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...
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 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...

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....
A Design Manual for Coastal Fluidization Systems
This paper summarizes a recently completed design manual on fluidization systems to manage sand in the coastal environment for sand bypassing at inlets and harbor mouths and for creating...
Should the U.S. Accept the Concept of Navigable Depth?
Navigable depth is defined as the maximum depth of water from the chart datum that is safe to accept as the bed of the channel, such that damage does not occur to a ship's hull and maneuverability...
Wave Interaction with Fluid Mud in Rectangular Trench
Wave interaction with fluid mud in a rectangular trench is studied theoretically based on small-amplitude wave theory. The problem was formulated using the Voigt model for an viscoelastic...
Aspects of Parallel Processing in Reservoir Simulation
Vectorization techniques have proved to be extremely effective for large-scale reservoir simulations. Parallel capabilities hold even greater potential for these enormous problems. Domain...
Nonlinear Behavior of Thin Slender Free Surface Non-Newtonian Elliptical Rings
This paper analyzes the nonlinear motion of a slender concentric thin elliptical ring of an incompressible, non-Newtonian fluid. This study includes the physical effects of surface tension,...
Computerized Tomographic Analysis of Fluid Flow in Fractured Tuff
The purpose of this summary is to demonstrate the usefulness of X-ray computerized tomography to observe fluid flow down a fracture and rock matrix inhibition in a sample of Bandelier...
Water Wave Generated by a Porous Wavemaker
