The purpose of the numerical model is to simulate the coupling process of pressure head variations and soil deformation in each layer of the multilayer aquifer system subjected to hydraulic head variations in the pumped layer, which is located in confined aquifer II as shown in Figure 1.
Periodic changes in Earth tides cause aquifers to expand or contract, resulting in fluctuations in pore fluid pressure, leading to corresponding fluctuations of the water level in wellbores connected to confined aquifers (Hsieh et al., 1987).
The investigation was carried out on the confined aquifer of the Montalto Uffugo (Italy) test field.
The rain could hardly percolate into the confined aquifer. Well depth and well construction were investigated by the well owner, and the longitude and latitude were recorded by GPS on site.
