Introduction The climate is a complex system that encompasses numerous Earth surface systems, i.e. the atmosphere, hydrosphere, cryosphere, lithosphere, and biosphere. The preponderance of scientific evidence indicates that anthropogenic actions such as excess generation of greenhouse gases are causing serious climatic change. Water is a critical resource to humans, commerce, wildlife, and the ...

Environmental flow requirements, to maintain the functioning of freshwater-dependent ecosystems and restore rivers in ecologically acceptable conditions, depend upon the present water quality status of the river. Various stretches of Vishwamitri River vary in quality and quantity. Water quality index is a tool to converse information regarding water quality of various stretches of river and can...

Precipitation changes and urban growth are two factors altering the state of water quality. Changes in precipitation will alter the amount and timing of flows, and the corresponding sediment and nutrient dynamics. Meanwhile, densification associated with urban growth will create more impervious surfaces which will alter sediment and nutrient loadings. Land and water managers rely on models to d...

Efficiency of Flue Gas Desulfurization System (FGD) is affected by numerous technical parameters like: proper fuel preparation, quantity and quality of fuel, combustion conditions in furnace chamber, quality of flue gas corresponding to the operating conditions of FGD system, design quantity and quality of flue gas at the inlet of FGD system, design quantity and quality of used sorbent, design ...

Materials and Methods: In this descriptive-analytical study, 384 people were randomly selected from Rafsanjan City and their public environmental issues and concerns were evaluated. Th...

Water resources management is one of the most important challenges the world faces. It is difficult to think of a resource more essential to the health of human communities or their economies than water. Humans cannot live for more than several days without water, shorter than for any source of sustenance other than fresh air. In meeting their demand for water, societies extract vast quantities...

Groundwater aquifers as one of the main sources of water supplies are faced with different risks such as level dropping due to lack of precipitation, and natural and non-natural pollutants. Thus, it is extremely necessary to monitor ground water quality. In the present study, the concentration of cations, anions, and some toxic metals was evaluated in 21 rural water supplies in Qorveh plain in ...
