Conversion of Saline Water to Fresh Water Using Air Gap Membrane Distillation (AGMD)
… (MD) is a combination of evaporation of water from saline solution and diffusion of vapour through a hydrophobic membrane. The driving force is the vapour pressure difference created by temperature difference across the membrane. With development of hydrophobic membranes at a cheaper …

Response of tall fescue to saline water as influenced by leaching fractions and irrigation uniformity distributions
… the response of tall fescue to irrigation with saline water. Tall fescue (Festuca arundinacea Schreb. 'Monarch') was grown in 18 plots, each with a centrally located lysimeter that enabled estimates of evapotranspiration and irrigation requirements. Imposed treatments included setting LFs at …

The Effect of Faults upon Ground Water Flow in the Baton Rouge Fault System
… Rouge area, which are the main source of freshwater. Beds dip and thicken toward the south. Aquifers in the Baton Rouge area are disrupted by the BRF. Aquifers contain fresh water in the updip (north of the BRF) and saline water in the downdip (south of the BRF) directions. Saline water has …

Enhancement of heat transfer coefficient using nanofluids for multi-stage flash desalination (MSF) plant
… under laminar and turbulent flow regimes, of water-based spherical Al<sub>2</sub>O<sub>3</sub>, CuO, and Fe<sub>2</sub>O<sub>3</sub> nanofluids have been experimentally investigated for the improvement of the thermal desalination processes using a newly developed sophisticated noninvasive heat …

Investigation of the impact of desalination on the salinity of the Persian Gulf
… meters per year) and far exceeds the sum of freshwater inflow to the Gulf, mainly from precipitation and some from river flow. A residual circulation exists between the Gulf and the Indian Ocean such that saline water flows into the Gulf from the Indian Ocean in order to balance the freshwater …

Foliar response of woody ornamentals to sprinkler irrigation with reuse water
… associated with sprinkle irrigation of reuse water. Reuse water, municipal water and a synthesized saline water were applied via sprinkler irrigation to 20 ornamental tree species. A visual damage index was created based on canopy and leaf level characteristics to assess damage. The index …

Geochemical Evidence for Vertical Migration of Deep Formation Fluids through the Baton Rouge -Denham Springs Fault System
<p>Accumulations of brackish groundwater exist across south Louisiana within the shallow, south-dipping Pleistocene to Upper Miocene Baton Rouge Aquifer System (BRAS). This research investigates the source of brackish groundwater through geochemical analysis of representative groundwater samples by …

Characterization and modeling of the stress and pore-fluid dependent acoustic properties of fractured porous rocks
… area for hydrocarbon exploration and production, water utilization, underground contaminant transport and waste storage, mineral extraction and geothermal energy. Seismic surveys will continue to be the backbone of subsurface characterization. This thesis study has uncovered several important …

Space-time variability of soil salinity in irrigated vineyards of South Africa
Salts present in the soil and surface waters of the Western Cape Province of South Africa represent a limitation to farming activities. Therefore the management of salinity in the landscape, which includes measuring, mapping and monitoring of its behaviour on a regional scale, is the subject of …

The role of colloidal phase in the measurement of pollutants in natural waters
The components of natural water can be divided into three categories: dissolved, colloidal and particulate phases. The colloids are small particles with at least one dimension between 1.0 nm and 1.0 µm (IUPAC); they do not sediment when suspended in “solution”. The small size of colloidal particles …

The Biology of Spaeroma Terebrans in Lake Pontchartrain, Louisiana with Emphasis on Burrowing
… in wood and marine structures of fresh to saline water. Existing literature on S. terebrans focuses on the destruction of red mangrove (Rhizophora mangle) in India, Pakistan, and Florida. This study concentrates on S. terebrans habitat and boring preferences in bald cypress (Taxodium …

Investigation of salinity and nutrient characteristics of two groundwater based flow systems on Virginia's Eastern Shore
The freshwater-saltwater transition zone was investigated in an unconfined aquifer on Virginia’s Eastern Shore. The Steelman’s Landing study site consisted of a well transect which began in an 800 meter wide upland agricultural field, and proceeded seaward through a 300 meter wide mesic forest, 300 …

Salt stress responses in pear and quince: physiological and molecular aspects
… information is available on its behavior under saline conditions. Previous studies, carried out in the Department of Fruit Tree and Woody Plant Science (University of Bologna), focused their attention on pear and quince salt stress responses to understand which rootstock would be the most …

Effects of reinforcement corrosion on the structural performance of reinforced concrete beams
… to alternate cycles of wetting and drying with a saline water. An attempt is made at classifying the extent of corrosion of the reinforcing steel and its effects on the concrete. The effect of the corrosion on the structural performance is measured by establishing its effect on the maximum load …

The geochemical evolution of saline groundwater within a fresh water aquifer south of Oakes, North Dakota
<p>An area of saline/brackish groundwater south of Oakes, North Dakota has been reported by the North Dakota State Water Commission. The concentrated water (over 12,000 mg/L of total dissolved solids) is in direct hydraulic connection with relatively fresh water and shows an abrupt change in …

Cyclic irrigation of turfgrass using a shallow saline aquifer
Utilization of poor quality waters in the urban landscape has the potential of saving large quantities of good quality water for higher priority uses. Bernudagrass in particular is well suited to be irrigated with poorer quality water. A two-year field study was conducted to determine the long-term …

Determination of evaporative flux from water and soil surfaces
The Canadian Prairies has the highest water demand-to-availability ratio in Canada. The region is characterized by a scarcity of water resources because evaporation generally exceed precipitation. Evaporation is a complex phenomenon based on interactions between meteorological and physiological …

Construction of prototype system for directional solvent extraction desalination
… desalination process. This method dissolves the water into an inexpensive, benign directional solvent, rejects the contaminants, then recovers pure water, and re-uses the solvent. In order to bring this technology closer to real world application, a continuous process prototype for a directional …
