Hydrology Data Access, Scripted
The fastest productivity win in computational hydrology is scripting your data access: dataRetrieval and hydrofunctions for USGS records, HyRiver for the whole US data landscape, rnrfa for UK flows, fasstr for Canadian records, cdsapi for ERA5 reanalysis, and the ARR Data Hub and NOAA Atlas 14 for design rainfall. Reproducible inputs make reproducible studies — this collection is where that starts.
