Hydraulic Design and Performance of Discharge Facilities at Revelstoke Project
Revelstoke Project is located in southeastern British Columbia on the Columbia River, 130 km downstream of the Mica Dam and approximately 5 km north of the City of Revelstoke. The project...
Roller Compacted Concrete Dams?An Overview
The development of roller compacted concrete for gravity dams is traced from forerunners, through its use at the Shihmen and Tarbela Dam Projects to Willow Creek Dam and the Japanese Roller...
Cedar Falls Roller Compacted Concrete Dam
This paper presents the design, material testing, quality control, and construction considerations applicable to a small Roller Compacted Concrete (RCC) dam. The Cedar Falls RCC dam is...
Comparison of Joint Shear Strengths for Conventional and Roller Compacted Concrete
Direct shear test data for parent material and bonded and unbonded jointed specimens of conventional and RCC (roller compacted concrete) are presented and compared. Results are discussed...
Roller Compacted Concrete Mix Design for Pamo Dam
Pamo Dam is designed as a 265 foot (81M) high gravity dam that will be located on the Santa Isabel Creek in San Diego County, California. RCC volume will be approximately 491,000 cubic...
Evaluation of Cores From Two RCC Gravity Dams
Galesville Dam, Oregon, completed in August 1985, and Upper Stillwater Dam, Utah, completed in August 1987, are two RCC (roller compacted concrete) gravity dams featuring different approaches...
Construction of Elk Creek Dam
Construction of Elk Creek Dam, located in Southwest Oregon, is currently underway with completion scheduled for September 1988. The main dam contract was awarded to Ohbayashi Gumi Ltd....
Whither Roller Compacted Concrete for Dam Construction?
During the formative years of the roller compacted concrete (RCC) dam, three different approaches to the design have evolved; the lean RCC dam, the RCD (rolled-concrete dam) method and...
Roller Compacted Concrete Design for Urugua-I Dam
Gravity dam construction by the roller compacted concrete method (RCC) has received widespread interest following completion of Shimajigawa Dam in Japan (1981) and Willow Creek Dam in...
Sanitary Sewer Model with Database Management
While numerous water supply and stormwater system models existed, the few sanitary sewer models that were readily available were too simplistic for engineering design and master planning...
Sanitary Sewer System Modeling for Operation and Planning
Development of a Steady State Sanitary Sewer Simulation (S5) computer model helped Newport News, Virginia, enact an efficient sanitary sewer management...
Computer-Aided Wastewater Master Planning
Computerized wastewater collection system modeling is a tool now used by city planners and engineers to efficiently and accurately analyze present and future conditions. Once a model has...
Sewer Rehabilitation?Metro Chicago
After a number of public hearings in the late 1960's and early 1970's which focused on sewer backup problems in the Sanitary District's separate...
Rehabilitation Strategies for Urban Drainage Systems?A European Perspective
Rehabilitation of urban drainage system is needed in many old European cities. This is in part due to the required structural upgrading of the existing sewerage system. But rehabilitation...
Underground Storage in Urban Stormwater Management
The use of underground pipe detention basins is discussed. These basins mitigate the frequency of localized flooding and sewer surcharging by effectively increasing the flow capacity of...
Small Diameter Gravity and Pressure Sewers
In communities with low population density or physical features that make conventional gravity sewers inordinately expensive, alternative sewer technologies can be significantly lower...
Lessons to be Learned from Lafayette Tennessee's Small Diameter Sewer System
Lafayette, Tennessee's septic tank effluent, small diameter gravity sewer (SDGS) system is believed to have been the first such project to be funded by the United States Environmental...
Vacuum Sewers: Fundamentals and Design Methods
Vacuum sewer (VS) systems have important advantages over conventional gravity sanitary sewers or septic tank-soil absorption systems when one or more of the following conditions hold:...
Vacuum Sewers: Construction and Operating Experience
As an alternative to conventional collection, the vacuum system has many advantages. Smaller diameter pipes, shallower trenches and the ability to make vertical and horizontal field changes...
Priority Integrated Pipe Evaluation
The selection of the most suitable pipe for a given site involves the consideration of many factors affecting pipe performance. The factors to consider in sewer pipe evaluation and selection...
