Multiple Approaches to Numerical Modeling of Container Ship Squat in Confined Water
(ASCE, 2020)Various unsteady Reynolds-averaged Navier–Stokes (URANS) modeling techniques to predict container ship squat in confined water are investigated and compared in this study to assess the suitability of each modeling technique. ... -
Overland Wave Propagation and Load Distribution among Arrays of Elevated Beachfront Structures
(ASCE, 2020)A series of laboratory experiments and high-fidelity numerical modeling were conducted to study the effects of the lowest floor elevation on the flow and loading patterns resulting from the overland propagation of a solitary ... -
Field Measurements in the Kiel Canal, Germany: Ship Waves, Drawdown, and Sediment Transport
(ASCE, 2020)Ship waves and ship-induced flows are the main hydrodynamic loads on waterway beds and embankments. However, the underlying physical processes are not yet understood fully. Recent field measurements, conducted in the Kiel ... -
Artificial Neural Network Prediction of Overtopping Rate for Impermeable Vertical Seawalls on Coral Reefs
(ASCE, 2020)An artificial neural network (ANN) tool trained using a backpropagation algorithm was developed to predict the overtopping rate of impermeable vertical seawalls on coral reefs. The training database was produced from ... -
Theoretical Analysis of an Asymmetric Offshore-Stationary Oscillating Water Column Device with Bottom Plate
(ASCE, 2020)To give high performance over a broader wave frequency range and enable the multipurpose utilization of marine structures, an asymmetric offshore-stationary oscillating water column device with an outstretched bottom plate ... -
Stability of Composite Breakwaters under Tsunami Attack
(ASCE, 2020)Breakwaters are effective structures for mitigating tsunami-induced damage. However, pieces of the breakwater can be displaced by the turbulent tsunami flow, which undermines the stability of the breakwater and reduces its ... -
Waves in Collections of Circular Shoals and Bathymetric Depressions
(ASCE, 2020)New approximate analytic solutions are developed to study wave propagation through collections of coastal features. Solutions are developed for circular shoals formed by a submerged cylinder with water depth shallower than ... -
Wave Runup Loading Behind a Semipermeable Obstacle
(ASCE, 2020)This paper describes an investigation of the interaction of breaking solitary wave runup with a two-dimensional semipermeable (vegetated) obstacle and the resulting wave loading on a downstream cylinder. The OpenFOAM model, ... -
Fluxes of Sediment Beneath Floating Silt Screens due to Density Gradients and Screen Motion
(ASCE, 2020)Floating silt screens are widely applied to confine and control turbidity plumes and sedimentation due to dredging activities. Their efficient deployment requires detailed knowledge of the ambient hydrodynamic conditions. ... -
Fluid Mud Induced by Super Typhoon and Fluvial Flood in a Deep-Dredged Waterway of Xiamen, China
(ASCE, 2020)The mechanisms of fluid mud formation and its characteristics are far from clear in the deep-dredged waterway in Xiamen estuarine bay. Some experiments were conducted in the muddy estuarine bay of Xiamen when Super Typhoon ... -

(ASCE, 2020)An advanced fully hydro- and morphodynamic two-dimensional horizontal (2DH) numerical model, describing the processes of nonlinear wave propagation, sediment transport, and morphological changes and being suitable for the ... -
Numerical and Centrifuge Modeling of Gravity Wharf Structures Subjected to Seismic Loading
(ASCE, 2020)Gravity wharf (GW) structures are gaining popularity in new port constructions, as well as expanding existing ports. When such structures are located on saturated alluvial seabed, their seismic performance needs to be ... -
Modeling Shoreline Changes in Northwest Portugal Using a Process-Based Numerical Model: COAST2D
(ASCE, 2020)The coastal stretch between Vagueira and Praia de Mira, northern Portugal, is subject to high-energy wave conditions. At the same time, the shoreline is a main contributor to the local economy, extensively due to tourism. ... -
Tsunami-Like Wave-Induced Lateral and Uplift Pressures and Forces on an Elevated Coastal Structure
(ASCE, 2020)A large-scale physical model was constructed in the Large Wave Flume of Hinsdale Wave Research Laboratory (HWRL) at Oregon State University to develop a dataset of measured pressures and forces acting on an elevated, coastal ... -
Probabilistic Assessment of Storage Tanks Subjected to Waterborne Debris Impacts during Storm Events
