Time‐Lapse Geophysical Measurements for Monitoring Coastal Groundwater Dynamics in an Unconfined Aquifer

“…In the study area, groundwater is the only source of drinking water for the coastal communities (Cox et al 2019). There is a higher demand for groundwater in summer for two reasons: higher evapotranspiration and a seasonal influx of tourists (Wild and Nimiroski 2005). Groundwater in the study area is stored and transmitted through surficial sediments and the underlying bedrock.…”
