WEPP

Advanced Options

For more information on the advanced processing options see the documentation

Flowpath Processing

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

Run Flowpaths

Hourly Seepage

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

Run hourly seepage (wepp_ui.txt)

PMET

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

Run PMET (pmetpara.txt)

Frost

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

Run Frost (frost.txt)

Snow

Adjustments for snow.

Run Snow (snow.txt)

Rain Snow Threshold Temperature (C):

Density of new snow (g/cm³):

Snow Settling Density (g/cm³):

Baseflow Processing

Initial groundwater storage (mm):

Baseflow coefficient (per day):

Deep seepage coefficient (per day):

Watershed groundwater baseflow threshold area (ha):

Channel Parameters

Use variable channel critical shear as a function of channel slope (tcr.txt)

Constant CS parameters

Critical Shear (N/m²) based on Median Channel Bed Particle Size (mm):

Channel Erodibility (s/m; 1e-6 default):

Bedrock

ksat for restrictive layer:

Phosphorus Processing

Phosphorus coefficients determined by lt mod

Surface runoff concentration (mg/l):

Subsurface lateral flow concentration (mg/l):

Baseflow concentration (mg/l):

Sediment concentration (mg/kg):
