The Dynamics of Sea Tide-Induced Fluctuations of Groundwater Level and Freshwater-Saltwater Interface in Coastal Aquifers: Laboratory Experiments and Numerical Modeling

Figure 5

Water levels at all four piezometers and salinities at two electrodes which are located at the same depth (#7 and #8). Locations of the electrodes are shown in Figure 1(b). Note that the salinity peaks appear ~2 minutes after the water level peaks.
