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

Figure 6

Vertical time lag. Upper water content sensor (WC1) lags behind the lower water content sensor (WC2), and they both lag behind the sea level fluctuations. Salinity at the FSI (electrode 28, whose location is shown in Figure 1(b)) lags behind both water content sensors. These three sensors align vertically.
