Groundwater-to-atmosphere Simulations Including Human Water Use at the Continental Scale

2017 Fall Cyberseminar Series

Stefan Kollett / Research Center Jülich and Bonn University

Talk Description:

In the webinar, we will take a tour from groundwater across the land surface into the atmosphere inspecting important interfaces, and how these interfaces are treated theoretically and technically in coupled models of the terrestrial water and energy cycle. The human impact with regard to groundwater pumping and irrigation will be introduced, adding even more complexity to an already extremely intricate biogeophysical problem. Major challenges and simplifying assumptions will be discussed that are a prerequisite for interpreting simulation results and assessing uncertainty. Our tour will serve as the basis for introducing the Terrestrial Systems Modeling Platform (TerrSysMP) including simulation examples, which demonstrate the importance of closing the terrestrial water and energy cycle from groundwater into the atmosphere.

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.
