The USGS National Hydrologic Model (NHM) infrastructure supports the efficient construction of local-, regional-, and national-scale hydrologic models. The NHM infrastructure consists of: 1) an underlying geospatial fabric of modeling units with an associated parameter database, 2) a model input data archive, and 3) a repository of the physical model simulation code bases.
CONUS404 is a unique, high-resolution hydro-climate dataset appropriate for forcing hydrological models and conducting meteorological analysis over the contiguous United States. It was produced by the Weather Research and Forecasting (WRF) Model simulations run by National Center for Atmospheric Research (NCAR) as part of a collaboration with the U.S. Geological Survey (USGS) Water Mission Area.
Substantial advances in water science, together with emerging breakthroughs in technical and computational capabilities, have led the USGS to develop a Next Generation Water Observing System (NGWOS). The USGS NGWOS provides real-time data on water quantity and quality in more affordable and rapid ways than previously possible, and in more locations.
Building on the development of IHTM as a framework to address the complex water challenges in the United States, the IHTM 2.0 Workshop Report presents the findings from the IHTM 2.0 Workshop. This event brought together 160 scientists and managers from federal, academic, and private sectors to strengthen critical connections between the research and operational water resources communities in fall 2023.
Weekly updated drought/wetness maps based on the assimilation of Gravity Recovery and Climate Experiment (GRACE) and GRACE Follow On (GRACE-FO) data into a land surface model.
The CSDMS 2025 Annual Meeting will be broad in scope, bringing together CSDMS members to present new scientific insights in the modeling of surface dynamics and the impact of time and process scales, new advances in cyber-infrastructure, examples on coupling models, how social and ecological models can inform management, and more. Also, this is the 3nd year that you can submit Electronic Publications (Epubs); Jupyter notebooks that contain e.g.
EPA’s water research supports solutions that ensure adequate supplies of clean water resources to protect our health and livelihood, protect and restore watersheds and ecosystems, and strengthen our economy.
Surface water quality models are critically important tools for managing our nation's surface waters. EPA's Water Modeling Workgroup (WMW) works to facilitate the use of surface water quality models through collaboration, information sharing, and training on models and modeling resources.
