Seawater Intrusion Extraction Barrier
Journal of the Irrigation and Drainage Division, 1972An experimental extraction-type sea water intrusion barrier was tested near Oxnard in Ventura County, California, to develop information on halting intrusion in the area and in other areas with similar hydrologic and geologic conditions. Major facilities of the barrier were 5 extraction wells, 25 piezometers, one anode well for cathodic protection, and

Numerical Modeling of Seawater Intrusion
1987The conceptual and mathematical models for seawater intrusion are presented in Chapter 7. In this chapter, two numerical models are presented for the analysis of groundwater flow in an aquifer saturated with two fluids (e.g., fresh and salt water), separated by a sharp interface.

Geophysical Characterization of Seawater Intrusion In Antigua, West Indies
18th EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems, 2005The Inter-American Agency for Cooperation and Development is currently funding a project focused on groundwater management in coastal karst environments in the Caribbean. The islands of Jamaica, Antigua, and Barbados are currently the primary regional participants in this project.

Mathematical Analysis of a Seawater Intrusion Model Including Storativity
SIAM Journal on Mathematical Analysis, 2017Summary: This paper is devoted to a seawater intrusion model in free aquifers, including rock and fluid compressibility effects. This original model is based on the superimposition of a phase-field model on sharp front tracking. It leads to the analysis of a two-dimensional strongly coupled system of PDEs of parabolic type describing the evolution of ...

Turbidity and seawater intrusion in Laguna de Bay
Environmental Monitoring and Assessment, 1991The ecological role of seawater intrusion in Laguna de Bay is assessed due to the operation of the Napindan Hydraulic Control Structure (NHCS). Turbidity is recognized as one limiting factor in the lake's biological productivity. Hence, to stop the natural backflow of seawater to Laguna de Bay removes one important contributory factor in facilitating ...

Hydrochemical indexes of seawater intrusion and comprehensive judgement on intrusive degree
Chinese Geographical Science, 1999The paper discusses the use of five hydrochemical indexes in evaluating seawater intrusion, and ranking the intrusion degree for Cl−, M, Br−, rHCO3/rCl and SAR. The fuzzy mathematical comprehensive judgement model has been adopted as the method of adjustment. Based on more than 300 water samples obtained from four typical profiles in the coastal region

Subsurface Seawater Intrusion Barrier Analysis
Journal of Hydraulic Engineering, 1987Seawater intrusion barriers are currently being constructed in the coastal aquifers of Japan based on the results of a computer model employing finite difference numerical techniques. This model provides a practical design and management tool for predicting the likelihood of seawater intrusion through a semipervious subsurface barrier in an unconfined ...

Optimization modelling for seawater intrusion management
Journal of Hydrology, 2014Summary The coastal aquifers of the world are facing environmental problem of seawater intrusion. This problem is the results of indiscriminate and unplanned groundwater exploitation for fulfilling the growing need of freshwater for the burgeoning global population.

Processes of seawater intrusion into river mouths
Water Resources, 2013Types, factors, as well as the environmental and economic impacts of a dangerous hydrological phenomenon, i.e., intrusion of salt or brackish sea water into river mouths, are discussed. The main theoretical and empirical approaches used in studying this phenomenon are described.

Seawater intrusion length in stratified estuaries
Water Research, 1970Abstract The determination of sea-water intrusion length in stratified estuaries is very important for the solution of some estuary problems. Existing relationships for the matter do not give satifsactory results. The factors which govern the sea-water intrusion length, the estuary parameters, are evaluated and principals to estimate the length ...
