Описание: Discusses two of the main concerns in respect of water supply systems are their efficiency and their reliability. This book features five sections: Fundamentals; Leakage Detection in Networks; Network Management: Leakage Control; Managing Water Distribution Systems to Reduce Energy Costs; and, Reliability, Risk Analysis and Rehabilitation.
Описание: This book uses advanced sophisticated modeling tools to decribe optimal water management in a complex distribution system using retention reservoirs, among which water transfers are possible, and a network connecting reservoirs and water treatment plants.
Описание: 35 leading multi-disciplinary scientists with international reputations provide reviews of topical areas of research on uncertainty and reliability related aspects of water resource systems. The volume will be valuable for graduate students, scientists, consultants, administrators, and practising hydrologists and water managers.
Описание: Rural Water Systems for Multiple Uses and Livelihood Security covers the technological, institutional, and policy choices for building rural water supply systems that are sustainable from physical, economic, and ecological points-of-view in developing countries. While there is abundant theoretical discourse on designing village water supply schemes as multiple use systems, there is too little understanding of the type of water needs in rural households, how they vary across socio-economic and climatic settings, the extent to which these needs are met by the existing single use water supply schemes, and what mechanisms exist to take care of unmet demands. . The case studies presented in the book from different agro ecological regions quantify these benefits under different agro ecological settings, also examining the economic and environmental trade-offs in maximizing benefits. This book demonstrates how various physical and socio-economic processes alter the hydrology of tanks in rural settings, thereby affecting their performance, also including quantitative criteria that can be used to select tanks suitable for rehabilitation.

Описание: At the same time there is a demand for more effective approaches to the design of procedures for the operation and use of man- made systems, more meaningful assessment of the risks introduced, and use such a system poses both when operating as designed and when operating at below design performance.
