Developing Closed-Form Equations of Maximum Drag and Moment on Rigid Vegetation Stems in Fully Nonlinear Waves
Publisher: ASCE
Abstract: Coastal wetlands act as natural buffers against wave energy and storm surges. In the course of energy dissipation, vegetation stems are exposed to wave action, which may lead to stem breakage. An integral component of wave ...
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 ...
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 ...
Semianalytical Model of Depth-Integrated Vegetal Drag Force Based on Stokes Second-Order Wave Theory
Publisher: American Society of Civil Engineers
Abstract: The phase-averaged depth-integrated vegetal drag force (Fv) directly impacts the mean water level (MWL) change in vegetation. Evaluated from linear wave theory, Fv integrated along the submerged part of vegetation becomes ...
Preparation of 3D-Printed Concrete from Solid Waste: Study of the Relationship between Steel Slag Characteristics and Early Performance in 3D Printing
Publisher: American Society of Civil Engineers
Abstract: Using steel slag in architectural three-dimensional (3D) printing not only enhances its utilization efficiency but also significantly reduces cement consumption, thereby mitigating carbon emissions. This study evaluated ...
Atlantic Multidecadal Variability Response to External Forcing during the Past Two Millennia
Publisher: American Meteorological Society
Abstract: Atlantic multidecadal variability (AMV) is a cornerstone for decadal prediction and profoundly influences regional and global climate variability, yet its fundamental drivers remain an issue for debate. Studies suggest ...
