SCIMAP Toolkit
SCIMAP tools for catchment delineation, sediment and FIO risk mapping, network index, and flood risk mapping, with a guided panel, land cover risk weighting, and automatic result styling.
Calculates SCIMAP spatial indices including network connectivity, erosion risk, in-channel risk, seasonal FIO delivery risk, and flood mean/stdev outputs using Whitebox Workflows hydrological processing (depression breaching, FD8 and D8 flow routing, D-infinity mass flux, watersheds and downslope distances) and a flow-path trace connectivity approach. Tools: SCIMAP Sediment, SCIMAP FIO, Delineate Catchment, Apply Land Cover Risk Weights, Network Index, SCIMAP Flood, Overland Flow Distance to Point, Export SCIMAP Results, and the three SCIMAP Fitted tools, numbered to be run in order (1 Catchment Statistics, 2 Calibrate Weights, 3 Ensemble Risk Maps), which infer land cover risk weights from observed water quality rather than assuming them. A guided SCIMAP panel mirrors the SCIMAP web application workflow with click-on-map pour points and impact points, an editable risk weight table, and parameter set XML that is interchangeable with the web application. Land cover rasters are reclassified into SCIMAP risk weights in the plugin, so no pre-weighted raster is required. Outputs are styled automatically with percentile-stretched colour ramps and can be exported as GeoPackage, KML, point vectors, or Cloud-Optimised GeoTIFF. Needs Whitebox Workflows, which the plugin offers to install into the QGIS profile; it has builds for Windows (x64), macOS on Apple silicon and Linux (x86-64). https://doi.org/10.1016/j.ecolmodel.2010.08.022
