Application of a Generalized Risk Dynamic Model to a Spillway Design Flood
Risk analysis can provide a logical basis for selecting the optimal design capacity of a flow conveyance hydraulic structure for the least total cost or specified non-exceeding risk levels....
Gropps Lake Dam
Gropps Lake Dam has a concrete ogee spillway with earthen abutments at either end of the spillway. The dam features an internal drainage system, outlet works, an energy dissipator, a steel...
Oxygen Transfer at Spillways
A relationship for oxygen transfer efficiency, E, at spillways and gated spillways with a hydraulic jump or plunge pool, has been developed from conceptual considerations and fit to measurements...

Performance of Pipe Spillways for Dams
The Soil Conservation Service has used several different kinds of pipe products for spillway conduits of dams. Materials with a shorter estimated life are used for smaller low hazard dams...
Whitfield Reservoir Inlet Outlet Pipeline
Alameda County Water District reports on the planning, design and construction of a 48-inch water main installed under modern urban circumstances. The location of the pipe and the construction...
Restoration of a Buttress Dam
Inspections of Morris Shepard Dam on the Brazos River in Texas revealed serious defects in the dam and its foundation. Piezometric pressures below the spillway buttresses greatly exceeded...
The Dallas Floodway?Past and Present Successes in Flood Protection Benefits
This paper explores the history of the Dallas Floodway, past performance of the project under various flood conditions and, most recently, the present successes in flood protection provided...
Water Measurement and Accounting of Lake Michigan Diversion
The diversion of water from Lake Michigan and the Lake Michigan Basin into the Mississippi River Basin has been regulated since the turn of the century. The U.S. Supreme Court Decree of...
Inclusion of Wetlands in Designated Floodway Studies
The purpose of this paper is to propose a change in the traditional methods and procedures used by hydrologist and hydraulic engineers to define floodways and floodway fringe areas. We...
Sacramento-San Joaquin Delta The Key to Water Transfer
The Delta is a key feature in California's water resources picture. This ecologically sensitive area is currently experiencing adverse effects from water diversions and needed...
Owens Valley Groundwater Basin Proposed Management
The City of Los Angeles imports over 60 percent of its water supply from the Owens River Watershed through a program of groundwater pumping and surface water diversions as a part of the...
Risk Analysis as a Tool to Determine Spillway Design Capacities
Lyman Dam is an earth and rockfill structure located on the Little Colorado River approximately 11 miles south and upstream of St. Johns, Arizona. Several studies examining the safety...
Innovative Spillway Design
The Lake Alan Henry Dam, near Lubbock, Texas, will consist of an earth filled embankment, a service spillway and an emergency spillway. The service spillway is designed to handle flows...
Scale Effects of Overflow-Oriented Hydraulic Parameters for a High Dam
This paper presents the findings of prototype observation and model verification on the surface velocity, the range of nappe jetting, and the diffusion regime of the discharged flow related...
Comparison of Flush and Chamber Mounted Dynamic Pressure Transducer
Modeling of hydraulic structures often includes the measurement of dynamic pressure fluctuations. The accuracy of the pressure measurements depends upon the geometry of the tap. Flush...
Effects of Spillway Operation on Cavitation Damage to Hugh Keenleyside Dam Spillway
The Hugh Keenleyside Dam (also known as Arrow Dam) is located on the Columbia River, at the outlet of Lower Arrow Lake, 53 km north of the Canada - U.S.A. border. The project has been...
Minimizing Erosion Damage to Embankments, Spillways, and Channels With Articulated Concrete Block Revetment Systems
The results of a multi-year applied research and testing program, focusing on the hydraulic performance of various types of erosion control products and revetment systems in steep-slope...
