Available in PDF, EPUB and Kindle. Book excerpt: A computer model is presented that simulates the movement of an interface separating two incompressible fluids: fresh and salt groundwater. The technique is a modification of the method of modeling interface movement by the use of distributed singularities originally presented by De Josselin de Jong. The modifications consist of: 1. formulating the problem in terms of potentials rather than velocities (applicable only for piecewise constant densities), 2. using complex variable methods to implement boundary conditions. The problem is solved by treating the flow as quasi-steady. A boundary value problem is solved at selected times and the convection of the interface is determined by interpolation of the velocities, which are determined by analytic differentiation of the complex potential function. A Hele-Shaw model was constructed to verify the shape of the interface and movement with time as predicted by the computer model.

Available in PDF, EPUB and Kindle. Book excerpt: Coastal aquifers serve as major sources for freshwater supply in many countries around the world, especially in arid and semi-arid zones. Many coastal areas are also heavily urbanized, a fact that makes the need for freshwater even more acute. Coastal aquifers are highly sensitive to disturbances. Inappropriate management of a coastal aquifer may lead to its destruction as a source for freshwater much earlier than other aquifers which are not connected to the sea. The reason is the threat of seawater intrusion. In many coastal aquifers, intrusion of seawater has become one of the major constraints imposed on groundwater utilization. As sea water intrusion progresses, existing pumping wells, especially those close to the coast, become saline and have to be abandoned. Also, the area above the intruding seawater wedge is lost as a source of natural replenishment to the aquifer. Despite the importance of this subject, so far there does not exist a book that integrates our present knowledge of seawater intrusion, its occurrences, physical mechanism, chemistry, exploration by geo physical and geochemical techniques, conceptual and mathematical modeling, analytical and numerical solution methods, engineering measures of combating seawater intrusion, management strategies, and experience learned from case studies. By presenting this fairly comprehensive volume on the state-of-the-art of knowledge and ex perience on saltwater intrusion, we hoped to transfer this body of knowledge to the geologists, hydrologists, hydraulic engineers, water resources planners, managers, and governmental policy makers, who are engaged in the sustainable development of coastal fresh ground water resources.

Available in PDF, EPUB and Kindle. Book excerpt: The modeling of groundwater in costal aquifers is an important and difficult issue in water resources. The primary difficulty resides in efficient and accurate simulation of the movement of the saltwater front. This thesis is devoted to the sharp interface numerical study of one and two dimensional of seawater intrusion into coastal aquifers. The Finite Volume method is adopted here to solve the set of simultaneous diffusion differential equations describing the motion of saltwater and freshwater separated by a sharp interface. These diffusion equations are based on the Dupuit approximation and are obtained from integration over the vertical dimension. The one dimensional Finite Volume model is first being validated using academic test case studies with known close from solutions. The second purpose of this study is to compare two dimensional numerical methods, Finite Volume method and Sharp model based on Finite Difference method when applied to a Llobregat aquifer, in Barcelona, Spain. Both methods are using the same mathematical formulation for the sharp interface. The comparison between both methods indicates that Finite Volume method provides predictions closer to the observed results.

None of them at present in any immediate danger of saltwater contamination, however, with furthur groundwater development the risk will escalate. Based on the Galerkin finite element technique the study predicts the piezometric declines and saltwater movement in the multilayered aquifer system at Tanjung Mas, Kelantan using a 2-dimensional fresh-saltwater interface model.[Authors' abstract].

This book was released on 2004-01-01 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This is a Ph.D. dissertation. Groundwater aquifers are an important resource in coastal regions. In many areas where there is no fresh surface water from rivers or reservoirs, the development of ground water resources is practically the only alternative to storage of rainwater. However, the coastal aquifers are very vulnerable to the seawater intrusion through the overdraft of groundwater exploitation or insufficient recharge from upstream, etc. In order to control sea water intrusion, varying forms of saltwater intrusion management models have been studied. They address the optimal ground water pumping and recharge schedules with or without surface water supplies for conjunctive use. Contents include: Introduction, Literature Review, The Response of Saltwater Intrusion Lengths with Respect to the Stresses and Transmissivities - Sensitivity Analysis Based on the SHARP Computer Code, Conic Quadratic Programming, Development of the Methodology for the Multi-Objective Saltwater Intrusion Management Model, Hypothetical Example Results for the Quasi-Three-Dimensional SHARP Model Simulation of a One-Layered Aquifer, The Results of the Real-World Case Application, Conclusions and Recommendations."
