abstract given the importance of environmental cycles had led to allocation of water-right for water species and ecosystems which is known as environmental flow or in stream flow. from among the various methods for estimating environmental flow, building block approach is considered as a very powerful tool for estimating the water needs. in this paper, beside simplifying the building block appr...

A highly luminescent freestanding film composed of the quantum cluster, Au(15), was prepared. We studied the utility of the material for specific metal ion detection. The sensitivity of the red emission of the cluster in the composite to Cu(2+) has been used to make a freestanding metal ion sensor, similar to pH paper. The luminescence of the film was stable when exposed to several other metal ...

Types of land disposed residuals from selected metal smelting and refining industries are described, as are the origin and disposition of land disposed residuals from the primary copper industry as an example. Quantities of land-disposed or stored residuals, including slags, sludges, and dusts, are given per unit of metal production for most primary and secondary metal smelting and refining ind...

BACKGROUND In the past 25 years, China has experienced remarkable economic growth and rapid agricultural-to-industrial and rural-to-urban transitions. As a consequence, China now faces many daunting environmental challenges that are significantly affecting human health and quality of life, including indoor and outdoor air pollution, water pollution, deforestation, loss of agricultural land, and...

In recent years, water quality degradation associated with rapid socio-economic development in the Taihu Lake Basin, China, has attracted increasing attention from both the public and the Chinese government. The primary sources of pollution in Taihu Lake are its inflow rivers and their tributaries. Effective water environmental management strategies need to be implemented in these rivers to imp...

The environmental requirement of the river is the amount of water to maintain natural ecological conditions and health of quality of the river water. In this study, to estimate the environmental water requirement of Karoun River, Dez, Great Karoun and Beheshtabad sub-basin (upper Karoun) using hydrological Montana method and offers based on frequency analysis of hydrological flow normally and u...

The objective of the Commonwealth’s Environmental Flows Initiative (EFI) was to assist state and territory water resource agencies meet the COAG Water Reform requirements for making environmental water allocations. The NT received support due in part to the focus on water resource development shifting to Northern Australia and the concurrent lack of understanding about tropical water resources ...
