Three-Dimensional Modelling of Recirculation Behind a Groyne
Extensive investigation on the three-dimensional flow patterns behind a groyne have been carried out in a small-scale experiment. A three-dimensional hydrodynamic numerical model is verified...

Validation and Recent Enhancement of a Three-Dimensional Curvilinear-Grid Finite-Difference Model for Estuarine, Coastal and Lake Circulation: CH3D
This paper describes the validation and recent enchancement of a three-dimensional curvilinear-grid hydrodynamic model: CH3D. The model employs finite-differences techniques and allows...

River Engineering and Environmental Resources
The federal government and the Corps of Engineers (CE) are committed to preserving and enhancing environmental quality. Research and development support for this commitment in the realm...

Impact of Agricultural Levees on Flood Elevations
Agricultural levees are used in many low-lying areas to protect farmlands from floods. The levees are often constructed, maintained, and improved on an ad hoc basis by farmers or with...

Modelling of Stages of Nile River as a Tool for a Better Water Resources Management
As far as Egypt is concerned, the Nile is not just a river, it is rather the pulsing nerve of life. Consequently, it was essential to maintain detailed information about its levels and...

Overview of Mathematical Models?River Nile/High Aswan Dam
This paper has been directed towards the presentation of seven reliable planning tools (mathematical models) that can be used for the investigation of the planning options facing policy...

Basin-Wide Stormwater Management in Pennsylvania?A Case Study of Hydrologic Performance Standards
Performance standards in the form of 'release rates' are developed using hydrologic computer models. This basin-wide approach to stormwater management considers...

Model Tests for Design of Vibration-Free Gates
Experimental results are presented of hydraulic forces acting on an underflow gate. Underflow gate is a socalled bluff body and a review of the mechanism of vibration caused by separation...

Spillway Gates for the El Naranjero Dam in Spain
In June 1986 Zwag Zschokke Wartmann Ltd received the order from Hidroelectrica Espanola S.A. in Madrid, Spain for the design and model testing of 5 radial gates on the 'El...

Next-Generation Local Scale Hydromet Forecasting System
Research and development work is being conducted for the National Weather Service on a new-generation flash flood monitoring and forecasting computer workstation. The workstation represents...

Horizontal Density-Gradient Effects on Simulation of Flow and Transport in the Potomac Estuary
A two-dimensional, depth-integrated, hydrodynamic/transport model of the Potomac Estuary between Indian Head and Morgantown, Md., has been extended to include treatment of baroclinic forcing...

Dispersion of Tracers Along the Coast of Singapore
The primary objective of the present study is to model numerically the dispersion of a cloud of fine radioactive tracers along the east coast of Singapore. The results of a hydrodynamic...

Experiences With a Supercomputer
The advent of ever faster and ever larger computers is opening new areas of scientific study. Within this computational revolution, however, are real people trying to cope with the vagaries...

Three-Dimensional Model of a Stratified Estuary?St. Andrew Bay System, Florida
A three-dimensional modal is applied to a northwest Florida estuary to provide the initial insights into the circulation and flushing patterns of the system. The model, developed by the...

Long-Term Numerical Simulation of Three-Dimensional Hydrodynamics of Chesapeake Bay
A time-varying 3D numerical model of Chesapeake Bay has been developed to provide flow fields to a 3D water quality model of the bay. The water surface, 3D velocity field, salinity, and...

Model Study of the Guadalupe River Bypass Culvert
A hydraulic model investigation of proposed channel improvements for the Guadalupe River Channel was conducted at the US Army Engineer Waterways Experiment Station in Vicksburg, Mississippi....

Microcomputer Applications in Transportation III
This proceedings consists of papers presented at the International Conference on Microcomputers in Transportation which was held on June 21-23, 1989 in San Francisco, California. They...

Study on Pneumatic Wave Power Conversion System with the Water Valve Rectifier
We experimentally and theoretically studied the energy conversion characteristics on a new type of wave power conversion system with water valves. The hydraulic model experiment was performed...

Research and Development of Wave Pump
A new device, 'Wave Pump' is introduced here. The authors present the mechanism of the system, the analytical method for discharge rate, the hydraulic model test...

Tidal Power Plants - The Source of Ecologically Clean Energy
This paper outlines the development of tidal energy within the Soviet Union (U.S.S.R.). It describes several working and proposed tidal power plants developed in the U.S.S.R. with a discussion...
