To simulate the dynamic interaction between a saline lagoon and a ground water system, a numerical model for two-dimensional, variable-density, saturated-unsaturated, and coupled flow and solute transport (saltwater intrusion by finite elements and characteristics [SIFEC]) was modified to allow the volume of water and mass of salt in the lagoon to vary with each time step. The modified SIFEC al...

Background: Drinking water from natural sources in coastal Bangladesh has become contaminated by varying degrees of salinity due to saltwater intrusion from rising sea levels, cyclone and storm surges and upstream withdrawal of freshwater. Objective: Our objective was to estimate salt intake from drinking water sources and examine environmental factors that may explain a seasonal excess of hype...

The existing knowledge regarding seawater intrusion and particularly upconing, in which both problems are linked to pumping, entirely relies on theoretical assumptions. Therefore, in this paper, an attempt is made to capture the effects of pumping on seawater intrusion and upconing using 2D resistivity measurement. For this work, two positions, one perpendicular and the other parallel to the se...

This paper deals with numerical modeling of groundwater systems. Ensuring the sustainability of an aquifer’s yield is one of the fundamental tasks for nowadays groundwater management, especially within agriculturally used regions. Within the context of the research project ”International Water Research Alliance Saxony” (Kalbus et al., 2011, submitted), the groundwater quality of near-coastal, a...

Water quality conditions have been assessed in the Río Vélez coastal aquifer (Andalusia, South Spain: an area of important agricultural and touristic development). This shallow fluvio-deltaic aquifer consists of coarse detrital deposits, of Quaternary age, that extend over about 20 km, being subdivided in two sectors –fluvial and deltaicby a substratum elevation. The deltaic sector is highly vu...

ABSTRACT The French Mediterranean coastal aquifers are essentially alluvial, deep sedimentary and karst. Whereas the alluvial aquifers are particularly sensitive to salt-water intru sion, contamination of the deep aquifers is generally due to vertical hydraulic connec tion with the shallow aquifers. As for the karst systems, which are quite well developed f rom Languedoc-Roussillon to Provence-...

This paper presents the application of a new methodology for coastal multi-hazard assessment & management under a changing global climate on the state of Karnataka, India. The recently published methodology termed the Coastal Hazard Wheel (CHW) is designed for local, regional and national hazard screening in areas with limited data availability, and covers the hazards of ecosystem disruption, g...
