Heavy metal pollution dispersion simulation in rivers and predicting spatial and temporal variations of pollutants can be used to determine the precise place and to schedule water withdrawal time for drinking, agriculture, aquaculture and ecosystem studies. To study the movement of heavy metal pollution through Karoon flow model, MIKE 11 was employed fpr simulation of the flow model of Karoon R...

Abstract The management of water resources requires a correct understanding the simultaneous food and energy resources. framework water–food–energy correlation with approach sustainability uses analyzes combined exploitation water, food, help scenario planning. In addition to concepts, environmental costs such as emission carbon dioxide from fossil fuels its impact on environment are also discu...

protein based films used for food packaging despite having numerous benefits like biodegradability and renewability suffer from essential drawbacks of weak mechanical and water vapour barrier properties. in recent years efforts for improving functional properties of such films from various resources, through modifying formulation, molecular crosslinking and promote proteins based composite film...

wetlands are ecosystems with specific features and functions which have been unfortunatelydamaged by recent pressures and limitations. fast reduction of surface flows, water and wind erosion of soil,changes in the quality of water and soil resources, increasing exploitation of underground water, agriculturaldevelopment, climate change, etc. have had the most effect on these ecosystems. so this ...
