Tide-induced groundwater fluctuation in a coastal leaky confined aquifer system extending under the sea
This paper presents the analytical solution of groundwater response to tidal fluctuation in a coastal multilayer aquifer system consisting of a leaky confined aquifer, a semipermeable layer, and an unconfined aquifer. The semipermeable layer, or the roof of the leaky confined aquifer, extends under the sea. Comparisons are made with solutions derived previously, which considered only a single a...
متن کاملInfluence of the tide on the mean watertable in an unconfined, anisotropic, inhomogeneous coastal aquifer
For an isotropic, homogeneous coastal aquifer, previous studies [Aust J Phys 26 (1973) 513; Water Resour Res 17 (4) (1981) 1222] have found that the mean watertable is influenced by the sea tide and will stand considerably above the mean sea level even in the absence of net inland recharge. This paper investigates the influence of the tide on the mean watertable for the case that the unconfined...
متن کاملConservative identification of nodal transmissivities: theory, computational experiments and application to the Rharb coastal aquifer (Morocco)
In order to calculate the transmissivity from the inverse problem corresponding to the groundwater flow in an isotropic horizontal aquifer, a numerical conservative approach is tested. The method deals with triangulation of the domain and applies the conservation of mass to elements of the mesh using the harmonic mean for internodal transmissivities. An optimal sweeping algorithm is used to eva...
متن کاملTide-induced seawater–groundwater circulation in a multi-layered coastal leaky aquifer system
Mean groundwater levels of a multi-layered coastal leaky aquifer system are considered. The system consists of an unconfined aquifer, a confined aquifer and a semi-permeable layer between them. Both exact asymptotic solutions and approximate perturbation solutions are derived for multi-sinusoidal-component sea tide. At inland places far from the coastline, the perturbation solutions show a good...
متن کاملInvestigation of the management scenarios for the aquifer recovery using mathematical modeling (Case study: Abarkuh aquifer)
Ground waters are considered as substantial water resources in many parts of the world especially in arid and semi-arid area such as Iran. The population growth, the intensive use ofsurface water and groundwater resources has often affected ground water levels. To meeting water management objectives it is essential to have a comprehensive study on the aquifer recharge and ground water withdrawa...
