Rebuild the soils after changing managements.
Hillslope Visualizations
Gridded Visualizations (for flowpath runs)
Ash Transport Visualizations
Upload a raster SBS map (.img or .tif). The map can be a thematic SBS map or a 256 dNBR map. Preferably in UTM. Maps with color tables will use colors to assign severities.
Hillslopes with burn severity landuses will have soils altered to model burn severity.
Should be off 7778. Does not affect 9001 and 9002 soils. (Experimental use for Agriculture Only.)
Specify single storms as separate rows: mo da yr prcp(in) duration(hours) time-to-peak(%) intensity(in/hour)

Computes hourly instead of daily seepage calculations. Only applies to projects with 7778 soils (Not WEPP-PEP).
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
Adjustment of effective hydraulic and thermal conductivity for snow, frozen-residue, and frozen-soil.
Adjustments for snow.
WEPP can overpredict erosion with long hillslopes. Clipping will restrict the length and maintain area by increasing the width of the hillslope.
Deep soils may lead to excessive water being ended up stored in soils and limited runoff.
Specify Export Products on Run Completion
The ash transport analysis is available for continuous climates (no single storm). A climate with at least 100 years is recommended. The ash transport relies on WEPP outputs. Run WEPP before running this analysis.
Upload a raster load map (.img or .tif). The map should contain ash loads in tonne / ha.
Upload a raster load map (.img or .tif). The map should have assign no ash to 0, black ash as 1, and white ash as 2.
