Abstract
A recently developed slim and flexible electromagnetic (EM) borehole logging tool has been used to further monitor the development of a freshwater lens in tidal creek deposits upon artificial groundwater recharge. The monitoring is an extension of the field experiment described by Pauw et al. (2015), which was aimed at increase the freshwater lens to increase freshwater supply. The EM borehole logging tool, called the Slimflex, can be utilized up to small, 1-inch observation wells (in case properly installed). The results of the monitoring indicate ongoing freshening as a result of the artificial recharge. The speed of the freshening is lower compared to the numerical groundwater model results. This can be attributed to the presence of low-permeable clay lenses in the subsurface.
