The Henry Problem for Saltwater Intrusion
Water Resources Research, 1995Previous solutions of the idealized saltwater intrusion problem known as the Henry problem are discussed, and possible reasons for the observed discrepancies between them are given. High‐accuracy finite difference techniques are used to solve the nondimensionalized equations governing the problem, and a fine grid is used so that the solutions obtained ...

Effect of saltwater intrusion on activated sludge flocculation
Water Environment Research, 2020AbstractSaltwater addition negatively impacted the settling properties of the activated sludge in a sequencing batch reactor, which in turn caused the effluent quality and the dewatering properties to deteriorate. Experiments showed that increasing sodium ion concentrations above 1 meq/L interfered with bio‐flocculation by ion exchange of calcium ions ...

Saltwater intrusion in a subtropical estuary
Estuarine, Coastal and Shelf Science, 2019Abstract River discharge, precipitation, wind, water level and salinity measurements were used to investigate saltwater intrusion in a subtropical estuary. The upstream limit of saltwater intrusion was defined by the position of the 2 g/kg isohaline ( X 2 ) as it changed each tidal cycle.

Coastal Aquifers and Saltwater Intrusion
2008As a large portion of the world's population (e.g. about 70%) dwells in coastal zones, sustainable and optimal coastal aquifer exploitation that controls saltwater intrusion is necessary. Especially in coastal zones, groundwater over- exploitation has disturbed the naturally established equilibrium between saltwater and freshwater which has resulted in

Saltwater Intrusion in the United States
Journal of the Hydraulics Division, 1969The occurrence of saline water is described in terms of geologic and hydrologic conditions. The three general mechanisms of intrusion are considered.

Geophysical Methods Applied to Saltwater Intrusion in Antigua
Symposium on the Application of Geophysics to Engineering and Environmental Problems 2004, 2004The island of Antigua has been suffering from an acute shortage of potable water due largely to drought conditions on the island. Because of the persistent drought conditions one of the island's primary sources of potable water, the Potworks Dam, is dry. In addition to the Potworks Dam, the nearby smaller Collins Dam is also dry.

Types of saltwater intrusion of the Changjiang Estuary
Science in China Series B: Chemistry, 2001The Changjiang Estuary is characterized by multi-order bifurcations, unsteady sub-merged sandbars, mid-channel sandbars, creeks and riffles. The following four types of saltwater intrusion are found: (1) direct intrusion from the sea; (2) intrusion during tidal flooding; (3) intrusion from tidal flats overflow; and (4) salt water coming upstream ...

Saltwater Intrusion Hydrodynamics in a Tidal Aquifer
Journal of Hydrologic Engineering, 2008The saltwater freshwater interface at the intertidal zones of surficial aquifers is continuously influenced by tidal effects. The numerical solution of this continuously changing intertidal saltwater interface profile is difficult. To simulate this dynamic system correctly appropriate definition and use of seaside boundary conditions are necessary. The

Saltwater intrusion in the Mekong Delta
The Mekong Delta is affected by annual seasonal salinity intrusion in December–May. In this season, the discharge of the Mekong is low, and high tidal water levels cause a deep intrusion of saline water. Critical salt concentrations can be observed 50–80 km deep during high tides.Apel, H. +3 more

Dispersion Process and Saltwater Intrusion in Groundwater
2000Dispersion phenomena of solutes and pollutants (contaminants/tracers) in subsurface water and porous media have caught the interest of researchers since the 1960s. The mathematical formulation of problems in terms of hydraulics has been realized by applying mass conservation (including source or sink terms for dispersed matter), Fick’s law and ...
