Emerging as the mainstream of VLSI design, ASIC (ApplicationSpecific Integrated Circuit) technology is revolutionizing the design, manufacturing, and marketing practices in electronicsrelated industries [1]. Ground water is one of the important resource of water. In our country most of the people are depend upon it to fulfil their daily needs [2]. Since we have limited fresh water resources thu...

Uncertainty analysis for model simulations is assuming a growing importance in the field of water quality management. The importance of this concern is provided by recent public awareness over health risks from improper disposal of toxic wastes as well as by the continuing emphasis on risk assessment. The first step in the chain of the risk assessment is the quantification of the error in predi...

Successful river water quality modelling requires the specification of an appropriate model structure and process formulation. Both must be related to the compartment structure of running water ecosystems including their longitudinal, vertical, and lateral zonation patterns. Furthermore, the temporal variability of abiotic boundary conditions may be important and must be incorporated by an appr...

In recent years health risks associated with the non-compliance of bathing 12 water quality have received increasing worldwide attention. However, it is 13 particularly challenging to establish the source of any non-compliance, due to the 14 complex nature of the source of faecal indicator organisms, and the fate and delivery 15 processes and scarcity of field measured data in many catchments a...

Water is a critical issue in China for a variety of reasons. China is poor of water resources with 2,300 m(3) of per capita availability, which is less than 13 of the world average. This is exacerbated by regional differences; e.g. North China's water availability is only about 271 m(3) of per capita value, which is only 125 of the world's average. Furthermore, pollution contributes to water sc...

In this paper results of a water quality modelling framework for riverine shallow lakes are presented. Based on investigations of interrelations between variables of freshwater quality by advanced time series analysis methods a process model for phosphorus remobilisation from lake sediments was developed. For predicting the changing water quality of shallow riverine lakes caused by internal pol...

From the abstraction point and the entrance of water in a Water System (WS) till its discharge back to the environment, water passes through a number of treatments and uses that directly affect its quality. The water quality changes several times while the water returning to the environment at a discharge point into the sea, a lake or a river has poorer quality compared to the water entering th...

The paper discusses the problems associated with environmental modelling and the need to consider uncertainty in the formulation, identification, estimation and validation of environmental models. It introduces the concept of Data-Based Mechanistic (DBM) modelling and contrasts its inductive approach with the hypotheticodeductive approaches that dominate most environmental modelling research at...

This paper presents aspects of a research investigation into nutrient fluxes into and out of an important Irish estuary, Wexford Harbour, located in the southeast of Ireland. Details of the methodology applied, the data collection and analysis and the models used are outlined. In particular, the paper addresses modelling of chlorophyll_a production in the brackish waterbody and its dependency o...
