The Chesapeake Bay Hydraulic Model: Construction, Operation and Verification
This paper discusses significant aspects of the construction, operation, verification and testing at the Chesapeake Bay Hydraulic Model which was operational from May 1976 to August 1984....

Chaotic Characteristics of Snowmelt Runoff: A Preliminary Study
Chaos, the study of nonlinear dynamic systems, offers a way of observing order in systems previously thought to be random. In this study, we analyze snowmelt runoff from a small watershed...

Waves in a Fluid Mud Layer Flowing Down an Incline
To model the dynamics of fluid mud, lava, or debris with a high concentration of cohesive clay particles, we consider a thin sheet of Bingham plastic fluid flowing down a slope. The Bingham...

Experimental Investigation of Density-Driven Hyperconcentrated Flows
Lock-exchange type of laboratory experiments have been conducted in order to evaluate the dynamical characteristics of density-driven hyperconcentrated fluid mud. Fluid mud, confined in...

Resistance Consisting of Both Viscous Force and Dispersive Force
A set of specially designed experiments have been carried for studying the resistance of a flow consisting of water and both fine and coarse particles. The viscous force caused by fine...

A Computational Analysis of Dynamic Interaction of Dam with Reservoir Water and Sediment
A two-dimensional model of porous media is employed to calculate the reduction of the onset hydrodynamic pressure with the bulk modulus of pore water in reservoir sediment. However, the...

Application of the Generalized Channel Routing Model
Using the linear full dynamic finite difference model the applicability of diffusion and kinematic wave models is investigated. Two dimensionless numbers are suggested for applicable range...

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...

Effect of Barrier Beach Breaching on Harbor Dynamics and Storm Surges
This paper presents a summary of the flood insurance study, commissioned by the Federal Emergency Management Agency, to determine the 100-year flood elevation for Chatham, a seacoast town...

Durability of High-Strength Concrete Containing Fly-Ash and Silica Fume
The durability of high-strength concrete made with local materials were tested with regard to the freezing and thawing resistance of concrete in accordance with ASTM C666 procedure A....

Theoretical Prediction of Temperature Distributions in Airfield Runway Pavements Due to Aircraft Operation
The determination of this transient temperature distribution is important in predicting the thermal effects on pavements due to aircraft operation. In this research, heat exchange at the...

Stratified Flows
This volume contains the edited and refereed proceedings of the Third International Symposium on Stratified Flows, convened on February 3-5, 1987 in Pasadena, California. It consists of...

Probabilistic Prediction of Losses to Lifeline Systems Due to Earthquakes
An efficient and practical method for earthquake loss estimation for lifelines is developed, using the recent advances made in the areas of lifeline earthquake engineering and probabilistic...

Taming Structural Vibrations
Vibration is a common problem in buildings that contain large spaces and long spans, especially gymnasiums and dance studios. Research shows that people respond more adversely to continuous...

Structures Congress Abstracts 1990
Abstract only. The following themes are included: Rehabilitation and future challenges, Bridges, Earthquake engineering, Dynamic loads on structures, Metals and composite construction,...

Limit State Analysis Correlated to a Full Scale Tower Test
A Limit State analysis technique has been developed for evaluating the structural capacity of lattice steel electrical transmission towers. The tower strength is determined by using a...

New Outlines for 500 kV Transmission Towers Using Cold-Formed Shapes: The Experimental Line of the American Electric Power Research Institute
The use of cold-formed steel members, in electrical transmission towers, is actually a feasible, reliable and economical solution. The EPRI experimental line is an example of the newest...

Floor Vibrations ? Tips for Designers
The purpose of this paper is to suggest a number of practical concepts which can be used to improve the performance of floor systems subject to occupant induced motion from either walking,...

Seismic Response of Flexibly-Connected Steel Frames
The response of typical low-rise steel building frames designed by the 'Type 2 Construction' method to moderate earthquakes is examined. Such frames are often...

Brace Connections for Ductility
Influence of connection design on the seismic behavior of welded bracing members made of double channels is studied in this paper. Shortcomings of commonly used connection details as per...
