Portable floodplain delineation from DEM and stream network.
Delineate unconfined valleys and floodplain extent using the Valley Confinement Algorithm (VCA) — combining slope thresholding, cost-distance analysis, and flood surface modelling. Built on terra for R-native raster processing. Bring your own DEM and streams; works anywhere.
See the Valley confinement vignette for a full walkthrough with bundled test data, and the function reference for individual components.
The flood model uses the VCA bankfull regression to estimate flood depth at stream cells:Read the full README ↗The full README is unavailable right now. Read it at the original link. The saved excerpt is shown below.
