The development of a surface water evaluation index is a critical factor in the assessment, restoration and protection of stream water quality. Quantifying water pollution in specific grade using dominant parameters is important, as this can explain the current state of water pollution with accuracy. As a result, an integrated multi-parameter water quality index has been developed. It is based ...

The article analyzes methods for the protection of reservoir water against the eutrophication process. It discusses methods for protection against point-source, spatial and dispersed pollution, biological methods and the most frequently applied technical methods. It pays special attention to the application of mathematical modelling to predict changes in water quality. A simulation of water qua...

Alternate water sources are being implemented in urban areas to augment scheme water supplied by a water utility to homes. These sources include residential wells, rainwater tanks and greywater systems. Greater water efficiency can be achieved when these systems are designed to match a water source to a given demand based on both water quantity and quality parameters. In this way the use of an ...

phytoplankton and zooplankton concentrations in pishin reservoir are predicted employing a three-dimensional numerical model in this paper. modeling is performed using a numerical model based on mass transport equation. advection, diffusion and source/sink processes are considered as separate subroutines for predicting the concentrations of phytoplankton and zooplankton in the reservoir. finite...

background: the purpose of study was to evaluate and compare chemical quality of iranian bottled drinking water reported on manufacturer's labeling and standards. methods: this study was a cross-sectional descriptive study and done during july to december 2008. the bottled mineral water collected from shops randomly were analyzed for all parameters address on manufacturer's labeling and the res...

Yarra Valley Water, a corporatised water utility achieved the significant efficiencies that are promised from the move towards privatisation. At the same time it substantially improved the quality of service delivery to its customers. It demonstrated that substantial benefits can be achieved with a minimal investment through leveraging existing information systems. The use of enterprise modelli...

The world faces critical food security issues due to the combined pressures of population growth, depletion of finite resources and uncertainty in future climate. Of particular concern is the depletion of stocks in wild fisheries, and land-based aquaculture is one response to this problem. This research will look at opportunities to engineer highly efficient, integrated food production systems ...

Preface Application of natural computing (computational intelligence) methods to water resources and environmental modelling Over the last 10 to 15 years, natural computing methods have been applied extensively to the modelling and management of our natural and built environments. Data-driven approaches, such as artificial neural networks (ANNs), have been used for prediction and forecasting an...
