Owing to population growth and water demand, coastal aquifers all over the world are over–pumped, resulting in serious problems such as saltwater intrusion. So, in these conditions, assessing the groundwater system’s vulnerability and finding areas with saltwater intrusion potential are vital for the better management of aquifers. In this study, AHP-GALDIT was applied to saltwater intrusion vul...

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...

The Vietnamese Binh Thuan province located along the Southern Central part of coast is one driest in country. population relying largely on groundwater for irrigation, and resources are threatened by climate change saltwater intrusion river estuaries. Recent studies, however, reveal that extension intrusions was larger than expected, raising some doubts actual origin intrusions. In this study, ...

Linked simulation-optimization (S/O) approaches have been extensively used as tools in coastal aquifer management. However, parameter uncertainties seawater intrusion (SI) simulation models often undermine the reliability of derived solutions. In this study, a stochastic S/O framework is presented and applied to real-world case Longkou China. The three conflicting objectives maximizing total pu...

Nitrogen flux into the coastal environment via submarine groundwater discharge may be modulated by microbial processes such as denitrification, but the spatial scales at which microbial communities act and vary are not well understood. In this study, we examined the denitrifying community within the beach aquifer at Huntington Beach, California, where high-nitrate groundwater is a persistent fe...

This paper describes a Geographic Information System (GIS)-based method of estimating the water balance as applied to a coastal aquifer near Bowen, Queensland, Australia, using the ten interactive steps in development and evaluation of environmental models of Jakeman et al. [2006]. The 220 km Bowen irrigation area is data-rich with 260 observation bores plus stream gauging, metering of irrigati...

To investigate the role of the seepage zone in transport, chemical speciation, and attenuation of nitrogen loads carried by submarine groundwater discharge, we collected nearshore groundwater samples (n 5 328) and examined the distribution and isotopic signature (d15N) of nitrate and ammonium. In addition, we estimated nutrient fluxes from terrestrial and marine groundwater sources. We discuss ...

The natural and pumping-induced controls on groundwater salinization in the coastal aquifers of North Carolina, USA, and the implications for the performance of a reverse osmosis (RO) desalination plant have been investigated. Since installation of the well field in the Yorktown aquifer in Kill Devil Hills of Dare County during the late 1980s, the groundwater level has declined and salinity of ...
