Peatland drainage alters soil structure and water retention properties: Implications for ecosystem function and management

Published in Hydrological Processes, 2022

Here, we study how historic wetland drainage permanently changed soil properties in the Great Dismal Swamp.

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

Published in Environmental Modelling & Software, 2024

We introduce Pywr-DRB, an open-source water management simulation model of the Delaware River Basin that represents reservoir operations, New York City diversions, and the Flexible Flow Management Program, and use it to evaluate water availability and drought risk under multiple streamflow datasets.

Integrated river basin assessment framework combining probabilistic streamflow reconstruction, Bayesian bias correction, and drought storyline analysis

Published in Environmental Modelling & Software, 2026

First-author paper presenting an integrated framework for stress-testing modern water management policies against historical droughts. A 1,000-member probabilistic reconstruction of daily Delaware River Basin streamflows (1945–2023) is generated by combining the National Hydrologic Model, a probabilistic flow-duration-curve prediction in ungauged basins method, and Bayesian bias correction, then used to drive Pywr-DRB.
