Taschenbuch. Zustand: Neu. Neuware -The most effective means of consistently ensuring the safety of a drinking water supply is through the use of a comprehensive risk assessment approach that encompasses all steps in water supply from catchment to consumer. The approach of this book is to promote an understanding of the entire water supply system, including the hazards that can compromise drinking water quality, safety and develops effective measures to assess and manage risks arising from those hazards using spatial model. Comparative evaluation of certain physical, chemical and biological characteristics of raw, treated and potable water at distribution network has been ongoing. Applying a GIS model will provide visual impacts for various hazards using WQI, which has formed a series of prediction maps for risk assessment. The objective of this book is to help researchers, professionals, and end-users working in water supply systems with the identification of relevant hazards by providing a catalogue with potential hazards of technical, environmental or human origin for the entire system.Books on Demand GmbH, Überseering 33, 22297 Hamburg 144 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The pollution of water bodies with nutrients create a rich environment that encourages the growth of algae and invasive water plants such as the Water Hyacinth. The Water Hyacinth in its natural habitat does not represent a major problem, but out of its natural habitat, the water plant double its biomass in less than two weeks. The plants mesh form thick floating mats that rapidly cover the surface of the infested water body. This book presents the development of a Water Hyacinth Model. The model is based in a Demographic growth function and considers growth-limiting factors like nutrients, temperature, solar radiation, pH and biomass density. Three control strategies can be assessed: harvesting the plant, use bio control agents and chemical abatements. The model was developed in the Open Process Library of DELWAQ which facilitates the coupling online with the water quality and hydrodynamic model of Sobek. The book demonstrates the high potential of integration of water quality and ecosystem models in helping to understand the complex relationships between management actions and ecosystems responds.Books on Demand GmbH, Überseering 33, 22297 Hamburg 140 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware - Published in 1992, this book concentrates on recent developments, applications and aspects relating to numerical hydraulic models for predicting flow and water quality parameters in coastal, estuarine and river waters and river systems. The various chapters cover a range of different types of models and discuss the role of such numerical models for environmental impact assessment studies. The book is based on papers presented by leading experts in the field at a symposium held on 13 November 1991, organized by the Tyne and Humber Branch of the Institution of Water and Environmental Management. It covers the latest developments in modelling techniques and approaches and also the concepts of water quality modelling as required and seen from the viewpoints of regulatory agencies such as the NRA, consulting engineers and specialist modelling laboratories such as HR Wallingford and WRc. As well as an up-to-date review, it provides an understanding of the problems relating to water quality modelling, and the scope and requirements for using water quality models in the water industry. Readership includes practising engineers and scientists in the water industry, including consulting engineers, water companies and the NRA and other government departments, university and polytechnic libraries, staff and students and all other members of the water engineering profession._.

Taschenbuch. Zustand: Neu. Neuware -HYPE (Hydrological Predictions for the Environment) model was applied for simulation of discharge and streamwater inorganic nitrogen (IN) concentration in two different meso scale catchments of the German lower mountain range, the Selke (463 km2) and Weida catchments (99 km2). DREAM(ZS) (DiffeRential Evolution Adaptive Metropolis algorithm) was combined with the HYPE model to implement parameter calibration and uncertainty analysis. Results showed that IN concentration and daily IN load had a proportional relationship with discharge, indicating that IN leaching is mainly controlled by runoff. The HYPE model was proved to be capable of capturing dynamics and balances of water and IN load with a Nash-Sutcliffe coefficient above 0.83. Multi-site calibration improved model performances at internal sites and decreased parameter posterior uncertainty ranges as well as prediction uncertainty. Compared with calibration using bi-weekly measurements, nitrogen-process parameters calibrated using daily averages of nitrate-N concentration observations produced better and more robust IN modelling performance, narrower posterior parameter uncertainty ranges and IN prediction uncertainty.Books on Demand GmbH, Überseering 33, 22297 Hamburg 168 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The overall objective of this research is to understand the spatiotemporal dynamics of water quality parameters in different water bodies of South Florida. Two major approaches (multivariate statistical techniques and remote sensing) were used in this study. Multivariate statistical techniques include cluster analysis (CA), principal component analysis (PCA), factor analysis (FA), discriminant analysis (DA), absolute principal component score-multiple linear regression (APCS-MLR) and PMF receptor modeling techniques were used to assess the water quality and identify and quantify the potential pollution sources affecting the water quality of three major rivers of South Florida. Also, the bio-physical parameters associated with the water quality of the two important water bodies of Lake Okeechobee and Florida Bay were investigated based on remotely sensed data. The principal objective of this part of the study is to monitor and assess the spatial and temporal changes of water quality using the application of integrated remote sensing, GIS data, and statistical techniques.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 280 pp. Englisch.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - The main objective of the Water Framework Directive in the European countries is to achieve a 'good status' of all the water bodies, in the integrated management of river basins. In order to assess the impact of improvement measures, water quality models are necessary. During the previous decades the progress in computer technology and computational methods has supported the development of advanced mathematical models for pollutant transport in rivers and streams. This book is intended to provide the fundamental knowledge needed for a deeper understanding of these models and the development of new ones, which will fulfil future quality requirements in water resources management. This book focuses on the fundamentals of computational techniques required in water quality modelling.Advection, dispersion and concentrated sources or sinks of contaminants lead to the formulation of the fundamental differential equation of pollutant transport. Its integration, according to appropriate initial and boundary conditions and with the knowledge of the velocity field, allows for pollutant behaviour to be assessed in the entire water body. An analytical integration is convenient only in one-dimensional approach with considerable simplification. Integration in the numerical field is useful for taking into account particular aspects of water body and pollutants.To ensure their reliability, the models require accurate calibration and validation, based on proper data, taken from direct measurements. In addition, sensitivity and uncertainty analysis are also of utmost importance. All the above items are discussed indetail in the 21 chapters of the book, which is written in a didactic form for professionals and students.
