Data on water quality and other environmental issues are being collected at an ever-increasing rate. In the past, however, the techniques used by scientists to interpret this data have not progressed as quickly. This is a book of modern statistical methods for analysis of practical problems in water quality and water resources.The last fifteen years have seen major advances in the fields of exploratory data analysis (EDA) and robust statistical methods. The 'real-life' characteristics of environmental data tend to drive analysis towards the use of these methods. These advances are presented in a practical and relevant format. Alternate methods are compared, highlighting the strengths and weaknesses of each as applied to environmental data. Techniques for trend analysis and dealing with water below the detection limit are topics covered, which are of great interest to consultants in water-quality and hydrology, scientists in state, provincial and federal water resources, and geological survey agencies.The practising water resources scientist will find the worked examples using actual field data from case studies of environmental problems, of real value. Exercises at the end of each chapter enable the mechanics of the methodological process to be fully understood, with data sets included on diskette for easy use. The result is a book that is both up-to-date and immediately relevant to ongoing work in the environmental and water sciences.

Research on reservoir sedimentation in recent years has been aimed mainly at water resources projects in developing countries. These countries, especially in Africa, often have to cope with long droughts, flash floods and severe erosion problems. Large reservoir capacities are required to capture water provided by flash floods so as to ensure the supply of water in periods of drought. The problem arising however is that these floods, due to their tremendous stream power, carry enormous volumes of sediment which, due to the size of reservoirs, are virtually deposited in toto in the reservoir basin, leading to fast deterioration of a costly investment. Accurate forecasting of reservoir behaviour is therefore of the utmost importance.This book fills a gap in current literature by providing in one volume comprehensive coverage of techniques required to practically investigate the effects sediment deposition in reservoirs has on the viability of water resources projects. Current techniques for practically estimating sediment yield from catchments, estimating the volume of sediment expected to deposit in reservoirs, predicting sediment distribution and calculating scour downstream of reservoirs are evaluated and presented. The liberal use of diagrams and graphs to explain the various techniques enhances understanding and makes practical application simple. A major feature of the book is the application of stream power theory to explain the process of reservoir sedimentation and to develop four new methods for predicting sediment distribution in reservoirs.The book is primarily directed at practising engineers involved in the planning and design of water resources projects and at post-graduate students interested in this field of study.

Written by two of the world’s leading experts on sediment management, 'Extending the Life of Reservoirs' provides guidance on adopting sediment management practices for hydropower and water supply dam projects. It explains how ensuring long-term resilience of critical infrastructure requires early and constant attention to reservoir sedimentation processes, which can reduce the storage capacity of reservoirs and damage hydro mechanical equipment. The report provides concrete guidance on safeguarding against these effects and preserving the many important services of hydropower and dam projects, including water supply, irrigation, and renewable electricity. In particular, it stresses the importance of integrating sediment management into the early planning phases of projects. 'Extending the Life of Reservoirs' is designed to assist those evaluating dam and hydropower proposals. While for the primary audience includes policy makers, lending agencies, and general practitioners, the level of detail provided in the report should appeal to a wide array of stakeholder groups. The content is neither overly technical nor overly simplistic, and aims to provide practical and useful information. Importantly, this report provides a new perspective on the importance of sediment management that is not found in prior work. It stresses the value of sediment management measures as a robust adaptation measure to support sustainable hydropower. The techniques described in the report make sense regardless of future climate changes, but in many cases have even more value when uncertainty over future hydrological patterns is taken into account.
