Effect of Nile River Flow on Performance of Shoubrah Power Plant Cooling System
Shoubrah El-Khimah Power Plant was built in 1982. Its peak capacity is 1200 MW, generated by four units, three of them having one cooling water intake. The cooling water pumps suffer from...

Bed Forms of Nile River
In this paper, the observed bed forms for six different reaches of the Nile River in Egypt are described. The purpose of the study is to inquire whether or not the different available...

Application of Stable Channel Design Method
Systematic stable channel design methods are currently being developed by the US Army Engineer Waterways Experiment Station for use in the planning stages of local flood control projects....

Bed Load Roughness in Supercritical Flow
A supercritical concrete channel is proposed for Mission Creek located in Santa Barbara County, California. The proposed channel may transport gravels and cobbles as bed load during large...

Operational Procedures for Estimating Bottom Exchange Rates
After briefly reviewing the terminology of the various bottom and water column exchange fluxes, the body of this paper summarizes five possible procedures for establishing operational...

Standardization of Culvert Flow Computations
Culvert flow computations are generally computed by the Federal Highway Administration's (FHWA) nemographs or its HY8 computer program, the U.S. Army Corps of Engineers'...

Stepped Spillway Design for Flow Over Embankments
Many embankment dams have been identified as unable to pass their design flows without failure due to overtopping. The U.S. Bureau of Reclamation (Reclamation) is currently at the forefront...

Three-Dimensional Velocity Distribution at Open-Channel Diversions
A study is underway to develop an improved understanding of the 3-D flow pattern at 90? diversions. The main goal is to explain, via the velocity distribution, the behavior of sediment...

Fluidization Pipe Hole Spacing
Two-dimensional fluidization experiments are performed on fine (d50 = 0.15 mm) and medium coarse (d50 = 0.45...

A Review of Sediment-Water Column Process Modeling and Future Applications in Waste Load Allocation
The capabilities of empirical modeling techniques are discussed and three promising mechanistic models to simulate sediment-water interactions are reviewed with respect to their possible...

Submerged Vane Projects for Bank Stabilization and Sedimentation Management
Submerged vanes are small flow training devices placed in a stream to eliminate or create secondary currents to direct sediment in a controlled fashion. In recent years submerged vanes...

Modeling and Field Experiments for Tracer Gas Tests
Numerical modeling and field experiments were used to extend the tracer gas technique for determining surface gas transfer rates to shallow bays. Two-dimensional modeling was used to investigate...

Field Verification of Diffuser Performance
Effluent diffusers are used to gain relief from end-of-pipe acute toxicity criteria in NPDES water quality-based discharge permitting. Regulatory agencies require that the dilution provided...

Finite Element Modeling of Flow in Wetlands
Requirements for developing a mathematical model of unsteady flow in wetlands are suggested. An equivalent continuum approximation is appropriate to avoid problems of describing the turbulence...

TABS-2 Application to Kawainui Marsh Flood Control
The TABS-2 mathematical modeling system was used to evaluate the effectiveness of alternatives designed to eliminate flooding problems in the Kawainui Marsh located in Kailua on the east...

Tidal Mass Exchange Between a Submersed Aquatic Vegetation Bed and the Main Channel of the Potomac River
Tidal mass exchange between a submersed aquatic vegetation (SAV) bed and the main channel of the Potomac River was investigated. Water levels were recorded at 5 minute intervals from August...

The Role of Computational Fluid Dynamics in Hydroturbine Analysis
Prospects of developing comprehensive methods of computational fluid dynamics for the analysis and design of new generation of hydroturbines are considered. Unique requirements for this...

Numerical Modeling of Air/Water Mixtures for Internal Flows
The Tennessee Valley Authority (TVA) currently is working with several organizations to develop design tools for the aerating hydroturbine. Part of this effort includes the investigation...

One Dimensional Finite Element Model for Spillway Flow
This paper summarizes the development and preliminary testing of a one dimensional numerical model termed 'CURVE1D.' The model is nonhydrostatic, including bed...

Flood Control Design for Development on Alluvial Fans
Hydrology, debris production, sediment transport and hydraulic studies were conducted to provide flood control for a development within an alluvial fan floodplain. Innovative techniques...
