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

Book Description
Abstract: The use of multimetric biological indices (e.g., IBI, ICI, MIwB) to assess aquatic communities is well established in Ohio. These indices provide a definitive numeric assessment of the stream biotic communities to judge against established biocriteria in state water quality standards. However, these assessment tools cannot be applied to the smallest headwater streams of watersheds. The Ohio EPA recognizes three different types of primary headwater habitat streams (PHWH) that have watershed area 2.56 km2 and deep pools

Book Description
This book examines the application of fish community characteristics to evaluate the sustainability and biological integrity of freshwaters. Topics include perspectives on use of fish communities as environmental indicators in program development, collaboration, and partnership forming; influence of specific taxa on assessment of the IBI; regional applications for areas where the IBI had not previously been developed; and specific applications of the IBI developed for coldwater streams, inland lakes, Great Lakes, reservoirs, and tailwaters.

Book Description
Authored by world-class scientists and scholars, the Handbook of Natural Resources, Second Edition, is an excellent reference for understanding the consequences of changing natural resources to the degradation of ecological integrity and the sustainability of life. Based on the content of the bestselling and CHOICE awarded Encyclopedia of Natural Resources, this new edition demonstrates the major challenges that the society is facing for the sustainability of all wellbeing on planet Earth. The experience, evidence, methods, and models used in studying natural resources are presented in six stand-alone volumes, arranged along the main systems: land, water, and air. It reviews state-of-the-art knowledge, highlights advances made in different areas, and provides guidance for the appropriate use of remote sensing data in the study of natural resources on a global scale. The six volumes in this set cover: Terrestrial Ecosystems and Biodiversity; Landscape and Land Capacity; Wetlands and Habitats; Fresh Water and Watersheds; Coastal and Marine Environments; and finally Atmosphere and Climate. Written in an easy-to-reference manner, the Handbook of Natural Resources, Second Edition, as a complete set, is essential for anyone looking for a deeper understanding of the science and management of natural resources. Public and private libraries, educational and research institutions, scientists, scholars, and resource managers will benefit enormously from this set. Individual volumes and chapters can also be used in a wide variety of both graduate and undergraduate courses in environmental science and natural science courses at different levels and disciplines, such as biology, geography, Earth system science, ecology, etc.

Book Description
This book provides the focal point of the European Water Framework Directive. offering insight into principles and methodologies of river assessment, covering the whole range from the definition of river typologies to specific problems such as the most appropriate taxonomic resolution and software applications. The text focuses on benthic macroinvertebrates, the taxonomic group most frequently used in bioassessment.

Book Description
Biological Assessment and Criteria presents a state-of-the-art overview of the applications of biological assessments and biocriteria for water quality management in fresh waters. The book presents case studies which illustrate how bioassessment has been used to identify and diagnose water quality problems. It also provides examples of the use of qualitative and quantitative biocriteria as regulatory tools to complement water quality criteria and standards. The first book to present the technical foundation, rationale, program and policy relevance, and legal basis for the most accurate tools used to assess freshwater natural resource and regulatory efforts, this book provides useful and timely information for water quality managers.

Book Description
We all rely on a familiar set of indicators - interest rates, unemployment, inflation, the Dow Jones index, and GDP, for example - to gauge the performance of national economies. No such measures are currently available to describe the environment. This book lays out a blueprint for periodic reporting on the condition and use of ecosystems in the United States. Developed by experts from businesses, environmental organizations, universities, and federal, state, and local government agencies, it is designed to provide policymakers and the general public with a succinct and comprehensive - yet scientifically sound and non-partisan - view of 'how we are doing'. This book should prove invaluable for decision makers in natural resource management and environmental policy in government and environmental organizations, businesses, and trade associations; academics with a research or teaching interest in environmental issues; and the general public interested in the continued well-being of American ecosystems.
