Hydraulics of Broad Crested Weirs
The paper presents a general, basic discussion of the title subject. It begins with a definition for the broad crested weir and analytical concepts. Subjects covered subsequently include...
Velocity Distribution Factor Constraints
It has been customary to introduce the velocity distribution factors alpha and beta into the energy and momentum equations so as to avoid the integration associated with variations in...
Guideway and Conductor Rail Heating for a Winter Environment
The power and signal conducting rails are maintained using self-limiting heat trace cable in combination with an inherently protected rail. The cable's high inrush power along...
Particles, Pretreatment, and Performance in Water Filtration
Relationships among raw water quality, pretreatment facilities, and the design of packed bed filters are presented and applied. The particle size, particle concentration, particle surface...
Effects of Streambed Processes on Interaction Between Surface and Groundwater
In open channel systems, the phenomena commonly referred to as 'clogging' is caused by settling of sediment and straining of suspended material as water moves...
Strength of Soils in Terms of Effective Stress
The factors that determine soil strength, such as amount of confinement, density, particle size distribution, mineral friction, aging, particle crushing, and others, produce their effects...
Thermal Design Considerations in Frozen Ground Engineering
Prepared by the Technical Council on Cold Regions Engineering of ASCE. The design of engineering projects in frozen ground requires thermal design considerations...
Advances in Short Span Steel Bridges
Applying recent research to the design of short span steel bridges can lower their cost and maintenance. Such research involves improved limit state criteria, more uniform lateral load...
An Extreme-Value Model for Strength of Stiff Clays
The role of the distribution function in the safety analysis of soil structures is briefly discussed. Comparison of the two statistical distributions - normal and Weibull - reveals that...
A Pseudo Response Spectrum Method for Mark I Loads
A pseudo base motion response spectrum method is developed to uniquely evaluate the periodic condensation oscillation and chugging drag loads that may occur on submerged structures within...
Stress Distribution Around the Equipment Hatch Opening of a Prestressed Concrete Containment for a PWR Power Station
Results are reported of a finite element stress analysis for the linear elastic deformation around the equipment hatch opening in prestressed concrete containment. The dimensions and form...
Capability of LMFBR Plant Structures Beyond the Design Base
A study is presented concerning the capability of structures in a loop type Liquid Metal Fast Breeder Reactor Plant, the Clinch River Breeder Reactor Plant (CRBRP), to sustain conditions...
Waste Phosphatic Clay Disposal in Mine Cutsr
Research was undertaken to assess the applicability of waste clay disposal back into phosphate mine cuts. The pit was monitored for two years with measurements of clay surface elevation,...
Automated Walking Cycle for Swinging Ladder Dredge
The unique application of a Swinging Ladder Dredge to perform maintenance dredging in the cooling canal system of the Turkey Point Power Plant demanded the design of a semi-automated dredge...
Influence of Roughness on Velocity and Dispersion at Low Flow
Dependence of the hydraulic and transport characteristics of low flow on channel roughness is investigated. Empirical expressions are used to estimate roughness coefficient as a function...
Effects of High Sediment Concentrations on Velocity and Sediment Distributions
Several classifications are required to describe sediment-transporting flow. The flow may be turbulent or laminar, Newtonian or non-Newtonian, and may also have a uniform or nonuniform...
Japanese Experience with Intake Designs
To diversify its power sources, Japan has operating or under construction some 37 nuclear power units. This technology and the design criteria are imported from the U. S. The power plants...
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...
Experimental Study of Stratified Cooling Ponds
Experiments in a laboratory physical model were conducted to analyze the hydrothermal performance of vertically stratified cooling ponds. Temperature, velocity, and fluorescent dye measurements...
Simulation of River Ice Cover Growth and Decay
A model of ice cover thermodynamics was used to simulate ice growth and decay along the international section of the St. Lawrence River for the winter of 1980-81. At the air-ice interface,...
