USGS scientists create and apply computer programs to simulate or forecast groundwater flow conditions over time. Although groundwater and surface water are considered a single resource, many hydrologic models don't fully simulate the connections between groundwater systems and other hydrologic processes. USGS recently constructed a groundwater/surface-water model for the Black Earth Creek watershed in south-central Wisconsin using the computer code GSFLOW (Groundwater/Surface-water FLOW) to simulate hydrologic processes in the atmosphere, at land surface, in streams, within the soil zone, and in groundwater on a daily time step during water years 1985-2007. The model was then run to simulate scenarios representing common societal concerns in the basin, focusing on maintaining a cold-water resource in an urbanizing fringe near the upper stream reaches of Black Earth Creek and minimizing downstream flooding. Learn more about the project in the new report, Simulation of climate change effects on streamflow, groundwater, and stream temperature using GSFLOW and SNTEMP in the Black Earth Creek Watershed, Wisconsin Scientific Investigations Report 2016-5091.

Field Photo: Scientists Never Stop Learning
For USGS scientists, learning doesn't stop when we leave school. We are constantly learning -- new tools, new scientific methods, and new science. Recently a group of USGS scientists took a a field class to learn more about groundwater and surface-water exchange at Lake Tahoe, California. USGS hydrologists are studying Lake Tahoe to gain an understanding of heat and nutrient transport through Lake Tahoe's shoreline environments. Participating scientists got a chance to see and try a variety of scientific instruments being used as part of this and related studies, including the broadband electromagnetic induction tool shown in the first photo below, demonstrated by USGS hydrologist Eric White. In the bottom photo below, USGS research hydrologist Ramon Naranjo introduces scientists to one of the field sites.
