Water Quality Indices

Water Quality Indices PDF Author: Tasneem Abbasi
Publisher: Elsevier
ISBN: 044454304X
Category : Science
Languages : en
Pages : 362
Book Description
This book covers water quality indices (WQI) in depth - it describes what purpose they serve, how they are generated, what are their strengths and weaknesses, and how to make the best use of them. It is a concise and unique guide to WQIs for chemists, chemical/environmental engineers and government officials. Whereas it is easy to express the quantity of water, it is very difficult to express its quality because a large number of variables determine the water quality. WQIs seek to resolve the difficulty by translating a set of a large number of variables to a one-digit or a two-digit numeral. They are essential in communicating the status of different water resources in terms of water quality and the impact of various factors on it to policy makers, service personnel, and the lay public. Further they are exceedingly useful in the monitoring and management of water quality. With the importance of water and water quality increasing exponentially, the importance of this topic is also set to increase enormously because only with the use of indices is it possible to assess, express, communicate, and monitor the overall quality of any water source. Provides a concise guide to WQIs: their purpose and generation Compares existing methods and WQIs and outlines strengths and weaknesses Makes recommendations on how the indices should be used and under what circumstances they apply

International River Water Quality

International River Water Quality PDF Author: Gerry Best
Publisher: CRC Press
ISBN: 9780419215400
Category : Science
Languages : en
Pages : 310
Book Description
This book is a collection of papers presented at the 2nd International River Quality Symposium. The papers give case studies of the quality of rivers in different parts of the world, focusing particularly on the polluted Vistula River in Poland and the revived Will amette River in Oregon, USA which was the subject of a major cleaning operation in the 1970s. The book provides valuable information on the quality of rivers in Eastern Europe, particulary Poland. It is timely since, with the collapse of communism, Eastern European countries are faced with tackling huge environmental problems created by the lack of investment in environmental technology. The situation in Poland is contrasted with the USA and UK where water pollution problems have largely been overcome.

Lake Sciences and Climate Change

Lake Sciences and Climate Change PDF Author: Mohamed Nageeb Rashed
Publisher: BoD – Books on Demand
ISBN: 9535125567
Category : Science
Languages : en
Pages : 202
Book Description
Lakes are highly essential for their water quality, habitat suitability, and water supply. Lakes constitute important source for aquatic life, fish, wildlife, and human, but can undergo rapid environmental changes. Most important factors that affect lake ecosystem are climate, atmospheric inputs, land use, morphology, and physiography. Several environmental problems can affect a lake's water quality, and habitat suitability. The book "Lake Sciences and Climate Change" deals with several aspects of lake sciences (botany, zoology, geology, chemistry, models, morphology, and physiography) ,as well as the effect of climatic changes on lake body ecosystem. The book is divided into three sections and structured into 10 chapters. The first section discusses the relationship between lake and climatic change; the second section explains lake biology and health; and the third section focuses on water quality, management, and modeling. Scientists from different fields of lake sciences reported in this book their findings.

Water Quality Management

Water Quality Management PDF Author: Gholamreza Asadollahfardi
Publisher: Springer
ISBN: 3662447258
Category : Science
Languages : en
Pages : 118
Book Description
Considering the significance of water quality for drinking, irrigation and industry, availability of accurate and sufficient water quality data is necessary and having enough data without proper interpretation is not helpful for water quality management decisions. Hence, analysis of the existing data and prediction of future of water quality is vital. The current volume first defines the importance of water quality parameters regarding public health and irrigation. Secondly, the climatic situation and hydrological cycle of the area is considered for interpretation of the data. Various methodologies such as Box-Jenkins time series analysis, water quality indices, artificial neural networks and principal component analysis are described and applied to actual data for different environmental conditions such as arid, semiarid and mountainous areas. This book is a user manual for students and professionals involved in water quality planning and management.
