Laboratory Measurements of Void Fraction and Turbulence in the Bore Region of Surf Zone Waves
Publisher: American Society of Civil Engineers
Abstract: Laboratory measurements of the instantaneous free surface, horizontal velocity, and void fraction fluctuations were made simultaneously for three cases of regular waves breaking on a plane slope. The data were reduced by ...
Kinematic Undertow Model with Logarithmic Boundary Layer
Publisher: American Society of Civil Engineers
Abstract: A new kinematic undertow profile model is developed to relate the mean horizontal velocity, bottom shear stress, and boundary layer thickness in a simple but general manner. The model combines a logarithmic profile in the ...
Statistical Modeling of Overtopping for Extreme Waves on Fixed Deck
Publisher: American Society of Civil Engineers
Abstract: A statistical model is developed to predict wave overtopping of extreme waves on a fixed deck. The probability density function for the volume of overtopping water is based on the truncated Weibull distribution with the ...
Water Level Observations and Short-Term Predictions Including Meteorological Events for Entrance of Galveston Bay, Texas
Publisher: American Society of Civil Engineers
Abstract: This paper shows that conventional harmonic analysis alone does not adequately predict the coastal water level variation at the entrance to Galveston Bay when strong meteorological forcing is present. The water level ...
Irregular Wave Reflection and Run‐Up on Rough Impermeable Slopes
Publisher: American Society of Civil Engineers
Abstract: Three irregular wave test runs were conducted to obtain detailed data on irregular wave reflection and run‐up on a 1:3 rough impermeable slope. The test results were also used to evaluate the capabilities and limitations ...
Effects of Vertical Variation in Vegetation Density on Wave Attenuation
Publisher: American Society of Civil Engineers
Abstract: A physical model experiment was used to investigate irregular wave attenuation through emergent vegetation with variations in stem heights. The experiment was conducted with six peak periods, six incident wave heights, and ...
Spatiotemporal Characteristics of Near-Bed Pressure Gradients on a Barred Beach
Publisher: American Society of Civil Engineers
Abstract: Observations of the cross-shore variations of pressure gradients measured on a fixed barred beach in a large-scale laboratory wave flume are presented in this paper. The wave-induced components (0.1–1.0 Hz) of the free ...
Hydrodynamic Characteristics of Pile-Supported Vertical Wall Breakwaters
Publisher: American Society of Civil Engineers
Abstract: This paper describes the hydrodynamic characteristics of a pile-supported vertical wall breakwater, the upper part of which is a vertical wall, and the lower part consisting of an array of vertical piles. For regular waves, ...
Hurricane Surge-Wave Building Fragility Methodology for Use in Damage, Loss, and Resilience Analysis
Publisher: ASCE
Abstract: Physics-based fragilities for damage, loss, and resilience analysis are needed to model a community to earthquakes, hurricane winds, tornados, or floods. Currently, most building flood fragilities such as those available ...
Laboratory Experiments of Vertical Cylinders Representative of Aboveground Storage Tanks Subjected to Waves
Publisher: ASCE
Abstract: This paper presents an overview of laboratory experiments of vertical cylinders representative of aboveground storage tanks (ASTs) subjected to waves. The main objective is to provide an experimental dataset for the ...
