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.)

Advanced Options
For more information on the advanced processing options see the documentation
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.


Baseflow Processing
Baseflow is not implemented for single storm climates. #312

Watershed
Clip Hillslopes

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


Channel Parameters

Constant CS parameters
Manning Roughness Coefficient

WEPP is more sensitive to chnn. chnn must be greater than chnnbr for WEPP.

Refer to this table for setting total Manning roughness (chnn) https://www.fsl.orst.edu/geowater/FX3/help/8_Hydraulic_Reference/Mannings_n_Tables.htm


Bedrock

Soils
Clip Soils

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