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
(ASCE, 5/1/2021)In this work, an analytical solution that models the dynamic response of a poroelastic soil, induced by the action of water waves in a stratified fluid, is obtained. We propose a reduction of the generalized governing ... -
Influence of Orientation and Arrangement of Structures on Tsunami Impact Forces: Numerical Investigation with Smoothed Particle Hydrodynamics
(ASCE, 5/1/2021)This paper explores the influence of onshore structures' orientations and arrangements during a tsunami impact using the numerical method of smoothed particle hydrodynamics (SPH). Observations from previous tsunami events ... -
Ambient Entrainment Mechanisms of Partially Unconfined Turbidity Currents Interacting with a Continuous Rigid Obstacle
(ASCE, 5/1/2021)In this study, the entrainment mechanisms of unconfined turbidity currents that interact with a linear rectangular obstacle will be investigated and compared with confined studies. Laboratory experiments will be performed ... -
Acoustic Measurement of Ship Wave–Induced Sediment Resuspension in a Large River
(ASCE, 3/1/2021)This paper presents a proof of concept that acoustic velocity and backscatter intensity measurements can provide essential information on ship wave–induced sediment transport processes in the littoral zone of a large river. ... -
Feasibility of Very Large Floating Structure as Offshore Wind Foundation: Effects of Hinge Numbers on Wave Loads and Induced Responses
(ASCE, 5/1/2021)Floating offshore wind is a rapidly growing technology that is attracting global interest. To date, most of the demonstrated concepts for offshore floating wind are based on a simple one turbine–one platform system, which ... -
Transport of Placed Dredged Material in Surf and Nearshore Zone
(ASCE, 5/1/2021)Driven by waves, water surface elevation, and wind conditions, a coupled wave, hydrodynamic, and sediment transport modeling system was developed to investigate the transport of placed dredged material in the surf and ... -
Tsunami Impact on a Detached Breakwater: Insights from Two Numerical Models
(ASCE, 3/1/2021)Tsunami waves are often very energetic and therefore pose a significant threat to coastal structures. However, most coastal defenses such as detached breakwaters are designed to protect against storm waves, with the ... -
Effects of Island Topography on Storm Surge in Taiwan Strait during Typhoon Maria
(ASCE, 3/1/2021)In July 2018, Super Typhoon Maria moved in the northwestward direction, passed by the northern tip of Taiwan Island, and severely impacted the coasts along Fujian and Zhejiang Provinces, China. In this paper, the storm ... -
Modeling Swash Zone Hydrodynamics Using Discontinuous Galerkin Finite-Element Method
(ASCE, 3/1/2021)A two-dimensional numerical model for the solution of the nonlinear shallow water equations (NSWEs) using the discontinuous Galerkin finite element method (DGFEM) is presented. A new adaptation of the thin-film approach ... -
Effects of Sea Level Rise on Storm Surge Flooding and Current Speeds in New Hampshire Estuaries
(ASCE, 3/1/2021)The effects of sea level rise on storm surge energy transformation and flood and ebb current magnitudes are examined in two distinct New Hampshire estuarine systems. The Great Bay estuary is characterized by strong tidal ... -
NavTEL: Open-Source Decision Support Tool for Ship Routing and Underkeel Clearance Management in Estuarine Channels
(ASCE, 3/1/2021)NavTEL is a new decision support tool for the short-term (36 h) planning of ship routes and the management of underkeel clearance in estuarine navigation channels. NavTEL uses a deterministic method and is coupled with the ... -
Effects of Fines Content and Relative Density on Erosion and Recession of Predominantly Sandy Beach–Bluff System
(ASCE, 1/1/2021)Exploratory experiments including a series of flume and geotechnical tests were conducted to assess the effects of fines content and relative density on the erosion and recession of predominantly sandy beach and bluff. The ... -

(ASCE, 3/1/2021)The salinity distribution in the estuarine channel network of a partially mixed estuary was investigated by quantifying salt intrusion length and stratification with response to tidal circulation, seasonal variation, ... -
Engineering Lessons from September 28, 2018 Indonesian Tsunami: Scouring Mechanisms and Effects on Infrastructure
(ASCE, 3/1/2021)The September 28, 2018 earthquake and tsunami, which occurred north of Palu City, Indonesia, attracted widespread interest from the scientific community due to the unusually large tsunami that occurred after a strike-slip ... -
Influence of Edge Waves on Tsunami Characteristics along Kujukuri Beach, Japan
(ASCE, 1/1/2021)The 2011 Tohoku Earthquake and Tsunami generated a massive tsunami that devastated Kujukuri Beach in Chiba Prefecture, Japan. The possibility that edge waves were involved in the propagation mechanism of the tsunami was ... -
Evaluation Methodology of Laminar-Turbulent Flow State for Fluidized Material with Special Reference to Submarine Landslide
