Dredging Volume Estimation and Dredging Timing for Waterway Maintenance: A Case Study Using a Depth-Averaged Hydrosediment–Morphodynamic Model with Transient Dredging Effects
(ASCE, 2022/06/24)Dredging is an important measure for maintaining sufficiently high water depths in waterways. However, previous dredging studies have rarely focused on modeling the transient effects of dredging activities on bed evolutions. ... -
Hydrodynamics and Associated Scour around a Free-Standing Structure Due to Turbulent Bores
(ASCE, 2022/06/24)Forensic engineering field surveys conducted in the aftermath of large-scale tsunamis documented the presence of deep local scour holes around structures caused by extreme inundation occurring during such events. The ... -
Effects of Shell Hash on Friction Angles of Surficial Seafloor Sediments near Oysters
(ASCE, 2022/06/29)Oysters are hypothesized to affect the shear strength of nearby surficial seafloor sediment as fragments of oyster shells (shell hash) are typically more angular relative to sand particles alone, among other differences. ... -
Conceptual Model for the Operational Performance of the Container Terminals in India
(ASCE, 2022/05/16)In the upcoming years, container terminals in India can attain more substantial throughput targets by exploiting their untapped potential of throughput. Numerous factors may affect the existing terminals’ ability to perform ... -
Determination of the Optimal Groin Length on a Sandy Multibar Shore of a Nontidal Sea: Case Study of the Hel Peninsula, Poland, South Baltic Sea
(ASCE, 2022/05/11)In this paper, we present a simple theoretical method of determining the optimal groin length on a sandy multibar shore of a nontidal sea. Example computations for the seashore of the Hel Peninsula (Poland, south Baltic ... -
Numerical Evaluation of Optimal Sizes of Wells Turbine and Chamber of a Cluster of Oscillating Water Columns Integrated into a Breakwater on the Southern Brazilian Coast
(ASCE, 2022/05/03)This paper describes a numerical evaluation of optimal sizes of a Wells turbine and chamber cross section to be used in a cluster of an oscillating water column (OWC) wave energy converter device. The FLUENT numerical ... -
A Coastal Defense Work Plan 40 Years Later: Review and Evaluation of the Espinho Case Study in Portugal
(ASCE, 2022/05/19)In the 1980s, a coastal defense plan was prepared for a 110-km long stretch of the northwest Portuguese coast, from the Leixões harbor to Cape Mondego. This paper revisits the plan for the location of the Espinho beach and ... -
Directional Infragravity Waves Induced by Bichromatic and Bidirectional Waves: Theoretical Approach and Experimental Affirmation
(ASCE, 2022/05/19)This work presents a theoretical discussion and experimental results about the directional bound waves generated by second-order nonlinear interaction between two noncollinear wave trains. Research focus is set on presence, ... -
Quantifying Wide-Body Vessel Navigation Delay in Narrow Waterways: A Case Study at the Houston Ship Channel
(ASCE, 2022/05/10)In narrow waterways, navigation restrictions are imposed on vessels based on beam and length to safely accommodate two-way traffic. Each transit in a narrow waterway can potentially generate delay for the rest of the vessels ... -
Finding the Bed Shear Stress on a Rough Bed Using the Log Law
(ASCE, 2022/04/29)The procedure commonly used to determine the friction velocity from a measured velocity profile in turbulent flow over a hydraulically rough bed is to fit the log law to the velocity profile and adjust the displacement ... -
Impacts of a Floating Structure on the Residence Time in a Poorly Flushed Estuary, Golden Horn
(ASCE, 2022-7-1)Pontoon bridges are preferable structures when bridges supported by piers are not economically feasible. However, bridges that are built on floating pontoons act as a barrier and can block water flow, thus affecting the ... -
Experimental Investigation of the Hydraulic Performance of Breakwater Structures with Geotextile Armor Units
(ASCE, 2022-5-1)Geotextile sand containers (GSCs) gained popularity recently as a modern age coastal protection measure. Its usability as an ecofriendly alternative for traditional breakwaters overcomes issues such as scarcity and quarrying ... -
Experimental Study to Determine Forces Acting on Starbloc Armor Units and Velocities Occurring in a Single-Layer Rubble Mound Breakwater under Regular Waves
(ASCE, 2022-7-1)A series of two-dimensional (2D) model tests were performed to investigate loads acting on a new artificial block (Starbloc) within a breakwater during regular waves. This block is designed as an interlocking single-layer ... -
Trends in the Climatology of Winter Wind Wave Heights in a Back-Barrier Bay in Western North Atlantic Ocean
