Opportunities In Dam Planning And Management

Aimed both at practitioners involved in developing country planning processes and dam project managers, this handbook makes a significant contribution to the conversation on modernizing communication in large water infrastructure. --Book Jacket.

This Handbook offers 'how to' ideas to help infrastructure practitioners identify good practice improvements in communication, starting with the World Bank?s own expanding portfolio of dam projects.

Supported by many International agencies.

The concept of a river basin as a management or planning unit has gone through several stages and is in a state of flux.

Residents of areas that could be affected by a dam failure or operational incident have a risk of loss of life, injuries, and damage to property from a failure or operational incident. The purpose of this document is to provide guidelines for the preparation of an Emergency Action Plan (EAP) to facilitate the development of plans that are comprehensive and consistent. The purpose of an EAP is to protect lives and reduce property damage. The intended readers of this document are dam owners and emergency management authorities who work together in the response to dam safety emergencies. An EAP is a formal document that identifies potential emergency conditions at a dam and specifies actions to be followed to minimize loss of life and property damage. The EAP includes: Actions the dam owner will take to moderate or alleviate a problem at the dam Actions the dam owner will take, and in coordination with emergency management authorities, to respond to incidents or emergencies related to the dam

CHECK DAM CONSTRUCTION FOR SUSTAINABLE WATERSHED MANAGEMENT AND PLANNING Authoritative and comprehensive reference on the potential for watershed development through the use of check dams Check Dam Construction for Sustainable Watershed Management and Planning summarizes current knowledge of check dams as key soil and water conservation structures in some of the most sensitive and vulnerable ecosystems in the world, as exemplified by the Mediterranean area and the Chinese Loess Plateau, providing detailed information on check dam design and watershed planning, the use of advanced modeling techniques, challenges in dam construction and how to overcome them. The work integrates decades of research in the field of soil and water conservation and gully management, including advanced studies in check dam construction and watershed management. It also covers important new techniques and methods, such as hydrological modeling, isotope tracing, and more. To aid in reader comprehension, the five highly qualified editors have divided the work into three distinct sections. Sections I and II focus on the experience gained from the erosion hotspots in the Chinese Loess Plateau, whereas Section III expands the scope to other regions with different functions for check dams, including headwater ecosystems and alpine environments. Sample topics covered in Check Dam Construction for Sustainable Watershed Management and Planning include: The regulating effect of check dam systems on sediment redistribution and the formation and development of dam systems in small watersheds Water and soil conservation made possible by check dam construction and sediment source analysis of water-sediment retarding effects of check dams The regulation of check dam systems on the erosion dynamic process and the mechanism of erosion reduction by check dams Flood control risk assessment on warping dam systems and the development and utilization model of check dam systems With its systematic coverage of all aspects of dam construction and maintenance, Check Dam Construction for Sustainable Watershed Management and Planning supports decision making by local authorities and can also be used as a professional guide for ecologists, hydrologists, and water resource managers.

Dam Safety Management is a major concern during the entire lifetime cycle of a dam scheme. This is particularly true for the operational phase of the scheme that represents by far the longest period in its lifetime cycle. Bulletin 154 presented a general approach and concepts to be applied to dam operation. The current Bulletin 175 extends the developed concepts to all phases preceding the operational phase. Many risks associated with the operation of existing dams have their origins in other phases preceding the actual operation. Although there are numerous ICOLD Bulletins addressing technical aspects of planning, design, construction and commissioning of dams, there is not a single Bulletin which covers the subject in a comprehensive manner. The current document is a first attempt to capture all relevant dam safety aspects in all preoperational phases by systematically characterizing the actors involved, their roles, the activities and complex interactions present in different phases of the dam lifecycle. An Overarching Safety Management System is specifically developed that can be applied to all actors involved. La gestion de la sécurité des barrages est une préoccupation majeure pendant tout le cycle de vie d'un projet de barrage. Cela est particulièrement vrai pour la phase opérationnelle du système qui représente de loin la période la plus longue de son cycle de vie. Le Bulletin 154 présente une approche générale et des concepts à appliquer à l'exploitation des barrages. Le Bulletin 175 actuel étend les concepts développés à toutes les phases précédant la phase d'exploitation. De nombreux risques associés à l'exploitation des barrages existants ont leur origine dans d'autres phases précédant l'exploitation proprement dite. Bien qu'il existe de nombreux bulletins ICOLD traitant des aspects techniques de la planification, de la conception, de la construction et de la mise en service des barrages, il n'existe pas un seul bulletin qui couvre le sujet de manière exhaustive. Le document actuel est une première tentative de capturer tous les aspects pertinents de la sécurité des barrages dans toutes les phases pré-opérationnelles en caractérisant systématiquement les acteurs impliqués, leurs rôles, les activités et les interactions complexes présentes dans les différentes phases du cycle de vie du barrage. Un système global de gestion de la sécurité est spécifiquement développé et peut être appliqué à tous les acteurs impliqués.

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.
