Analytical Solutions for Groundwater Response to Earth Tides in Thick Semiconfined Aquifers
Water Resources Research, Volume 61, Issue 1, January 2025.Abstract The tidal behavior of a well in semiconfined aquifers can be described by a diffusion equation including a leakage term. This approach is valid for thin aquifers, as long as the aquitard has low permeability relative to the aquifer. However, in cases where the aquifer is thick and the permeability of the aquitard is not low, using the existing
