Without proper hydraulic fill and suitable specialised equipment, many major infrastructure projects such as ports, airports, roads, industrial or housing projects could not be realised. Yet comprehensive information about hydraulic fill is difficult to find. This thoroughly researched book, written by noted experts, takes the reader step-by-step through the complex development of a hydraulic fill project. Up-to-date and in-depth, this manual will enable the client and his consultant to understand and properly plan a reclamation project. It provides adequate guidelines for design and quality control and allows the contractor to work within known and generally accepted guidelines and reasonable specifications. The ultimate goal is to create better-designed, more adequately specified and less costly hydraulic fill projects. The Hydraulic Fill Manual covers a range of topics such as: • The development cycle of a hydraulic fill project • How technical data are acquired and applied • The construction methods applicable to a wide variety of equipment and soil conditions, the capabilities of dredging equipment and the techniques of soil improvement • How to assess the potentials of a borrow pit • Essential environment assessment issues • The design of the hydraulic fill mass, including the boundary conditions for the design, effects of the design on its surroundings, the strength and stiffness of the fill mass, density, sensitivity to liquefaction, design considerations for special fill material such as silts, clays and carbonate sands, problematic subsoils and natural hazards • Quality control and monitoring of the fill mass and its behaviour after construction. This manual is of particular interest to clients, consultants, planning and consenting authorities, environmental advisors, contractors and civil, geotechnical, hydraulic and coastal engineers involved in dredging and land reclamation projects.

The water impounded behind a dam can be used to generate power and to provide water for drinking, irrigation, commerce, industry, and recreation. However, if a dam fails, the water that would be unleashed has the energy and power to cause mass destruction downstream, killing and injuring people and destroying property, agriculture, industry, and local and regional economies. The U.S. Bureau of Reclamation (Reclamation) is responsible for managing and operating some of this nation's largest and most critical dams. The failure of one or more of these dams as the result of a malicious act would come with little warning and a limited time for evacuation. In the years since the 9/11 attacks, Reclamation has invested significant resources to establish and build a security program. Reclamation is now ready to evaluate the results of these efforts and determine how best to move forward to develop a security program that is robust and sustainable. This book assesses Reclamation's security program and determines its level of preparedness to deter, respond to, and recover from malicious acts to its physical infrastructure and to the people who use and manage it.
