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:

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
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

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