Talk Description:

The NOAA National Water Model became fully operational in August of 2016 providing real-time, high resolution forecasts of key hydrologic variables such as soil moisture, shallow groundwater, evapotranspiration, snowpack and surface runoff. It also provides streamflow forecasts for over 2.7 million river reaches within and tributary to the coterminous U.S.  Since becoming operational there have been 2 significant upgrades to the modeling system that have targeted known shortcomings in the representation of certain hydrologic variables. This seminar will provide an updated overview of the National Water Model, which is based on the community WRF-Hydro modeling system, and provide examples of several different operational and experimental forecast products that are currently being generated and evaluated. Particular emphasis in this talk will focus on multi-variate verification of National Water Model simulations and forecasts that have been conducted to date. Links to ongoing collaborative research with many academic and agency partners will also be discussed.

CUAHSI's 2017 Fall Cyberseminar Series: Towards a Global Integrated Hydrology Platform: Perspectives and Advances in Large-scale Modeling

Host: Reed Maxwell, Rowlinson Professor of Hydrology (Colorado School of Mines)

Questions critical to human water use and environmental change increasingly require approaches that incorporate interconnected hydrologic processes and bridge a wide range of spatial scales. These needs have pushed models forward in both process complexity and spatial extent. Hydrology models that include connections between groundwater, surface water, land surface processes, human water use and even the atmosphere are now running at high resolution over continents and across the globe. This seminar series highlights recent research from four groups working to advance large-scale hydrologic modeling. Starting with a global perspective, these seminars will discuss various success stories and challenges as the hydrology community advances an integrated perspective of Earth’s freshwater.
