Three-Dimensional Numerical Modeling for Transport Studies
Modeling three-dimensional transport of salinity and sediments in estuarine flows requires that hydrodynamics be accurately modeled with sufficient precision to describe the advection...

Mixing Character and Meandering Mechanism of a Plane Jet Bounded in a Shallow Water Layer
A plane jet in a shallow water layer is characterized by the jet width b1/2 much larger than the water depth h at large downstream distances x/h...

Shifts in Solute Transport Direction Induced by Transient Flow
Traditionally, solute transport projections have focussed on the long-term, steady state conditions expected to prevail in a groundwater system. However, transient effects may often dominate...

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...

A Diffusion Hydrodynamic Model of a Shallow Estuary: Verification
Many of the hydrodynamic models used for estuary tidal flows and storm surges are based on two two-dimensional hydrodynamic equations which are obtained form the full three-dimensional...

Structure of Coastal Upwelling on a Sloping Bottom
A large eddy simulation of coastal upwelling on a sloping bottom is carried out. The structure of the upwelling consists of a persistent primary front, a temporary secondary front which...

The Courant Number and Unsteady Flow Computation
The Courant number C, the key to unsteady flow computation, is a ratio of physical wave velocity, ?, to computational signal-transmission velocity, ?, i.e., C = ?/?. In this way, it uniquely...

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...

A Culvert Analysis Program for Indirect Measurement of Discharge
A program based on the U.S. Geological Survey (USGS) methods for indirectly computing peak discharges through culverts allows users to employ input data formats used by the water surface...

Analysis of Local Scour at Bridge Piers
Many studies have been performed on the cause and effects of local scour at bridge piers, and various prediction equations have been generated based on these studies. The general approach...

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...

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...

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...

Pipeline Leak Detection Based on Mass Balance
Current technologies in Supervisory Control and Data Acquisition (SCADA) systems enable pipeline leak detection to be carried out in real time by software-based methods. This paper discusses...

Relocating a 54-Inch Diameter Force Main without Interrupting Wastewater Flow
The City of Tampa, Florida, was faced with the challenge of relocating three segments of an old 1372 mm (54-in.) diameter reinforced concrete pipe force main, totaling nearly a mile in...

Use of Surface Treatments on Airport Pavements
Asphalt is generally used as the surfacing for flexible airport pavements with airline passenger jet aircraft. In Australia and its neighbouring territories, surface treatments (seals)...

Hydraulic Engineering
This proceedings, Hydraulic Engineering, contains papers presented at the 1993 National Conference on Hydraulic Engineering held in San Francisco,...

Permeability Determination for Unsaturated Soils
A reliable approach for the determination of the soil hydraulic conductivity function relies on the parameter estimation solution approach in which heterogeneous state of saturation within...

Transit Times Through Compacted Clay Liners
Transit time, or time taken by waste liquid to move through the thickness of the liner, is a short-term performance parameter which can be used to determine the necessary liner thickness....
