| Zusammenfassung |
| In the past, the coastal leaky aquifer system, including two aquifers and an
aquitard between them, was commonly assumed to be homogeneous and of
infinite extent in the horizontal direction. The leaky aquifer system may
however be heterogeneous and of finite extent due to variations in
depositional and post depositional processes. In this paper, the leaky
aquifer system is divided into several horizontal regions for the
heterogeneous aquitard and underlying aquifer. A one-dimensional analytical
model is developed for describing the head fluctuation in such a
heterogeneous leaky aquifer system. The hydraulic head of the upper
unconfined aquifer is assumed constant. It is found that both the length and
location of the discontinuous aquitards presented in the coastal area have
significant effects on the amplitude and phase shift of the head fluctuation
in the lower aquifer. In addition, the influence of the formation
heterogeneity on the spatial head distribution is also investigated. |
