Current urban water management practices aim to remove stormwater and wastewater efficiently from urban areas. An alternative approach is to consider stormwater and wastewater as a potential resource substitute for a portion of the water imported via the reticulated supply system. A holistic view of urban water resources provides the framework for the evaluation of the demand for water supply, ...

The purpose of this paper is multi-objective optimization of refrigeration cycle by optimization of all components of the cycle contains heat exchangers, air condenser, evaporator and super-heater. Studied refrigeration cycle is compression refrigeration cycle of unit 132 Third refineries in south pars that provide chilled water for cooling refinery equipment's. Cycle will be performed by t...

AMERICAN METEOROLOGICAL SOCIETY | 1743 T he transport and transformations of water substance in the global water cycle are of fundamental and primary importance for understanding the ecosystems, the land surface hydrology that supports them, and the management of water resources for humans. Th e water cycle is also critical for predicting weather, and the long-term climate balance of the planet...

Global warming accelerates water cycle with features of regional difference. However, little is known about the physical mechanism behind the phenomenon. To reveal the links between water cycle and climatic environment, we analyzed the changes of water cycle elements and their relationships with climatic and environmental factors. We found that when global warming was significant during the per...

lead and zinc production is one of the main predisposing factors of excessive greenhouse gases emissions, air pollution and water consumption. in this paper, the environmental problems of lead and zinc production in calcimin plant are expressed and life cycle assessment of this plant is assessed. the data regarding the amount of induced global warming and pollution, acidification, and depletion...

Abstract Rewilding is a radical approach to landscape conservation that has the potential help mitigate flood risk and low flow stresses, but this remains largely unexplored. Here, we illustrate nature of hydrological changes rewilding can be expected deliver through reducing or ceasing land management, natural vegetation regeneration, species (re)introductions, river networks. This includes ma...
