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 ... -
Impact Pressure and Forces on a Vertical Wall with Different Types of Parapet
(ASCE, 5/1/2021)This paper will discuss the variations in wave loads on a vertical seawall structure due to the addition of parapets. A 1:8 model scale experiments on a wall with parapets will be carried out. The models will be tested for ... -
Vertical Bearing Behavior of Monopod Caisson Foundation in Sandy Soils
(ASCE, 7/1/2021)This paper presents the results of numerical investigation on the vertical bearing behavior of monopod caisson foundations embedded in sandy soils and supporting offshore wind turbines. The effects of embedment depth and ... -
Water Exchange of Nontidal Estuarine Coastal Vistula Lagoon with the Baltic Sea
(ASCE, 7/1/2021)The objective of the study is to present the main morphometric features of the inner sand bar of the nontidal Vistula Lagoon, to obtain actual data on the water exchange of the lagoon with the Baltic Sea, to compare the ... -
Automatic Calibration of Bed Friction Coefficients to Reduce the Influence of Seasonal Variation: Case of the Gironde Estuary
(ASCE, 5/1/2021)An automatic procedure to identify the bed friction coefficient is tested on a 2D hydrodynamic model of the Gironde estuary (France). The proposed procedure involves an optimization algorithm based on evolution strategy, ... -
Enhancing the Erodibility of Cohesive Sediments by Applying Mechanical Vibrations
(ASCE, 5/1/2021)The efficiency of dredging, whether with a cutter suction dredger or hydraulic flushing, is closely related to the erodibility of the sediments. It is found that the erodibility of cohesive sediments, which is affected by ... -
Asymptotic Determination of the Liquefaction Depth for Short and Long Water Waves
