Wave Interaction with Fluid Mud in Rectangular Trench
Publisher: American Society of Civil Engineers
Abstract: Wave interaction with fluid mud in a rectangular trench is studied theoretically based on small‐amplitude wave theory. The motion of fluid mud is modeled using the Voigt model for a viscoelastic medium. It is found that ...
Hydraulic and Contraction Scour Analysis of a Meandering Channel: James River Bridges near Mitchell, South Dakota
Publisher: American Society of Civil Engineers
Abstract: The two-dimensional (2D) depth-averaged river model Finite-Element Surface-Water Modeling System (FESWMS) was used to simulate the hydraulic conditions at a contracted bridge site. The site studied was the James River ...
Measurements of Water Surface Profile and Velocity Field at a Circular Pier
Publisher: American Society of Civil Engineers
Abstract: Flow around a 60-mm-diameter pier on a smooth bed was measured in an open-channel flume. By varying the approach flow velocity and water depth, a wide range of subcritical flow conditions was produced. Water surface elevation ...
Experimental Study of Particle Motion on a Smooth Bed under Shoaling Waves Using Particle Image Velocimetry
Publisher: American Society of Civil Engineers
Abstract: The motion of spherical particles (diameter 1.58 mm, specific gravity 2.5) on 2 and 3% plane slope was studied in a laboratory wave flume for shoaling wave conditions. The range of wave-height-to-water-depth ratio was
Wave Interaction with a Rectangular Trench
Publisher: American Society of Civil Engineers
Abstract: This study is related to the propagation of normally incident water waves past a submarine trench with a rectangular cross-section. The primary objective is to investigate the kinematics of the flow within and near the ...
Wave Interaction with Rectangular Trench in Density‐Stratified Fluid
Publisher: American Society of Civil Engineers
Abstract: The propagation of water waves in a direction perpendicular to the longitudinal axis of a rectangular submarine trench is studied for a density‐stratified fluid in the trench. The theoretical and experimental investigation ...
Study of Wind Waves in the Gulf Intracoastal Waterway at Aransas National Wildlife Refuge
Publisher: American Society of Civil Engineers
Abstract: This study describes a field experiment on wind waves in the Gulf Intracoastal Waterway. Wind-wave height and period were measured at the Aransas National Wildlife Refuge in Texas and compared to hindcast results generated ...
Finding the Bed Shear Stress on a Rough Bed Using the Log Law
Publisher: ASCE
Abstract: 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 ...
Flow Velocity and Pier Scour Prediction in a Compound Channel: Big Sioux River Bridge at Flandreau, South Dakota
Publisher: American Society of Civil Engineers
Abstract: The two-dimensional (2D) depth-averaged river model Finite-Element Surface-Water Modeling System (FESWMS) was used to predict flow distribution at the bend of a compound channel. The site studied was the Highway 13 bridge ...
SRICOS: Prediction of Scour Rate in Cohesive Soils at Bridge Piers
Publisher: American Society of Civil Engineers
Abstract: A new method called SRICOS is proposed to predict the scour depth
