Saltwater intrusion is one of the most severe problems for worldwide coastal regions, leading to negative impacts on both human and aquatic inhabitant communities. Quang Tri province, located in Central Coast region Vietnam, faces consequences saltwater because its dense river network El Nino phenomena’s influences. To analyse hydrological, hydraulic processes as well investigate intrusion’s si...

The bioavailability and toxicity of copper (Cu) in Shelter Island Yacht Basin (SIYB), San Diego, CA, USA, was assessed with simultaneous toxicological, chemical, and modeling approaches. Toxicological measurements included laboratory toxicity testing with Mytilus galloprovincialis (Mediterranean mussel) embryos added to both site water (ambient) and site water spiked with multiple Cu concentrat...

Abstract Laboratory scale experiments and numerical modelling were employed in this study to investigate saltwater intrusion fractured aquifers. Saline was initiated one homogeneous six experimental aquifers containing individual discontinuities of varying length orientation. Automated image processing enabled high precision quantification three variables, the toe saline wedge, width mixing zon...

protection of water resources from contamination and detection of the contaminants and their treatments are among the essential issues in the management of water resources. in this work, the time-lapse electrical resistivity tomography (ert) surveys were conducted along 7 longitudinal lines in the downstream of the latian dam in jajrood (iran), in order to detect the contamination resulting fro...

This article deals with the quantification of saltwater upconing below horizontal wells in freshwater lenses using analytical solutions as a computationally fast alternative to numerical simulations. Comparisons between analytical calculations and numerical simulations are presented regarding three aspects: (1) cyclic pumping; (2) dispersion; and (3) finite horizontal wells in a finite domain (...

Adult hawksbill turtles (Eretmochelys imbricata) are typically described as open-coast, coral reef and hard substrate dwellers. Here, we report new satellite tracking data on female hawksbills from several countries in the eastern Pacific that revealed previously undocumented behaviour for adults of the species. In contrast to patterns of habitat use exhibited by their Caribbean and Indo-Pacifi...
