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.

Die dritte Auflage des Klassikers Stahlbetonbrücken behandelt in umfassender Form die Grundlagen des konzeptionellen Entwurfs sowie der Projektierung, Ausführung und Erhaltung von Brücken aus Stahl- und Spannbeton. Diese Grundlagen sind entscheidend für die Ästhetik, Tragsicherheit, Dauerhaftigkeit und Wirtschaftlichkeit einer Brücke. Mit einfachen Modellen wird ein Höchstmaß an Klarheit und Verständlichkeit erreicht. Auf Detailberechnungen wird verzichtet, da sie meist von sekundärer Bedeutung sind und weder auf die Qualität noch auf die Wirtschaftlichkeit einer Brücke einen nennenswerten Einfluss haben. Für Qualität und Dauerhaftigkeit von Stahlbetonkonstruktionen spielen die Anordnung der Bewehrung und die konstruktive Ausbildung eine entscheidende Rolle, weshalb grundsätzliche Lösungsmöglichkeiten dargestellt werden. Die Themen Entwurf, Baustoffe, Einwirkungen, Ausrüstungsteile, Schrägkabelbrücken und Erhaltung wurden grundlegend überarbeitet und erweitert.

In this century, the United States will be challenged to provide sufficient quantities of high-quality water to its growing population. Water is a limiting resource for human well-being and social development, and projections of population growth as well as changing social values suggest that demands for this resource will increase significantly. These projections have fueled concerns among the public and water resources professionals alike about the adequacy of future water supplies, the sustainability and restoration of aquatic ecosystems, and the viability of our current water resource research programs and our institutional and physical water resource infrastructures. With the goal of outlining a roadmap to guide policymakers, the Water Science and Technology Board (WSTB) held a series of discussions at several of its meetings in 1998-2000 about the future of the nation's water resources and the appropriate research needed to achieve their long-term sustainability. From those discussions, the board produced this report, the objectives of which are to: draw attention to the urgency and complexity of water resources issues facing the United States in the twenty-first century; broadly inform decision makers, researchers, and the public about these issues and challenges; identify needed knowledge and corresponding water resources research areas that should be emphasized immediately and over the long term; and describe ways in which the setting of the water research agenda, the conduct of water research, and investments devoted to such research should be improved in the next few decades. This report discusses major research questions related to the critical water issues that face the nation. It lays out an interdisciplinary research portfolio for the next 20 years and recommends agenda-setting processes that can maximize the nation's ability to prioritize and conduct water resources research.
