In fall 2023, USGCRP agencies and their partners jointly held a second workshop on Integrated Hydro-Terrestrial Modeling (IHTM 2.0) for U.S. federal and non-federal scientists and managers in Reston, Virginia, aiming to advance community modeling and integrated water resources management capabilities following open science principles. This workshop focused on developing national and regional testbeds that employ state-of-the-art modeling approaches to explore gaps and opportunities for improving the representation and extensibility of hydrologic processes and modeling across scales. Proposed integrated modeling testbeds span across the Mid-Atlantic, Upper Colorado River Basin, Great Lakes, and Gulf Coast/Mississippi regions, exploring issues such as water extremes, water quality, water use, and urbanization.
The community workshop report and a companion federal summary are under development and will be published in fall 2024.
