Three-Dimensional Variable Resolution Hydrodynamic and Transport Modeling of the Chesapeake Bay System
This paper describes a domain decomposition methodology used in the application of the three-dimensional environmental fluid dynamics code, EFDC, to model hydrodynamics and transport in...
Modeled Hydraulic and Salt Transport Patterns in the Sacramento-San Joaquin Delta
Modeled hydraulic and salt transport patterns in the Sacramento-San Joaquin Delta have been summarized as the basis for detailed environmental assessment of proposed water management projects...
River Engineering Flows and Some Related Structures (State of the Art)
The first part of the paper deals with a simplified overall review of water flows. Laminar versus turbulent, visualization of flow with unsteady 3-D manner and some typical hydraulic structures...
Vortex Spillway: Test Study on a Hydraulic Model
The paper deals with an experimental study on a model of the forced vortex of Eur hanging reservoir realized by ACEA (Rome). Some vortex characteristics are investigated and, in particularly,...
Bridge Scour Evaluations in Washington State
Eighteen existing bridges were investigated for Washington State DOT as part of the FHWA National Scour Evaluation Program. Investigations included review of file information, site inspection,...
Variability in Solutions of Constrained Optimization Problems: Ocean Outfall Design Case
Uncertainty in optimization model resulting from parameter uncertainty has not been well studied in the hydraulics and water resources areas. To make valid decisions, knowledge of the...
Hydraulic and Water Quality Reliability and Resiliency for Water Distribution Systems Under Random Demands
This paper develops a preliminary method to evaluate the reliability and resiliency of water distribution systems under random spatial and temporal demand patterns, including random fire...
Simulation of 3D Free Surface Flows in Hydraulic Structure with Submerged Flow Passages
This paper presents primarily the results of an application of the newly refined computational simulation model to study three-dimensional flows in a lock and dam system, which has submerged...
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...
Flow Diversion in a Steep, Coarse-Bed Stream
A case study is presented of the hydraulic design of a diversion structure in a high velocity, coarse bed streamcourse. Mill Creek, a tributary to the Upper Jordan River in the southern...
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...
Self-Cleaning Wet Wells: Definition and Design
Design guidelines for self-cleaning wet wells with variable speed pumps are given and the progress of research at Montana State University and ENSR Consulting and Engineering concerning...
Flow Study of In-Service Sanitary Sewers Rehabilitated with Insitupipe
In an effort to define the flow characteristics of sanitary sewer segments rehabilitated with Insituform under normal in-service conditions, Insituform of North America, Inc. (currently...
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...
Liquefaction Potential of Western Puerto Rico
The historical seismic record, paleoseismic evidence, high population density, time expired since the last major earthquake, and the presence of liquefiable sands and soft clays combine...
The Proof is in the Pavement
A technique known as statistical quality assurance (SQA) lets DOTs quantify pavement quality by setting statistical guidelines for the work they will accept. SQA is a distinct departure...
RCC: Rehab Results
Thirty dams have been modified with roller compacted concrete in order to provide additional spillway capacity and for safe overtopping of embankment dams. In the national dam safety inspection...
