Abstract Laboratory scale experiments and numerical modelling were employed in this study to investigate saltwater intrusion fractured aquifers. Saline was initiated one homogeneous six experimental aquifers containing individual discontinuities of varying length orientation. Automated image processing enabled high precision quantification three variables, the toe saline wedge, width mixing zon...

A geophysical study carried out in the framework of water resources recognition within Essaouira coastal area (Morocco) enabled to outline spatial distribution Plio-Pleistocene and Cretaceous formations. It helped determine thickness extension main aquifer used for irrigation purpose. The overall aim this is highlight hydrogeological structures Basin. total 45 vertical electrical soundings (VES...

Abstract We are solving a problem of salinisation coastal aquifers. As test case example, we consider the Henry saltwater intrusion problem. Since porosity, permeability and recharge unknown or only known at few points, model them using random fields variables. The describes two‐phase flow is non‐linear time‐dependent. solution to be found expectation salt mass fraction, which uncertain To esti...

Aquifers are of particular interest in the vicinity rivers, lakes and coastal areas due to their extensive usage. Hydraulic properties such as transmissivity storativity can be deduced from periodical water level fluctuations both open bodies groundwater. Here, we model effect complex wave propagation into adjacent isotropic homogeneous aquifers. Besides confined aquifers, also study leaky aqui...

Geochemical evaluation of the sources and movement of saline groundwater in coastal aquifers can aid in the initial mapping of the subsurface when geological information is unavailable. Chloride concentrations of groundwater in a coastal aquifer near San Diego, California, range from about 57 to 39,400 mg/L. On the basis of relative proportions of major-ions, the chemical composition is classif...

Ground water samples (37 to 186 m depth) from Baldwin County, Alabama, are used to define the hydrogeology of Gulf coastal aquifers and calculate the subsurface discharge of nutrients to the Gulf of Mexico. The ground water flow and nitrate flux have been determined by linking ground water concentrations to 3H/3He and 4He age dates. The middle aquifer (A2) is an active flow system characterized...

Tidal fluctuations in a leaky confined coastal aquifer are damped significantly due to leakage into an overlying phreatic aquifer. Jiao and Tang [1999] presented an analytical solution to a simple model describing this phenomenon. Their solution assumes that the tidal fluctuations in the overlying phreatic aquifer are negligible (i.e., a static phreatic aquifer). Here we examine dynamic effects...

This paper analyzes and summarizes the numerous types of variations of groundwater pressures (heads), mid-oceanic ridge borehole temperatures and microseismicity in response to tidal forcing in coastal aquifers and deep sea sediments. Tidally related data obtained from various sources were filtered and processed by means of classical harmonic analysis to extract the amplitudes of pressure and t...

Despite its purported importance, previous studies of the influence of sea-level rise on coastal aquifers have focused on specific sites, and a generalized systematic analysis of the general case of the sea water intrusion response to sea-level rise has not been reported. In this study, a simple conceptual framework is used to provide a first-order assessment of sea water intrusion changes in c...
