A solution for the head distribution in a tidal leaky confined aquifer system extending a finite distance under the sea
XVI International Conference on Computational Methods in Water Resources
2006
2006
Consider a coastal aquifer system with an unconfined aquifer, a leaky aquifer, and
an aquitard between them. An new analytical solution is developed to investigate
the effects of tidal fluctuations and leakage on the groundwater head of leaky
confined aquifer extending a finite distance under the sea. The tidal fluctuations
in both unconfined and leaky aquifers are considered. The leakage of the offshore
aquitard, which may be formed by sedimentary depositional process of the offshore
current, is assumed different from that of the inland aquitard. All the existing
solutions regarding the investigation on the head distribution for a leaky confined
aquifer may be regarded as special cases of our solution. Based on this newly
derived solution, we will investigate the dynamic effects between the leaky and
unconfined aquifers in response to the tide. In addition, some hypothetical cases
will be used to explore the influences of offshore and inland leakages on the tidal
fluctuation in a leaky aquifer.
