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...

Operational and Structural Optimisation of Hydraulic Structures for Light Liquid Removal
The removal efficiency of light liquid separation schemes is determined by the hydraulic inflow conditions, the inflow fluid properties and the separator hydraulics. The relating set of...

Observations of Artificial Destratification
Artificial destratification using bubble plumes is one means whereby low dissolved oxygen in the hypolimnion of lakes and reservoirs may be averted. Temperature and DO were measured at...

Drag Characteristics of Coarse Sediment in Clay Suspensions
Drag characteristics of spherical particles in clay suspensions, such as coarse sediment in hyperconcentrated flows, has been analyzed by using a limited data available in the literature....

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...

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,...

Estimating Bridge Scour in New York from Historical U.S. Geological Survey Streamflow Measurements
Historical streamflow measurements by the U.S. Geological Survey an bridge-inspection reports by the New York State Department of Transportation are being used to estimate scour at 31...

Relation of Local Scour to Hydraulic Properties at Selected Bridges in New York
Hydraulic properties, bridge geometry, and basin characteristics at 31 bridges in New York are being investigated to identify factors that affect local scour. Streambed elevations measured...

Scour Inspection Using Ground Penetrating Radar
This paper examines the capabilities of Ground Penetrating Radar (GPR) for river bed scour inspection based on a study carried out by Clarkson University, Potsdam, New York in association...

Time-Dependent Landslide Probability Mapping
Case studies where time of failure is known for rainfall-triggered debris flows can be used to estimate the parameters of a hazard model in which the probability of failure is a function...

Evaluation of Hydraulic Structure Reliability Considering Uncertainties in Hydrologic Models
Uncertainties in a hydrologic model give rise to uncertainty in model outputs which, in turn, can be used for reliability-based design and /or evaluation of hydraulic structures. This...

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...

Thermal Shielding in Continuous Span Composite Slabs
The increasing popularity in Europe of composite slabs with cold-formed steel decking has underscored the need to improve calculation rules for the fire resistance. Existing rules have...

A Simple Finnish Method for the Structural Fire Design of Composite Structures
The structural fire design of composite structures in Finland has previously been based on furnace tests, which are expensive and take too much time to arrange. With the increasing prominence...

Chemical Resistance of Thermosetting Resins Used for Cured-in-Place Pipe
This paper summarizes the chemistry, short term physical properties, and long term chemical resistance for representative epoxy vinyl ester, epoxy, and polyester resins that are currently...

Equipment Systems for the Commercial Production of Modified Asphalt
A considerable amount of research has been centered on various asphalt modifiers and their effect on rheological properties. As the paving industry is now focusing on high performance...

Application Cases of Slurry Seal in Japan
In Japan, slurry seal began to be used for repairing asphalt pavements at around 1963, mostly for repairs of prefectural and municipal roads. In recent years, however, it has rarely been...
