A multi-objective linked simulation and optimization (LSO) model for a three dimensional saltwater intrusion problem has been developed. The LSO employs HST3D and Box’s algorithm. The weighting method of multi-objective optimization solves the multi-objective planning problem. The model is capable of determining the optimal pumping rates that minimize the saline concentration at the well sites,...

Introduction: As Iran faces limited water resources, it should take the use of unconventional waters into account in its drought management. In many countries, including Iran, conventional water is relatively scarce. However, should water, soil, and plants be appropriately managed, there would be significant saline water sources for irrigation purposes. Together with reducing salinity and refin...

Salinity is a major driver of bacterial community composition across the globe. Despite growing recognition that different bacterial species are present or active at different salinities, the mechanisms by which salinity structures community composition remain unclear. We tested the hypothesis that these patterns reflect ecological coherence in the salinity preferences of phylogenetic groups us...

The efficacy of sustained release Altosid sand granules to control adult Aedes taeniorhynchus and Culex quinquefasciatus emergence was investigated. Sand granules applied at a 7-day preflood application rate of 5.6 kg/ha controlled 99% of the Ae. taeniorhynchus emergence in saltwater plots for 44 days posttreatment and 35% of Cx. quinquefasciatus in freshwater plots. A 5.6 kg/ha rate controlled...

[1] Sea level rise and reduction of groundwater fluxes due to changes in rainfall patterns are the two major climate change–induced hydrological variables that can severely affect saltwater intrusion in coastal aquifers. In this study we use a combination of laboratory experiments and numerical simulations to study the impacts of changes in one of these climate change–induced hydrological varia...

There appears to be very poor investigation of postmortem serum calcium (Ca) and magnesium (Mg) for diagnostic evidence to determine the cause of death. The aim of the present study was a comprehensive analysis of the serum levels in relation to the causes of death in routine casework. Autopsy cases (total, n=360; 5-48 h postmortem), including blunt injury (n=76), sharp injury (n=29), asphyxiat...

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...

We analyze the combined effects of aquifer heterogeneity and pumping operations on seawater intrusion (SWI) in coastal aquifers, a phenomenon which is threatening Mediterranean and worldwide regions. We conceptualize the aquifer as a three-dimensional randomly heterogeneous porous medium, where the spatial distribution of permeability is uncertain. The geological setting of our study is pattern...

The global transfer of live bait creates a potent vector (mechanism) for invasion of marine species, including associated biota (“hitchhikers”) not intended for shipment. Unlike other vectors of non-native species transfer in coastal marine systems (e.g., ship ballast water), vector management strategies to reduce transport of associated biota with live bait are lacking. In this study, we exper...
