Book Description
This book offers a practical guidance for environmental engineers and scientists charged with assessing the cause-and-effect of pollutants in receiving water systems. Instead of blindly running models, which is a practice seen too often in today’s field that can result in results with uncertainty, modelers must first understand the physical insights of the specific water systems in order to properly calibrate the parameters of the models. This book reinforces the critical importance of properly understanding the physical attributes of water systems by drawing on the author’s extensive experience in modeling with strong data support. This is also what sets this book apart from the volumes currently available in the water quality modeling field – nearly all other books in the field are categorized as textbooks, and unlike this book, offer few practical examples or exercises to follow. Environmental engineers and scientists engaged in quantifying the water quality impacts of pollutants to specific water systems will find this book valuable in their day-to-day practices. This book is a necessary volume for water quality engineers and scientists to consult for the regulatory planning and management of water systems

Book Description
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 in detail in the 21 chapters of the book, which is written in a didactic form for professionals and students.

Book Description
This book teaches the fundamentals and principles which underlie the mathematical modeling techniques used to analyze the quality of surface waters. The text first provides an overview of the different bodies of water in which water quality problems need to be addressed before examining specific problems that occur across all bodies of water.

Book Description
Water is an important element for life on the earth. It is an essential natural resource for environmental sustenance. In India, water quality modeling studies are carried out from fresh water to marine water ecosystems. Some of the examples are Tehri reservoir, Chilka lake, Oatcake at Kashmir, Kodaikanal lake, Ooty lake at Tamil Nadu, rivers like Ganges, Narmada, Kaveri, and coastal regions like Hoogly estuary, Paradip, Vishakhapatnam, Kakinada, Chennai, Mangalore coast, Konkan coast and Gujarat coast. Water quality modeling plays a vital role in water quality studies. Numerical models are to be successfully calibrated and properly applied and it is to be improved our understanding of the complex interactions among different parameters such as temperature, biological oxygen demand, dissolved oxygen, salinity, and eutrophication in the fresh water and sea water environment.

Book Description
A Riverine Water Quality Modeling Workshop was held at the U.S. Army Engineer Waterways Experiment Station (WES) on 9-10 April 1980 to address three objectives: (1) define environmental/water quality problems in large rivers encountered by Corps of Engineers (CE) Offices; (2) determine if state-of-the-art riverine models are able to address these problems; and (3) identify areas of inadequacy in the state-of-the-art models for future study and development in the Environmental and Water Quality Operational Studies (EWQOS) Program. To address these objectives, representatives from CE District and Division Offices, other Federal agencies, and the consulting community were invited to participate in the Workshop. At the Workshop, problems were identified in two main areas: water quality problems and problems associated with water quality models. Major water quality problems dealt with reservoir releases and sedimentation. The modeling-related problems included the entire spectrum from new model development to model application problems (i.e. coefficient selection). Workshop recommendations included collecting data sets for a one-dimensional unsteady flow water quality model and for a two-dimensional vertically averaged model. The development and verification of a mathematical algorithm for the transport of fine suspended sediment were also recommended. (Author).
