Climate-Groundwater-Surface Water Interrelationships Over the South Eastern US

This research focuses in understanding the interaction between climate, groundwater and surface water over the Southeastern US. For this purpose, we consider observed streamflow, precipitation, temperature and groundwater levels from twenty basins from the USGS climate-groundwater network. Seasonality analyses on the four variables indicate both high and low periods of activity for each variable. Singular spectrum analyses on all the four variables indicate that groundwater is the most dominant component in explaining the first component. Relating eigen values with drainage area show that large basins exhibit increased role for groundwater. Analyses on relating precipitation forecasts and sea surface temperature conditions show that there is a potential in predicting groundwater availability purely based on climate information.
