Investigations of the impact on surface water/groundwater interactions using carbon-14

Abstract

Groundwater resources are increasingly being developed across the globe, particularly in arid to semi-arid regions where, in periods of drought, groundwater is heavily relied upon. Over abstraction of groundwater has the potential to impact surface water flows in these catchments. However, the processes and timescales at which this impact operates are generally poorly understood. Groundwater dating using carbon-14 can aid in the understanding of long-term surface water/groundwater interaction processes. © 2009 AINSE
