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

• shapely

• pygeoprocessing
