EFDC+ GOTM White Paper

DSI recently published a white paper detailing the integration of the General Ocean Turbulence Model (GOTM) with the Environmental Fluid Dynamics Code Plus (EFDC+). For the past three decades, EFDC has primarily relied on the renowned Mellor-Yamada level-2.5 turbulence closure scheme, which encompasses various second-moment closure methods. However, this approach has remained largely unchanged during this extended period. In a significant leap forward, EFDC+ has now incorporated various first- and second-order closure methods through its coupling with GOTM subroutines. This marks a profound enhancement to EFDC's hydrodynamic capabilities, making it the most substantial upgrade to date. To access the full paper, please click on the following link: here.

In the News: Q&A: Researcher discusses work to solve America's groundwater crisis

Beneath the roadways and sidewalks we traverse every day are underground reservoirs that supply a substantial chunk of nation's overall water needs. These groundwater aquifers once sustained America's cities and farmland. Now, according to a New York Times investigation, they could be drying up for good. Read more.
