Coastal groundwater aquifers –history, risks and Management
Conveners: Kumanova & Jacks
Coastal plains are underlain by important groundwater aquifers. They are often large and have experienced a complicated history, involving tectonic movements, climate change, especially the last glaciation with large variations in sea water levels. The last glaciation is often mirrored in the hydrochemistry of the groundwater as the turnover of the groundwater is often slow in the large aquifers. The session will take up risks for salt water intrusion, interpretations using hydrochemistry and isotopes and possible management.
