"Integrated Hydro-Terrestrial Modeling: Development of a National Capability," report of an interagency workshop held September 4-6, 2019 with support from the National Science Foundation, the U.S. Department of Energy, and the U.S. Geological Survey
An interagency workshop on “Integrated Hydro-Terrestrial Modeling: Development of a National Capacity” was held at the National Science Foundation (NSF) September 2019, led jointly by the NSF, the U.S. Department of Energy (DOE) and the U.S. Geological Survey (USGS) and with broader interagency support provided through an interagency steering committee. This workshop provided a venue to bring together representatives of water-related agencies and their scientific partners (including university researchers) to initiate and refine a vision for a national Integrated Hydro-Terrestrial Modeling (IHTM) and data infrastructure and advance ideas towards its development.The workshop focused on three “Priority Water Challenge” domain areas represent targets for initiating developmentof the IHTM: (1) Nutrient loading, hypoxia, and harmful algal blooms; (2) Water availability in the western United States; and (3) Extreme weather-related water hazards.Workshop participants envisioned a future in which agencies are better aligned and creatively work through effective business and funding practices, thereby enabling IHTM collaborations and partnerships that simultaneously advance the individual missions of water-related agencies and meet the needs of their stakeholders and the nation.
