Abstract During the past few years, number of regional and national assessments groundwater quality in regard to saltwater intrusion coastal aquifers has increased steadily. However, most international literature on is focused plains with unconsolidated material. Case studies, modelling approaches parameter studies dealing those systems are abundant. While hydrogeology fractured rock been inten...

Methods employed by Australian quarantine officers to control Aedes mosquitoes in containers were tested against all stages of Aedes aegypti. Saltwater emersion killed all larvae but not pupae or eggs that were briefly exposed. Swimming pool chlorine, methyl bromide fumigation, and permethrin (2% active ingredient) spray provided 100% mortality of eggs, larvae, and pupae. Aerosol sprays incorpo...

This article presents an experiment designed to test the reliability of the benefit function transfer approach using contingent valuation methods. The experiment uses data collected from anglers surveyed across eight contiguous Texas Gulf Coast bay regions over three distinct time periods. Results indicate that the benefit function transfer approach tends to over-estimate benefits, implying tha...

In this paper, a saltwater intrusion model, in view to study the dynamics of interface between and freshwater coastal aquifer, is established. This dynamic caused by an injection pumping through well located given position. From flow model each phase, we defined appropriate hypothesis obtain our global based only on height interface. The numerical simulation led us effect parameters some empiri...

measuring salinity of water at different depths along six transacts at the mouth of the wetland and along five tributaries connecting the wetland to the sea the extent of caspian sea penetration into anzali wetland was determined. the results demonstrated a depth-dependent salinity gradient extending up to 10 kilometres into the wetland. a pattern of saltwater and freshwater interface is presen...

Freshwater mussels are mollusks-close relatives of clams, oysters, and saltwater mussels. Many species of freshwater mussels can live for 20 to 30 years, and individuals of some species live for more than 100 years. Freshwater mussels have been valued by humans throughout history. They can produce pearls, and their shells can be used to make buttons for clothing or to serve as seedstock for the...
