Subsidence Properties of Holocene Sediments: S. La.
As part of a comprehensive USGS-sponsored study of processes that drive subsidence and wetland loss in south Louisiana, two continuously cored deep borings (60 m and 72 m) were acquired...

Laboratory Testing of an Artificial Reef Erosion Control Device
A physical model study has been conducted to examine the effectiveness of a concrete artificial reef in limiting offshore, storm-induced sand loss from a nourished beach. The experiment...

Physical Modeling of Barbers Point Harbor
Physical modeling is a practical tool in the design of coastal projects. A physical model of Barbers Point Harbor located on the island of Oahu, Hawaii was constructed so that different...

Coastal Morphological Modeling for the Southern North Sea
The paper gives a inventory of mathematical model concepts for coastal morphological applications, from sophisticated short-term process models based on first physical principles, via...

National Weather Service Interactive River Forecasting Using State, Parameter, and Data Modifications
Interactive flood and river flow forecasting using the National Weather Service Interactive Forecast Program (IFP) is outlined. The IFP is an extension of the National Weather Service...

Overland Flow Resistance Estimation from Small-Plot Data
The correct application of physical process models, such as the kinetic wave approximation to shallow overland flow, is dependent upon selection of appropriate values for parameters which...

Federal Levee Effects on Flood Heights Near St. Louis
A physical model of the Middle Mississippi River was used to perform quantitative analyses of Federal levee effects on flood heights. Contrary to some opinions of the general public, these...

Computational Modeling of Sedimentation Processes
The Committee on Computer modeling is a part of the task force on updating ASCE Manual 54, `Sedimentation Engineering.' The task will require a new chapter since computer...

Tidal Propagation in a Distorted Model
A largely analytical study of tidal flow in the Sacramento/San Joaquin delta system provides the basis of an investigation of physical model distortion on tidal circulation in a complicated...

Numerical Models of Phytoplankton Dynamics for Shallow Estuaries
The relationship between physical processes and phytoplankton population dynamics in coastal ocean waters is a complicated issue largely because of the shallowness of the water column,...

Regulation of Flow Downstream of Weirs
Reregulation weirs are one means adopted by the Tennessee Valley Authority (TVA) to provide continuous improved minimum flow and wetted area for aquatic life downstream if hydroprojects...

Rheometry of Natural Sediment Slurries
Recent experimental analyses of natural sediment slurries yield diverse results yet exhibit broad commonality of rheological responses under a range of conditions and shear rates. Results...

Hydraulic Modeling of High Unit Discharge Energy Dissipators
The incorporation of an efficient and economical energy dissipation device is critical with respect to the safe operation of a high unit discharge spillway. The development and design...

Model Study of Center Hill Fuse Plug Spillway
Model tests of a fuseplug spillway mounted on the fixed crest of an embankment dam were conducted to develop a satisfactory design that would fail in a orderly fashion at a prescribed...

Distorted Physical Models for Mixing Studies
The frictional resistance and mixing process affected by roughness bars are investigated. Specific combinations of the size and layout of the bars for various flow conditions are suggested...

Model Study of Rio Hondo Flood Control Channel, Los Angeles, California
The Rio Hondo Flood Control Channel located within the Los Angeles County Drainage Area (LACDA) is part of a Comprehensive flood control system which includes 20 dams, 129 debris basins,...

Effect of Fenders on Local Pier Scour
Physical model experiments were performed in the Hydraulics and Sediment Research Institute, Delta Barrage, Egypt, to determine the effect of fenders on the scour depth around circular...

Chatuge Hydroproject Aerating Infuser Physical Model Study
The Tennessee Valley Authority is investigating the feasibility of a dual purpose reregulation and aeration weir to increase the dissolved oxygen in water releases and to provide continuous...

Hydraulic Performance of a Flexible Curtain Used for Selective Withdrawal — A Physical Model and Prototype Comparison
Reclamation (U.S. Bureau of Reclamation) studied a 1:120 scale undistorted density stratified physical model to develop a lightweight flexible curtain barrier that would control the outflow...
