Geotechnical Properties and Landfill Disposal of FGD Sludge
Extensive test data from more than a decade of research are compiled on the geotechnical engineering properties of flue gas desulfurization (FGD) sludges with emphasis on double alkali...
Computer Aided Simulation of Fluid-Structure Interaction Problems
The papers included in this book represent state-of-the-art developments in and applications of computer aided simulation of fluid-structure interaction problems in both the terrestrial...
The NOS Experience in Real-Time Measurements of Tidal Currents
NOAA'S National Ocean Service (NOS) uses the term RADS, Remote Acoustic Doppler Sensing, for a new class of oceanographic instruments that uses acoustic backscatter to probe...
Flow Around Islands in Rupert Bay: An Investigation of the Bed Friction Effect
Aerial photographs of transverse shear flows around islands in Rupert Bay, a shallow and turbid estuary in northern Quebec, were studied for effect of bed friction. The island wake depends...
Local Scour Under Waves Oblique to Current
Local scour around a cylindrical pile subjected to waves oblique to current was experimentally studied in a laboratory flume with a wave generator. The mode of wave-current interaction...
Techniques for Measuring Flow and Sediment Parameters Near the Bed in Estuaries
The collection of accurate and meaningful field data is often the key to successful description and prediction of natural processes. The U. S. Army Engineer Waterways Experiment Station...
Effect of Atmospheric Forcing on Tide Propagation
This paper presents computations and observations indicating that nonlinear interaction with wind waves and subtidal sea level changes can change estuarine motion in the tidal frequency...
Numerical Modeling of Column Separation with Large Pressure Pulses
Liquid transients involving column separation occur in pipelines when the pressure drops to the vapor pressure of the liquid. The collapse of vapor cavities may result in short duration...
Turbulent Transverse Shear Flows in Shallow Waters
Shallow turbulent mixing layers, generated downstream of a splitter plate between a fast and a slow open-channel flows of shallow water depth, were investigated experimentally for vertical...
Gradation and Layer Thickness Effects on Riprap
Since riprap has become a costly and in some areas, scarce commodity, proper design maximizing the level of protection with a minimum rock size and layer thickness is an important goal....
Time Averaged Estuarine Mass Transport Equations
A methodology for deriving time averaged mass transport equations for estuaries having weakly nonlinear long wave dynamics is presented. A 2D in-plane advection-dispersion equation for...
Design of Overtopping Protection for Small Dams
Many existing small embankment dams in the United States cannot safely pass current design floods without overtopping. In the past several years, embankment overtopping protection has...
Advanced Concept for Generation of Waves in Hydraulic Models
This paper describes a new wavemaker for the generation of naturally occurring waves in physical models of coastal areas. Recent research incorporating directional aspects of monochromatic,...
Mechanics of Embankment Erosion During Overflow
Thousands of dams built in the United States have a potential to be overtopped by flood flows. It is necessary to understand the mechanics of embankment erosion in order to evaluate the...
Embankment Overtopping?Case Histories
Because many existing dams are subject to overtopping, there is a need to understand embankment behavior during an overtopping event. Understanding of this behavior will allow evaluation...
Predicting and Minimizing Embankment Damage Due to Flood Overtopping
Under a contract with the Federal Highway Administration and Bureau of Reclamation, Simons, Li & Associates, Inc. (SLA) is conducting an overtopping damage study to evaluate various...
Limitations of Saint Venant Equations to Model Flood Waves
The subject of this paper is in direct contrast to all previously known research efforts. Previous effort has focused on simplified forms of Saint Venant using approximate routing models...
River Wave Response to the Friction-Inertia Balance
The changing character of the solution of the Saint-Venant equations for river flow problems with the dimensionless parameter F//I reflects a changing balance between friction and inertia....
Refined Modeling to Estimate Sediment Discharge
Numerical solution of the two-dimensional turbulent flow over a train of identical dunes is obtained with the Algebraic Stress Model for closure. The effective tractive force acting on...
Infiltration as a Dependent Variable in Modeling Furrow Irrigation
Most surface irrigation models assume that infiltration is independent of surface flow hydraulics. However, wetted perimeter has been shown to significantly affect infiltration in furrows....
