New Queuing Theory Applied to Port Terminals and Proposal for Practical Application in Container and Bulk Terminals
(ASCE, 1/1/2020 1)Queueing theory has been used in port management since the early 60s as a support, among others, to determine the optimal number of berths based on the occupation rate of the berths and the expected waiting time for vessels ... -
Local Scour Mechanism around Dynamically Active Marine Structures in Noncohesive Sediments and Unidirectional Current
(ASCE, 1/1/2020 1)This paper sheds light on the mechanism of post equilibrium sea bed scour around dynamically active marine structures such as wind turbines. Exposure of a fully developed scour hole (at equilibrium state) around a wind ... -
Simple Approach to Long-Term Morphodynamics of the River Delta Applied to the Vistula River Outlet
(ASCE, 1/1/2020 1)This paper deals with the evolution of the engineered mouth of the Vistula River, Poland, influencing the growth of its delta. The considered delta is a coastal form typical for semiclosed nontidal seas, like the Baltic. ... -
Centrifuge Modeling on Performance of Plumb-Pile-Supported Wharf under Yard-Heaped Loads
(ASCE, 2020)This paper presents the results of a centrifuge model test performed to study the behavior of a plumb-pile-supported wharf under yard-heaped loads. A bent composed of a slab, girders, and six rows of equally spaced plumb ... -
Considering Future Sea Level Change in Maritime Infrastructure Design: A Survey of US Engineers
(ASCE, 2020)Seaports are particularly vulnerable to coastal hazards such as hurricanes and flooding due to their location. Sea level change (SLC) can magnify the impacts of these coastal hazards, threatening the resilience of ports. ... -
Tsunami-Like Wave Forces on an Elevated Coastal Structure: Effects of Flow Shielding and Channeling
(ASCE, 2020)During a tsunami event, neighboring structures can significantly influence the forces experienced by an individual structure within an urban community. To assess the effects of adjacent structures on the resulting fluid ... -
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 ... -
