Computational Open-Channel Hydraulics for Movable-Bed Problems
As a major branch of computational hydraulics, notable advances have been made in numerical modeling of unsteady open-channel flow since the beginning of the computer age. According to...

A Generalized Diffusion Wave Flood Routing Model
A generalized diffusion wave model for flood routing is presented. The model can incorporate detailed data on natural cross sections and river bed geometry. An accurate numerical method...

Development of a Computer Aided Decision Process for Channel Rehabilitation and Watershed Enhancement Techniques
To assist the engineer in planning and design of channel stabilization measures, an expert system (CADWET) was developed using a commercially available expert system shell program. The...

Use of Linear Programming for Hydraulics Problems
Water is becoming a more and more precious commodity worldwide with each passing day. At the same time, the optimum and most productive solutions to water control and utilization are becoming...

Equivalence Between Regular and Irregular Waves in Movable-Bed Models
Laboratory experiments were conducted to evaluate various irregular wave parameters to determine which provides the best match for the regular wave parameter used to develop design guidance....

Pump Selection Program and a Better User Interface
Numerous highly innovative computer solutions to engineering problems are of little use to the practicing engineer because these programs are not supported by adequate user interface....

Compact Pump Sump Design
This paper details the design criteria chosen to construct a pump sump within several on-site constrictions. The physical size restrictions of the site necessitated the construction of...

Hydraulic Analysis for the Shot Tower Subway Station Beneath the Jones Falls
The objective of the hydraulic analysis is the formulation of a strategy to safely accommodate the construction of the Shot Tower Metro Station beneath the existing Jones Falls. The hydraulic...

Comparison of Flush and Chamber Mounted Dynamic Pressure Transducer
Modeling of hydraulic structures often includes the measurement of dynamic pressure fluctuations. The accuracy of the pressure measurements depends upon the geometry of the tap. Flush...

Coronarization of the Autonomous Water pump
The conventional hydraulic pressure multiplier has been successfully used by Belgian technician Robert Houman (1986) to provide a dependable source of water supply to the NATO-base at...

Redondo Beach King Harbor Model Studies, California
Redondo Beach King Harbor frequently experiences damage when large winter waves occur in conjunction with high water levels. Damages consist of revetment failure, land erosion, flooding,...

Physical Model Study of Navigation Conditions
This paper describes a physical model study performed to assess the impact of increased flows from a redeveloped hydroelectric generating station on the ability of pleasure boats to navigate...

Low-Head Drop Structure Hazards: Modeling of an Abrupt Drop Boat Chute
Low-head drop structures are dangerous for navigational and recreational boating in rivers. In an effort to reduce drowning hazards at low-head river drop structures, a boat chute bypass,...

Hydraulic Modeling of Boating Hazards and Sedimentation?Union Avenue Dam, Denver Colorado
Hydraulic jump type energy dissipators are a hazard to recreational boaters. Many white water boaters have been trapped in 'reverse roller' hydraulic jumps. Numerous...

Characteristics of Flow Pressure Pulsation and Similitude Law of Model
As described in this paper, the characteristics of flow pressure pulsation and similitude law of model are derived from experiments on some prototype dam and serial scales models....

Numerical Modeling of Irregular Hydraulic Jumps
In its simplest form a hydraulic jump characterized by an abrupt increase in the water surface elevation from a depth less than the critical depth, D_c,...

Solving Turbulent Flows with Finite Elements
A finite element computer code using the q - r turbulence model is applied to turbulent flow under a sluice gate. The addition and slow removal of artificial diffusion enhances convergence....

Effect of Barrier Beach Breaching on Harbor Dynamics and Storm Surges
This paper presents a summary of the flood insurance study, commissioned by the Federal Emergency Management Agency, to determine the 100-year flood elevation for Chatham, a seacoast town...

Effects of Tide on Variation of Beach Profile
Effects of tide on variation of beach profile are examined experimentally. It is clarified that tidal effect appears differently when it acts on beach of different profiles. Namely, in...

Cumulative Impacts Analysis on a Midwest Fluvial System
The US Army Corps of Engineers recently completed an analysis of the cumulative impacts of erosion control structures on the Platte River in Nebraska. This was done in response to concerns...
