WEPPcloud-(Un)Disturbed for United States

The WEPPcloud-Disturbed interface allows users to upload burn severity maps and predict erosion based on fire impacts. Unburned conditions can be analyzed by skipping the burn severity map. SSURGO-derived soils and NLCD landuse parameterize unburned runs, while fire and treatment scenarios procedurally generate soils and managements from the disturbed database using soil texture and landuse.

This workflow enables meaningful comparisons across unburned, burned, and treatment conditions and incorporates the Wildfire Ash Transport And Risk estimation tool (WATAR).

3180 projects and 1,186,951 hillslopes (0 WATAR hillslopes) ran since January 1, 2024.

WEPPcloud-(Un)Disturbed-WBT

WEPPcloud-(Un)Disturbed-WBT is the successor to TOPAZ-based delineation for the (Un)Disturbed workflow. It uses the WhiteboxTools hard fork WEPPcloud-WBT for watershed preprocessing and hillslope delineation.

In addition to improved performance, the WBT backend emits useful GeoTIFF (`.tif`) raster products, supports additional batch-processing utilities, and enables advanced workflows such as Omni contrasts (for example, stream-order pruning).

WEPPcloud-Revegetation for United States

The WEPPcloud-Revegetation interface supports burn severity uploads and leverages historical vegetative cover data from the Rangeland Analysis Platform (RAP) to model post-fire hydrology and erosion. Users can simulate stochastic wildfires, recovery trajectories, and cover transformations across perennial, annual, shrub, and tree components following the fire event.

58 projects and 48,941 hillslopes ran since January 1, 2024.

WEPPcloud-EU

WEPPcloud for Europe uses ESDAC landuses to assign managements and builds soils from ESDAC and EU-SoilHydroGrids data. U.S. climate stations are selected using E-OBS monthly precipitation and temperature patterns.

The PeP interfaces extend post-fire erosion modeling and WATAR ash transport modeling by parameterizing soils based on burn severity and soil texture via Disturbed WEPP soil files.

This project has received funding from the European Union's Horizon 2020 research and innovation program under grant agreement No 10100389.

47 EU projects and 14,236 hillslopes ran since January 1, 2024. EU WATAR hillslopes ran since January 1, 2023 0.

WEPPcloud-AU

WEPPcloud for Australia assigns managements from the Land Use of Australia 2010-11 dataset and constructs soils from ASRIS data. U.S. climate stations are selected using AGDC monthly precipitation and temperature patterns.

4 EU projects and 1,063 hillslopes ran since January 1, 2024. EU WATAR hillslopes ran since January 1, 2023 0.

WEPPcloud-(Un)Disturbed-Earth

The Earth interface extends the disturbed or undisturbed workflow to watersheds outside the dedicated U.S., EU, and AU configurations. It uses Copernicus DEM 30 m, C3S land cover, ISRIC soils, and climate localization from the GHCN-backed CLIGEN station catalog.

Watershed delineation uses the newer WEPPcloud-WBT backend rather than the older TOPAZ path. Use it when you need a first-pass watershed model in locations where no more specialized regional interface is available. You can skip burn severity for undisturbed conditions or add burn severity for post-fire screening, including ash transport and debris-flow workflows.

WEPPcloud-RHEM

Run the Rangeland Hydrology and Erosion Model (RHEM) across the United States. Where available, foliar and ground covers are estimated from NLCD Shrubland 2016 data, while SURGO/STATSGO identifies soil textures.

0 RHEM projects and 0 RHEM hillslopes ran since January 1, 2024.
