Turbulence Spectrum Around a Suspended Cylinder with Vertical Endplate Effects to Enhance VIVACE Strength
(ASCE, 9/1/2021)Alternating vortex formation on a horizontal suspended cylinder depends largely on flow turbulence causing its vibration. This vibration is known as “vortex-induced vibration” that leads to a power-harnessing device such ... -
Cost-Effective Marine Fender Design Using an Elastoplastic Support Element: An Investigation
(ASCE, 9/1/2021)This manuscript investigates the potential cost savings of installing a steel elastoplastic element in series, structurally, with a commercial rubber marine fender. Along with cost savings, the results also provide insight ... -
Hydrosedimentological Response to Estuarine Deepening: Conceptual Analysis
(ASCE, 9/1/2021)This paper describes the effects of anthropogenic deepening of tidal rivers in a conceptual way, with focus on tidal distortion and the residual transport of coarse sediment, driven by asymmetries in peak velocity. The ... -
Multifaceted Approach of Assessing Channel Design through Ship Simulations in Mobile Harbor, Alabama
(ASCE, 9/1/2021)Recently, Mobile Harbor, Alabama, experienced an increase in vessel size and traffic, which resulted in navigation inefficiencies. This prompted a navigation improvement study that included ship simulations to assess ... -
Waterway Engineering Applications of Automatic Identification System Data along the Mississippi River and at Lock Structures
(ASCE, 9/1/2021)The USACE, St. Louis District, is responsible for maintaining navigation channels along with multiple lock and dam structures on the Mississippi River, a vital inland waterway that carries millions of tons of commodities ... -
Experimental Investigation of a Moored, Circular Pipe Breakwater
(ASCE, 9/1/2021)Floating breakwaters are commonly used for shoreline protection in coastal areas and may offer a relatively cost-effective method for embankment protection in irrigation reservoirs. This study explored the potential use ... -
Behavior of Flexible Pintles for Miter Gates
(ASCE, 9/1/2021)The United States Army Corps of Engineers assumes that horizontally framed miter gates thrust into lock chamber walls under hydraulic head. However, in many gates the bottom hinge, a fixed pintle, interrupts this thrusting ... -
Observations on Floc Settling Velocities in the Tamar Estuary, United Kingdom
(ASCE, 9/1/2021)Measurements in the mesotidal Tamar estuary (UK) reported previously indicate a dependence of the floc settling velocity on the shear rate and the suspended fine sediment concentration or volume fraction. Typical ... -
Evaluation Techniques for the Beneficial Use of Dredged Sediment Placed in the Nearshore
(ASCE, 9/1/2021)Maintaining navigable waterways through dredging is vital to society and the economy, especially as global transport and cargo loads increase. Decision makers require rapid techniques to evaluate potential placement ... -
Observation of Sea Ice Drift Characteristics with Marine Radar Images on an Offshore Platform in the Bohai Sea
(ASCE, 7/1/2021)Radar images can be employed to examine features of the ice surface and to determine ice drift. In the winter of 2012–2013, sea ice drift in the Bohai Sea was monitored using a marine radar system installed on an offshore ... -
Cross-Shore Sediment Transport for Modeling Long-Term Shoreline Evolution
(ASCE, 7/1/2021)A process-based parametric closure model for estimating cross-shore sediment transport (CST) rate has been developed for simulating long-term shoreline evolution. The formulations of this closure model include calculations ... -
Calculation Model for Multiple Breaking Waves and Wave-Induced Currents on Very Gentle Beaches
(ASCE, 9/1/2021)Multiple wave breaking and wave-recovery processes are typical phenomena of wave motions observed on very gentle coastal beaches and have not been accounted for in previous models for the calculation of wave height and ... -
Modeling of Soft Cliff Erosion by Oblique Breaking Waves during a Storm
(ASCE, 7/1/2021)Soft cliff (bluff) erosion during a storm is investigated using available wave basin data and a cross-shore numerical model for dune erosion. The measured cliff recession rates under oblique breaking waves for cliffs built ... -
Installation of Novel Suction Bucket Foundation with New Modular Geometry in a Large-scale Set-up
(ASCE, 7/1/2021)This paper investigates a modular bucket foundation design developed for large offshore wind turbines. Instead of the regular round shape, the modular bucket consists of trapezoidal profiles bolted together and additional ... -
Simulation-Based Performance Assessment Framework for Optimizing Port Investment
(ASCE, 7/1/2021)This paper demonstrated a new framework for port investment optimization that includes a three-stage process. First, a performance-based approach was applied to determine the margins of ship responses under external impacts ... -
Failure Envelopes for Combined Loading of Skirted Foundations in Layered Deposits
(ASCE, 7/1/2021)A robust and integrated interpretation of soil data from field investigations can provide valuable insights into the important role of soil deterioration following the installation of suction caissons. Therefore, a field ... -
Framework for Dealing with Uncertainty in the Port Planning Process
(ASCE, 5/1/2021)Ports are complex engineering systems that have always been evolving to satisfy the new or changing demands of stakeholders. However, the ever-growing complexity in port sectors in a volatile environment creates a high ... -
