Documentation
rios_preprocessor is meant as a replacement for the ArcGIS python code that currently produces the inputs for the main RIOS program.
rios_preprocessor produces rasters of:
Downslope retention index
Upslope source
Riparian index
Slope index
that are used as input for the following RIOS objectives:
Erosion Control
Nitrogen Retention
Phosphorus
Flood Mitigation
Groundwater Recharge/Baseflow
Along the way, there are some additional tricks rios_preprocessor uses that may be useful in other contexts:
rasterizes an input shapefile river network and matches it to a (raster) DEM/DTM
identifies discontinuous river banks along a rasterized river
identifies the end points of rasterized rivers
Dependencies
numpy
pandas
geopandas
fiona
rasterio > 1.0
