Groundwater that drains to surface water through seeps and springs is generally referred to as “discharge.” Groundwater discharge is a primary component of stream base flow, or streamflow that occurs between storms, periods of snowmelt runoff, and periods of quick soil drainage.

Janet Barclay is a Hydrologist in the New England Water Science Center.
Janet is interested in questions about the flow of water, nutrients and pollutants in groundwater and surface water systems, and in the innovative use of data for model calibration and evaluation. Her work focuses on modeling groundwater flow, stream temperature, and surface-water and groundwater transport of nitrogen. She uses process-based models, such as MODFLOW, machine learning models, and statistical analysis.

Determining High Groundwater Levels in Massachusetts
A method (commonly referred to as the Frimpter method) was developed in early 1980’s to estimate probable high groundwater levels across Massachusetts. The map and table on the web page linked above provide information on wells in the Massachusetts Observation-Well Network which have been used as index wells.
