Incipient Resuspension of Silt-Clay Sediment
The laboratory study of incipient motion of fine-grained cohesive sediment under oscillatory flow, unidirectional flow and the combined effects of oscillatory and unidirectional flow is...
Scour and Fill Monitoring at Lock and Dam No. 26 (Replacement), Mississippi River
Information gathered during construction of the first stage dam is presented. The information consists of data indicating flows and stages along with data obtained from surveys which monitor...
Numerical Simulation of the Bed Armoring Process
The stability of a river channel depends to a great extent on sediment characteristics. If the amount of sediment coming into a given reach for some reason becomes less than the river's...
Water and Sediment Movement in Irrigation Furrows
Water movement in an irrigation furrow is simulated by numerically solving the governing equations of continuity and momentum for unsteady, spacially varied flow in a pervious bed open...
Modeling of a Multifunctional Hydraulic Structure
A 1:12 scale Froude model of a hydraulic control structure in the Rochester Combined Sewer Overflow Abatement Program (RCSOAP) was constructed and tested to optimize the design requirements...
LTER and Management of the Upper Mississippi River
The Upper Mississippi River is managed for multiple use by two federal agencies and five states. System management objectives include commercial navigation, commercial fisheries, minimum...
Nebraska's Shrinking Platte River Channel: Hydrologic Aspects and Implications
Biologists have proposed two hypotheses to explain recent channel narrowing and vegetative growth in flood plain habitat areas along the Platte River in Nebraska. One group contends, without...
Alternative Layouts for Hydro Headrace Tunnels
The recent development of tunnel boring machines capable of excavating hard rock at virtually any grade together with the Norwegian experience in compressed air surge tanks provides the...
Power from a Water Supply System: A Resource Which Can Be Tapped
There are numerous water supply systems from which hydroelectric power could be developed without impending the regular operational schedule. The basic principle of operation is not different...
Incorporating a Hydro Plant into a Municipal Water System
While recently reformulating water use strategy and policy in association with the development of a new water supply reservoir, a large North Carolina municipality was prompted to assess...
Camp Far West Hydroelectric Project--From Concept to Reality
The project has progressed through a series of predictable development stages including a detailed feasibility study, major project licensing, an environmental Initial Study and Negative...
Hannibal Hydroelectric Project Ecological Concerns
In January, 1983 the City of New Martinsville, West Virginia filed a license application with the Federal Energy Regulatory Commission (FERC) to construct and operate a 34 MW hydroelectric...
Development of Toxic Screening Models for Surface Water Supplies
A major interest of the U. S. Environmental Protection Agency has been the assessment or ranking of vulnerable water utilities. Until recently, no techniques have been available that quantitatively...
Research in Hydraulics at California Institute of Technology
Activities are centered in the W. M. Keck Laboratory of Hydraulics and Water Resources. Research projects active at the Laboratory reflect a continuing commitment to traditional areas...
Lifeline Earthquake Engineering
Performance, Design and Construction
Lifeline Earthquake Engineering: Performance, Design and Construction is a follow-up publication to the Technical Council on Lifeline Earthquake Engineering publication Advisory Notes...
Computer Links Facilities Management, Mapping
Computerizing of map drafting alone was not cost effective, so electric and gas utilities are using their systems to aid in managing their facilities. This article is a case history of...
Software Development: For Experts Only?
Civil engineering firms tend to buy ready-made software rather than develop it themselves. But if existing software for specific applications is unavailable or of poor quality, then the...
Managing by Database
Many computer programs are available for managing the operations and maintenance aspects of a facility. To date, most computer programs for managing a facility have been generated by mechanical...
Light Rail Gains New Momentum
Light rail, which evolved from the old trolley lines, is staging a comeback in U.S. cities. Light rail is a fixed guideway, operator controlled system, offering an alternative to heavy...
Building on Air
Copley Place, a $500 million hotel/retail/office/residential complex, was built on air rights over the Massachusetts Turnpike and an adjacent railroad in Boston. Two hotels occupy land...
