Nonhydrostatic Numerical Modeling of Fixed and Mobile Barred Beaches: Limitations of Depth-Averaged Wave Resolving Models around Sandbars
(ASCE, 2022-1-1)Along sandy coastlines, submerged, shore-parallel sandbars play an essential role in shoreline morphology by dissipating wave energy through depth-induced wave breaking. While wave breaking and sediment transport around ... -
Southwest Pass Sedimentation and Dredging Data Analysis
(ASCE, 2022-3-1)The United States Army Corps of Engineers (USACE) maintains the Mississippi River, Baton Rouge, Louisiana, to the Gulf of Mexico Project as part of its Navigation mission to enable safe, reliable, and cost-effective marine ... -
Experimental Assessment of Hydrodynamic Coefficients for a Heave Plate Executing Pitch Oscillations
(ASCE, 2022-1-1)A submerged oscillating heave plate is utilized as a mechanism in some marine structures for vibration reduction. Quantifying the hydrodynamic properties in axial (heave) oscillations has been extensively archived in ... -
Hydrodynamic Characteristics of Concave Front Pile-Supported Breakwaters with a Tubular Wave Screen
(ASCE, 2022-1-1)Concave front pile-supported breakwaters, namely, Galveston wall-shaped pile-supported breakwater (GS-PSB) and circular cum parabola-shaped pile-supported breakwater (CPS-PSB), have proven to be more effective in dissipating ... -
Quantitative Composition of Drag Forces on Suspended Pipelines from Submarine Landslides
(ASCE, 2022-1-1)The impact forces of submarine landslides (i.e., non-Newtonian fluids) on oil and gas pipelines, especially the most dangerous drag force, are of great significance in the design of deep-water pipelines. The drag force is ... -
Estimating Extreme High Still Water Levels in North San Francisco Bay: Comparison of Annual Maxima Method with Direct and Indirect Methods
(ASCE, 2022-1-1)Extreme high still water levels (EHSWLs) are calculated at four tide stations located along North San Francisco Bay for a range of return periods. The observed hourly still water level varying from 7 years to 122 years ... -
Fluid–Vehicle–Tunnel Coupled Vibration Analysis of a Submerged Floating Tunnel Based on a Wake Oscillator Model
(ASCE, 2022-1-1)The submerged floating tunnel (SFT) is a newly developed traffic structure for crossing the long waterway. On the basis of the vehicle–tunnel coupled vibration, the vortex-induced effect of the SFT in the water flow field ... -
Incorporating Water Quality Analysis into Navigation Assessments as Demonstrated in the Mississippi River Basin
(ASCE, 9/1/2021)A description of historical and ambient water quality conditions is often required as part of navigational studies. This paper describes a series of tools developed by the USGS that can aid navigation managers in developing ... -
Variation of Wave Forces Along a Semi-Infinite Breakwater Due to Wave Diffraction
(ASCE, 9/1/2021)This paper investigates distribution of wave forces along a semi-infinite breakwater considering wave diffraction using the analytical solutions derived from linear wave theory. It is found that the total wave amplitude ... -
Effects of Different Geometric Parameters of Complex Bridge Piers on Maximum Scour Depth: Experimental Study
(ASCE, 9/1/2021)This research experimentally investigated local scour depth around complex bridge piers in a clear-water condition. The term “complex pier” is used to define a bridge pier composed of three different sections: a column, ... -
Formulating Wave Overtopping at Vertical and Sloping Structures with Shallow Foreshores Using Deep-Water Wave Characteristics
(ASCE, 11/1/2021)The state-of-the-art formulas for mean wave overtopping (q) assessment typically require wave conditions at the toe of the structure as input. However, for structures built either on land or in very shallow water, obtaining ... -
Approaches in Scaling Small-Scale Experiments on the Breaking Wave Interactions with a Vertical Wall Attached with Recurved Parapets
(ASCE, 11/1/2021)The breaking wave interactions on a vertical wall with three different recurved parapets were examined in two different scales (1:1 and 1:8) to study the scale effects. A similar testing condition with that of the large ... -
Resistance and Economic Speed of Ships and Tows in Inland Waterways
(ASCE, 11/1/2021)The resistance of commercial vessels in inland waterways is an essential and widely investigated problem. Depending on vessel and channel shape and size, many empirical equations were developed in the past to determine the ... -
Effective Flood Control Method in River Downstream Affected by Tidal Effect Using Optimal Operation of Estuary Barrage
