Mining Marine Vessel AIS Data to Inform Coastal Structure Management
(ASCE, 2020)This study demonstrates the use of a multiyear country-scale automatic identification system (AIS) data set to partition a nationwide portfolio of navigation structures managed by the US Army Corps of Engineers (USACE) ... -
Application of Genetic Algorithm for Optimum Hydrodynamic Performance of Twin Pontoon Floating Breakwater
(ASCE, 2020)The lateral separation ratio (S/D) between the twin pontoons of a floating breakwater (TPFB) is one of the prominent factors that attenuate wave energy transmission and reflection. In fact, a numerical investigation of ... -
Wave-Induced Liquefaction and Floatation of a Pipeline in a Drum Centrifuge
(ASCE, 2020)This paper discusses the floatation of a buried pipe in association with wave-induced liquefaction of sand beds. Centrifuge wave tests in a drum channel were performed with viscous scaling introduced such that the time-scaling ... -
Multiple Debris Impact Loads in Extreme Hydrodynamic Conditions
(ASCE, 2020)Video footage from the 2004 Indian Ocean and 2011 Tohoku tsunamis showed large quantities of debris entrained within the inundating flows. Such extreme debris conditions can lead to a high probability for multiple impacts ... -
Analysis and Verification of an Optimal Design Solution for Rubble Mound Breakwaters Considering Interactions of Failure Modes
(ASCE, 2020)As an essential coastal structure, a breakwater is generally designed to be stable and reliable during its lifetime. With respect to stability, failure modes usually are statistically independent. However, the interaction ... -
Comparison of Revetment and Sill in Reducing Shore Erosion and Wave Overtopping
(ASCE, 2020)A laboratory experiment was conducted in a wave flume to compare sand beach profile evolution and wave overtopping of a sand berm for the three cases of (1) no structure, (2) a stone revetment protecting the steep ... -
Development of Stability Formulas for Rock Armor and Tetrapods Using Multigene Genetic Programming
(ASCE, 2020)Stability formulas for rock armor and Tetrapods were developed using multigene genetic programming, which is one of the machine learning methods. The developed formulas are shown to be more accurate than previous empirical ... -
Wave Attenuation by Multiple Outer Porous Barriers in the Presence of an Inner Rigid Cylinder
(ASCE, 2020)The wave forces acting on a rigid cylinder are investigated in the presence of multiple outer porous cylindrical barriers by assuming the linear water wave theory. A Bessel series solution is obtained for the boundary value ... -
Impact of a Quayside Floating System on Overtopping
(ASCE, 2020)This paper reports results of the impact of a quayside floating system on overtopping. The approach is experimental and analytical. Rectangular floaters in heave motion were considered at various distances from a vertical ... -
Numerical Investigation of Dynamic Pipe–Soil Interaction on Electrokinetic-Treated Soft Clay Soil
(ASCE, 2020)Researchers have underscored the importance for a pipeline to safeguard against adverse effects resulting from its displacement in the vertical, axial, and lateral directions because of the low shear strength of the soil. ... -
Experimental Evaluation of Wave Transmission and Dynamics of Double-Row Floating Breakwaters
(American Society of Civil Engineers, 2019)Floating breakwaters are recognized as effective wave-attenuation structures for protecting shorelines and marine facilities. However, most common single-row floating breakwaters are unable to effectively attenuate the ... -
Spatial Impulse Wave Generation and Propagation
(American Society of Civil Engineers, 2019)Rapid landslides into water bodies may generate massive water waves posing a threat to riparian settlements and infrastructure. These waves are referred to as impulse waves and exhibit tsunami-like characteristics. The ... -
Influence of Grain Size on Sediment Transport during Initial Stages of Horizontal Dam Break–Type Flows
(American Society of Civil Engineers, 2019)The influence of grain size on sediment transport during the initial stages of dam break–type flows over horizontal mobile sediment beds was investigated through dimensional analysis and experiments. A new dimensional ... -
