Fully Nonlinear Boussinesq-Type Equations for Waves and Currents over Porous Beds
Publisher: American Society of Civil Engineers
Abstract: The paper introduces a complete set of Boussinesq-type equations suitable for water waves and wave-induced nearshore circulation over an inhomogeneous, permeable bottom. The derivation starts with the conventional expansion ...
Modeling Attenuation of Storm Surge over Deformable Vegetation: Parametric Study
Publisher: American Society of Civil Engineers
Abstract: This paper presents a parametric study on storm-surge reduction by flexible vegetation in coastal wetlands under idealized prototype conditions. A vegetation-induced flow resistance model that considers flow depth, flow ...
Spectral Collocation Model for Solitary Wave Attenuation and Mass Transport over Viscous Mud
Publisher: American Society of Civil Engineers
Abstract: In this paper, wave attenuation and mass transport of a water-mud system due to a solitary wave on the free surface is modeled by using the Chebyshev-Chebyshev collocation spectral method for spatial discretization and a ...
Numerical Modeling of Surface Waves over Submerged Flexible Vegetation
Publisher: American Society of Civil Engineers
Abstract: This paper presents a coupled wave–vegetation model for simulating the interaction between water waves and submerged flexible plants. The balance of forces for the vegetation motion includes buoyancy, damping, stiffness ...
Theoretical Models for Wave Energy Dissipation Caused by Vegetation
Publisher: American Society of Civil Engineers
Abstract: The paper presents theoretical and numerical analyses of random wave attenuation attributable to vegetation. Existing models based on Rayleigh distribution of wave heights are critically examined followed by the development ...
Effects of Triad Interactions on Wave Attenuation by Vegetation
Publisher: American Society of Civil Engineers
Abstract: Wave attenuation in vegetated shallow water is mainly attributed to actual drag-induced dissipation and near-resonant triad interactions. The latter is neglected in existing theoretical models for vegetation-induced ...
Attenuation of Nonlinear Waves by Rigid Vegetation: Comparison of Different Wave Theories
Publisher: American Society of Civil Engineers
Abstract: This study investigates the performances of theoretical wave attenuation models in predicting vegetation-induced wave decay. The existing theoretical models are all based on linear wave theory, which cannot describe nonlinear ...
Hydrodynamic Investigation of Coastal Bridge Collapse during Hurricane Katrina
Publisher: American Society of Civil Engineers
Abstract: A number of U.S. coastal bridges have been destroyed by hurricanes, including three highway bridges in Mississippi and Louisiana during Hurricane Katrina (2005). This paper addresses three fundamental questions on the ...
Countermeasure of Air Venting Holes in the Bridge Deck–Wave Interaction under Solitary Waves
Publisher: American Society of Civil Engineers
Abstract: This paper discusses three fundamental questions on the bridge deck-wave interaction: (1) are there countermeasures to mitigate the wave forces on the bridge decks? (2) what is the working mechanism of the ...
Prediction of Solitary Wave Forces on Coastal Bridge Decks Using Artificial Neural Networks
Publisher: American Society of Civil Engineers
Abstract: This study proposes an alternative and competitive methodology for predicting solitary wave forces on coastal bridge decks using artificial neural networks (ANNs). It is imperative to accurately predict the on-deck wave ...
