-QGIS Processing scripts for rescaling flood hazard rasters that includes the following tools:
-- Resolution enhancement (i.e., Downscaling): Three methods for interpolating a high resolution WSE grid using a high resolution DEM and simple hydraulic assumptions described in [Bryant et. al., (2022)](https://hess.copernicus.org/preprints/hess-2023-156/). For more advanced applications and features, see the [FloodDownscaler2](https://github.com/cefect/FloodDownscaler2) project.
-- Aggregation via Averaging: Two methods for coarsening flood hazard grids described in [Bryant et. al., (2022)](https://doi.org/10.1029/2023WR035100)
