Higher-Order Methods for Transient Free-Surface Flows
One-dimensional transient free-surface flows in open channels are described by a set of quasi-linear hyperbolic partial differential equations, called the Saint-Venant equations. Numerical...
Predicting Ground-Water Drainage to Surface Mines
A two-dimensional, finite-difference numerical model is used to simulate the drainage of ground water into a surface coal mine. Graphs of dimensionless head as a function of dimensionless...
Flood Travel Time
The effects of infiltration on the flood travel time are investigated. In flood prediction, the physical domain for flood cumulation is expressed by the period of time for water to travel...
Cavitation Inception from Cylindrical Holes
The inception of cavitation due to circular holes in a boundary is studied. Laboratory experiments were conducted to define limited cavitation as a function of the hole depth to diameter...
Movable-Bed Model Investigation of Littoral Drift on the Intake and Outlet of Lin-Kou Power Plant (I)
The establishment and operation of a distorted movable-bed model of the cooling water intake and outlet is described. The model employed is a three-dimensional movable-bed Froude model...
Prediction of Dam Overtopping Due to Mudflows
The eruption of Mount St. Helens on May 18, 1980 resulted in a small mudflow into Swift reservoir, which is located immediately south of the mountain. An engineering/geologic study was...
Hydraulics and Hydrology of Border Irrigation
Proper description of the hydraulics of irrigation of farmland is necessary in management. Many descriptions of furrow or border irrigation are not adequate to describe truly physically...
Thermal Breakup Predictions on a Regulated River
The thermal breakup process which occurs on the Peace River in Alberta, Canada is described. A quantitative technique which uses the energy budget to explain the celerity of the breakup...
The Importance of Nonlinear Wave Interactions Under Ice
Waves under ice interact at the second order in wave slope. Because of this, a monochromatic wave train impinging on an ice sheet can transfer a significant amount of energy to its own...
Hydraulics of Freeze-up
A classification scheme for freeze-up of a river is proposed based upon the response of indicated stage. A conceptual model is developed to describe the course of the indicated responses....
Recreational Freshwater Embayment Design for Acceptable Water Quality
Combined field and laboratory studies were used to relate water quality, geometry, and exchange characteristics in reservoir swim embayments. Water surface fluctuations in reservoirs are...
Dual Source Water Supply Facilitates Power Plant Start-Up
The make-up cooling water supply for a four unit coal-fired steam turbine generating station required a peak demand of 28,000 gallons per minute (62. 4 cubic feet per second). Following...
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...
Kinematic Shock: A Sensitivity Analysis
A series of numerical experiments is performed to determine the flow and channel characteristics that are most conducive to kinematic wave steepening and associated shock phenomena. A...
Guidelines for the Seismic Design of Oil and Gas Pipeline Systems
Current knowledge on the practice of earthquake engineering for oil and gas pipeline systems is presented. Such systems typically consist of buried oil, gas, or product pipelines and aboveground...
Coastal Engineering Abstracts 1984
Proceedings of the 19th International Conference on Coastal Engineering held in Houston, Texas, September 3-7, 1984. Sponsored by the American Society of Civil Engineers, the Institute...
The Third Wave in Water Quality Management
In the 1970's there was great pressure to clean up water-polluting discharges no matter what the cost. Now in the tight-budget 1980s, there is a vigorous search for more cost-effective...

Directional Wave Spectra Applications
These collected papers and their ensuing discussions presented at the September, 1981 symposium at the University of California on directional wave spectra applications examine the present...
Bibliography on Ocean Energy
With the prospect of an increasing shortage of energy resources, there has been a growing interest in renewable alternative sources of energy. An increasing effort is being directed towards...
