Spatiotemporal Characterization of Floodplain Inundation and Habitat

Hydrospatial Analysis R Package

An R-package for spatial and temporal analysis of floodplain inundation characteristics and application of habitat suitability criteria. It takes as input raster data of depth and velocity (e.g., from 2D hydrodynamic modeling) at known flows and a corresponding daily flow time series. Daily rasters of estimated depth and velocity are generated from inputs using spatially resolved piece-wise linear interpolation. Hydrospatial analysis functions calculate a range of physical metrics using the raster time series. Habitat suitability criteria applied to the computed physical metrics estimate spatially resolved daily cell suitability, allowing for computation of daily weighted usable area. Statistical and graphical summary of these metrics in space and time.
