Short summary
Fresh groundwater can flow to oceans and seas, possibly adding nutrients and pollutants to coastal ecosystems. For the first time, three complementary (salinity-sensitive) geophysical methods are combined to delineate the outflow in a very dynamic coastal environment. This provides temporal and spatial information on the salt- and freshwater distribution on land, in the intertidal zone, and offshore and visualizes the fresh-groundwater discharge around the low-water line at De Westhoek, Belgium.
