Pywr-DRB: An open-source Python model for water availability and drought risk assessment in the Delaware River Basin

Pywr-DRB is an open-source, Python-based water management model of the Delaware River Basin (DRB) built on the pywr simulation framework. The model represents the basin’s major reservoirs, New York City’s out-of-basin diversions, and the operating rules of the Flexible Flow Management Program (FFMP), and it can be driven by a range of alternative streamflow datasets (observed, USGS National Hydrologic Model, NOAA National Water Model, and reconstructed flows).

My contributions to this work included developing the streamflow reconstruction inputs (prediction in ungauged basins), the regression-based inflow scaling methodology, and model diagnostics.
