozen-residue, and frozen-soil.

Run Frost (frost.txt)

Snow

Adjustments for snow.

Clip Soil Depth

Deep soils may lead to excessive water being ended up stored in soils and limited runoff.
