Remaining Capacity of Low-Crested Rubble Mounds Damaged by Breaking Waves in Surf Zone
(ASCE, 2022/11/01)The rehabilitation timing of a damaged rubble mound structure depends on the remaining capacity of the deteriorated structure. A laboratory experiment was conducted in a wave flume to measure the remaining capacity of a ... -
Evaluation of Total Sediment Transport Model in the Simulation of Morphodynamics in Two Different Hydrodynamic Settings
(ASCE, 2022/11/01)The bed level change in rivers and estuaries due to several dynamic parameters such as tide, waves, river discharge, and wind is a common problem. The current practice is to predict the changes through numerical modeling ... -
Nearshore Vertical Pore Pressure Gradients and Onshore Sediment Transport under Tropical Storm Forcing
(ASCE, 2022/11/01)Colocated sediment pore pressures at depths of approximately 0.02 and 0.22 m below the sand surface and near-bed water velocities were measured for approximately 2 weeks in approximately 1 m mean water depth on an ocean ... -
Investigation of Momentum Correction Factor in the Swash Flow
(ASCE, 2022/11/01)Swash flows are commonly modeled using the nonlinear shallow water equations (NSWEs). In the derivation of the NSWEs, directly from depth-averaging the Navier–Stokes equations, a so-called momentum correction factor, β, ... -
Modeling of Coastal Erosion in Exposed and Groin-Protected Steep Beaches
(ASCE, 2022/11/01)Process-based models are suitable tools for reproducing storm-driven erosion. However, their performance has been mainly examined on mild-slope sandy beaches and their use on steep beaches still represents a challenge. ... -
Bragg Scattering of Surface Gravity Waves by an Array of Surface-Piercing Variable Porosity Barriers
(ASCE, 2022/11/01)The scattering of gravity waves by vertically staggered multiple porous barriers having variable porosity is analyzed within the framework of linearized water wave theory in two dimensions. The barriers are assumed to ... -
Role of Armor Roughness in Overtopping Response of Upgraded Multilayer Rubble Mound Breakwaters
(ASCE, 2022/07/15)Wave overtopping needs to be estimated in the design of rubble mound breakwaters, because a high overtopping rate could reduce the capacity and functionality of the structure. The existing formulas, among others, provide ... -
Wave Interaction with Horizontal Multilayer Porous Plates
(ASCE, 2022/07/07)An analytical model for the horizontal multilayer porous plates has been developed based on linear potential theory. Energy dissipation across the horizontal porous plates is considered with an equivalent linearized porous ... -
Dredging Volume Estimation and Dredging Timing for Waterway Maintenance: A Case Study Using a Depth-Averaged Hydrosediment–Morphodynamic Model with Transient Dredging Effects
(ASCE, 2022/06/24)Dredging is an important measure for maintaining sufficiently high water depths in waterways. However, previous dredging studies have rarely focused on modeling the transient effects of dredging activities on bed evolutions. ... -
Hydrodynamics and Associated Scour around a Free-Standing Structure Due to Turbulent Bores
(ASCE, 2022/06/24)Forensic engineering field surveys conducted in the aftermath of large-scale tsunamis documented the presence of deep local scour holes around structures caused by extreme inundation occurring during such events. The ... -
Effects of Shell Hash on Friction Angles of Surficial Seafloor Sediments near Oysters
(ASCE, 2022/06/29)Oysters are hypothesized to affect the shear strength of nearby surficial seafloor sediment as fragments of oyster shells (shell hash) are typically more angular relative to sand particles alone, among other differences. ... -
Conceptual Model for the Operational Performance of the Container Terminals in India
(ASCE, 2022/05/16)In the upcoming years, container terminals in India can attain more substantial throughput targets by exploiting their untapped potential of throughput. Numerous factors may affect the existing terminals’ ability to perform ... -
Determination of the Optimal Groin Length on a Sandy Multibar Shore of a Nontidal Sea: Case Study of the Hel Peninsula, Poland, South Baltic Sea
(ASCE, 2022/05/11)In this paper, we present a simple theoretical method of determining the optimal groin length on a sandy multibar shore of a nontidal sea. Example computations for the seashore of the Hel Peninsula (Poland, south Baltic ... -
Numerical Evaluation of Optimal Sizes of Wells Turbine and Chamber of a Cluster of Oscillating Water Columns Integrated into a Breakwater on the Southern Brazilian Coast
(ASCE, 2022/05/03)This paper describes a numerical evaluation of optimal sizes of a Wells turbine and chamber cross section to be used in a cluster of an oscillating water column (OWC) wave energy converter device. The FLUENT numerical ... -
A Coastal Defense Work Plan 40 Years Later: Review and Evaluation of the Espinho Case Study in Portugal
(ASCE, 2022/05/19)In the 1980s, a coastal defense plan was prepared for a 110-km long stretch of the northwest Portuguese coast, from the Leixões harbor to Cape Mondego. This paper revisits the plan for the location of the Espinho beach and ... -
Directional Infragravity Waves Induced by Bichromatic and Bidirectional Waves: Theoretical Approach and Experimental Affirmation
