Probabilistic Assessment of Storage Tanks Subjected to Waterborne Debris Impacts during Storm Events
(ASCE, 2020)Probabilistic models to evaluate the vulnerability of aboveground storage tanks (ASTs) subjected to waterborne debris impacts during storm surge events are currently lacking, despite evidence of debris-induced damage during ... -
Revisiting Longshore Sediment Transport Formulas
(ASCE, 2020)Longshore sediment transport (LST) prediction is still a challenging task in coastal engineering, due to complexity in affecting physical processes. There have been studies to develop tools to predict the LST rate, but ... -
Spreading and Deposition of Turbidity Currents: Application to Open-Water Sediment Disposal
(ASCE, 2020)A new two-phase box model is developed in this study for the prediction of a spatially varying turbidity current with sediments on a horizontal bottom. The turbidity current is segmented into small subvolumes to account ... -
New Prediction Formula for Pore Pressure Distribution inside Rubble-Mound Breakwater Core
(ASCE, 2020)A new prediction formula is proposed to determine wave-induced pore pressure height distribution inside the core of rubble-mound breakwaters. Existing observed field and experimental data in the literature have been examined, ... -
Erosion by Wave Action of Consolidated Cohesive Bottom Containing Cohesionless Sediment
(ASCE, 2020)The erosion processes of consolidated cohesive sediment under irregular breaking waves were formulated to predict the profile evolution of a cohesive sediment beach with a layer of sand. The cohesive sediment is eroded by ... -
Low-Temperature Rheological Behavior of Submarine Mudflows
(ASCE, 2020)Due to seawater intrusion, submarine sediments and slide masses routinely evolve into fluidized mudflows during long-distance migration and seriously endanger marine engineering facilities. However, few studies of the ... -
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 ... -
