A drying machine is a that used to dry some food or product. The process of heating can be preserve products because reduces moisture content in the product and bacterial can’t live without water. Solar pond system will use for which caught trap heat from sun. fluid solar saltwater salinity varied. variation 3.5%, 5%, 7%. In system, coils circulate water towards cabin. coil made copper pipe has...

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...

The accumulation of sediment in aquatic environments can lead to an increase flood risk due raised floodplains and water levels. Electromagnetic modeling techniques, such as Time Domain (TDEM) resistivity or lithological conductivity contrast, be utilized detect changes the subsurface. In this study, we investigated use TDEM hazard mitigation schemes by developing a 1-D forward program for cent...

freshwater lens on small islands may easily be overexploited or polluted due to overdrafts of fresh water by pumping which causes drawdown of the water table a rise or up-coning of the saltwater interface. present study is concerned with using a three-dimensional finite-difference numerical model to simulate the groundwater flow and transport model to predict the behavior of groundwater system ...

Most salmonid taxa have an anadromous life history strategy, whereby fish migrate to saltwater habitats for a growth period before returning to freshwater habitats for spawning. Moreover, several species are characterized by different life history tactics whereby resident and anadromous forms may occur in genetically differentiated populations within a same species, as well as polymorphism with...

The site under study covers an area of 273 km in the Oristano plain on the west coast of Sardinia (Italy). Since 1950 the plain, formed during the Quaternary by alluvial deposits, has been under intensive cultivation and is an important dairy farming centre. In the coastal region, the large number of wells (25,000 tapped and not) some very close to each other, has resulted in over-exploitation ...
