This study assembles information related to the applicability of mechanical reliability concepts to the evaluation of water distribution systems. Included in the report is a detailed review of water resources and reliability literature and development of a conceptual basis for a technique or methodology to apply reliability concepts to the design and evaluation of water distribution systems. A comprehensive review of the reliability literature indicates that even the term 'reliability' is ill defined when applied to the analysis of water distribution systems. The concept of availability proved to be a more valuable concept. Methods for quantifying availability of discrete water distribution system components are developed. Specific examples of pump station and pipe reliability analysis are presented. An extensive list of applicable references is included as Appendix A. Of primary interest to the designer of water distribution systems is the inventory of computer codes available for reliability analysis. (Author).

On up-to-date methodologies for the reliability analysis and reliability-based design of water distribution systems. Brings together many new methodologies that can prove valuable in the assessment of aging water distribution systems and in the design and expansion of water supply systems. No index. Acidic paper.

This book contains the lectures given in the International Course "Improving efficiency and reliability in water supply systems", hosted and sponsored by the Menendez Pelayo International University (U.I.M.P.) and co-sponsored by Aguas de Valencia, the British Council and the EC Cornett and Erasmus programmes. The short course took place in Valencia (Spain) in November 1994, with an attendance of more than one hundred delegates. We must not only acknowedge and thank Dr. Joaquin Azagra, as UIMP Director, but also his collaborators D. Luis Moreno and Lidia Lopez for their support in the preparation of the Course and during the course taking place. UIMP sponsorship allowed us to assemble in Valencia an eminent cadre of lecturers coming from all over the world, that covered in an ordered and precise fashion some of the more relevant aspects on efficiency and reliability in water supply systems. We are very thankful to all these leading lecturers for their invaluable cooperation. The publication of this book and the Spanish edition as well, have been made possible thanks to the sponsorship of both Polytechnic University of Valencia througout its Chancellor, Justo Nieto, and Aguas de Valencia throughout its General Director Alvaro Aguirre. We must also thank Kluwer Academic Publishers and especially their Publisher Petra van Steenbergen for her assistance, careful presentation and production of the book.

Computers are widely used for the analysis, design, and operation of water resource projects. This gives accurate results, allowing the analysis of complex systems which may not have been possible otherwise, and the investigation and comparison of several different alternatives in a short time, thereby reducing the project costs, optimizing design, and efficient utilization of resources. This volume compiles an edited version of the lecture notes specially prepared by 14 well-known European and North American researchers. Part I deals with free-surface flows. Governing equations are derived and their solution by the finite-difference, finite-element, and boundary-integral methods are discussed. Then, turbulence models, three-dimensional models, dam-break flow models, sediment transport models, and flood routing models are presented. Part II is related to the modeling of steady and transient pressurized flows. Governing equations for both single and two-component flows are derived and numerical methods for their solution are presented. The modeling of water quality in pipe networks, of cooling water systems, and slow and rapid transients is then discussed.
