Proceedings of the 2014 Rocky Mountain Geo-Conference held in Lakewood, Colorado, on November 7, 2014. Sponsored by the Geo-Institute Chapter of the Colorado Section of ASCE, the Rocky Mountain Section of the Association of Environmental and Engineering Geologists, and the Colorado Association of Geotechnical Engineers. Geotechnical Practice Publication No. 9 contains 11 papers that address the complex geotechnical challenges in geologic hazards, nondestructive evaluation, geo-construction, and the ground itself. Topics include: seepage reduction on dams and levees; debris flow risk assessment; testing rockfall barrier systems; landslide hazard ranking and remediation; collapsing soils; ground classification system for excavations; and flooding impacts on Left Hand Creek. GPP 9 focuses on Colorado and the Rocky Mountain West.s specific geotechnical practice and experience. It will be valuable to anyone in geotechnical engineering, especially those working in similar geologic settings.

Sponsored by the Hydropower Technical Committee of the Energy Division of ASCE; U.S. Department of Homeland Security, Federal Emergency Management Agency; Interagency Committee on Dam Safety; U.S. Army Corps of Engineers, Engineer Research and Development Center. Water Control Gates: Guidelines for Inspection and Evaluation provides information and techniques for assessing water control gates, focusing particularly on those controlling reservoirs impounded by a dam. As many dams in the United States reach or pass their 50-year design lives, water control gates and other features must be examined to determine their condition for continued reliable, safe use. This single volume covers the most common types of major water control gates used throughout the last century in the United States. Topics include: description of various water control gates and operating systems; gate operation; gate maintenance; preparing for a gate inspection; conducting visual gate and gate operating system inspections; gate system testing; and the evaluation process. Appendixes provide inspection checklists; example procedures for inspection and testing; guidelines for crane inspection; calculations for determining curvilinear water pressure on a gate face; and potential failure mode examples. The volume includes references and an extensive bibliography. This volume will help owners of dams, whether large or small, to develop a comprehensive plan to actively manage their dam gates. Hydraulic engineers, water resources managers, and emergency planning officials also will rely on this compilation as a reference for managing and maintaining water control gates.

Today, the designer of a hydroelectric facility has to take a variety of issues into consideration including the protection of and mitigation for fish and wildlife, the protection of recreational opportunities, and the general preservation of environmental quality. This results in the need for accurate, continuously-regulated bypass flows, fish entrainment prevention, and other environmental mitigation. These can reduce the amount of head and flows available for power generation. Therefore, power plants have to operate at maximum efficiency to make the most of the available head and flows in order to be economically viable. Under the Energy Division of the American Society of Civil Engineers, a multi-discipline task committee was formed to develop a state-of-the-art guidelines document for the sound environmental design of hydropower intakes. This document, ASCE Guidelines Design of Intakes for Hydroelectric Plants, includes over 400 pages, many of which are graphics and photos, that provide information on intake types and features, hydraulic design considerations, forebay, trashrack and gate design, structural design, fisheries considerations, ice, sedimentation, environmental factors, hydraulic models, and evaluation of existing intakes. These guidelines factor in years of experience of specialists from the engineering and biological communities and is intended for use by new planners and designers of intake structures for hydroelectric plants as well as provide specialized information on a variety of topics related to intake design.

Papers from a conference, Against the Deluge: Storm Surge Barriers to Protect New York City, held in Brooklyn, New York, March 30-31, 2009. Conference sponsored by the Infrastructure Group of the Metropolitan Section of ASCE; Environmental Sciences Section of the New York Academy of Sciences; Department of Civil Engineering, Polytechnic Institute of New York University. Publication sponsored by the Coasts, Oceans, Ports, and Rivers Institute of ASCE. This report contains 16 papers exploring the development of storm surge barriers to protect New York City and nearby New Jersey from the effects of a future deluge. Although the main focus is mitigating the effects of a hurricane, rising sea levels may require protection for the city from what are now minor surges. These papers form a foundation for the scientific and engineering research necessary to evaluate the barrier concept and explore options for its design and execution. Topics include: modeling, simulation, and estimated effects of wind and storm surges; hydrologic feasibility; regulatory issues; ecological and climate issues; geotechnical issues; navigability; and design concepts for barriers at the East River, Verrazano Narrows, Arthur Kill, and Outer Harbor Gateway. This collection is must-reading for coastal engineers, navigation engineers, emergency planners, and government officials in the New York City area, as well as other vulnerable coastal areas.
