Critical Flow Through Bridge Piers
A physical model study was performed at California State University, Long Beach to investigate the location of critical depth within bridge piers in supercritical lined channels. This...
Intake Wheel Gates Sealing Arrangements
This article discusses the sealing arrangements for intake wheel gates. Advantages and disadvantages if upstream and downstream sealing arrangements including thier effects on the performance...
Hydraulic Modeling of Flow Control Gates
Flow control gates are subject to complex hydrodymanic loadings, which may in many cases only be predicted through investigation on a physical hydraulic model. Scaling of gate models,...
Ring Gate as Turbine Emergency Shut-Down Device
The ring gate, intially used as a regulating device in the early stage of the design of hydraulic turbines, has grown to a reliable emergency shut-down device. Incorporated in the hydraulic...
Minimizing Erosion Damage to Embankments, Spillways, and Channels With Articulated Concrete Block Revetment Systems
The results of a multi-year applied research and testing program, focusing on the hydraulic performance of various types of erosion control products and revetment systems in steep-slope...
Chute Design Using Concrete Building Blocks
Chutes constructed using concrete building blocks for erosion control on ephemeral streams have performed successfully. The chutes consist of a layer of blocks placed on a geotextile over...
Delineation of Ordinary High Water
'Ordinary high water' is used in a court of law to delineate the extent of land ownership of adjacent riparian owners on navigable rivers. The most appropriate...
Decoverly Lake?Functional Hydraulics & Aesthetics
The Decoverly Office Park is located in Rockville, MD. In 1984, engineering design on the seven office building park and pond was begun by the consulting engineers. From the beginning,...
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...
The Piedra del Aguila Project Large Radial Gates
Piedra del Aguila Hydroelectric Project is on the Limay River in Argentina. It has a capacity of 1424 MW with annual energy of 5500 GWH. This is an overflow dam, with intake gates, penstocks...
Diversion Closure Gate Schemes Used on B.C. Hydro Dams
Over the last 25 years B.C. Hydro has designed, built and has operated a number of large dams and continues to do so. This paper describes the design, erection and operating experiences...
Slurry Removal From a 2-D Fluidized Region
A two-dimensional fluidization experiment is performed on fine sand with a 5.08 cm diameter source pipe with horizontally opposed orifices, 0.317 cm in diameter, spaced 5.08 cm. Slurry...
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....
Experimental Research and Parameters Optimization of a Prototype OWC Wave Power Device
The paper presents the experimental research and parameters optimization of a prototype oscillating water column (OWC) wave power device being built in China by Guangzhou Institute of...
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...
A Semi-Empirical Model for an OC-OTEC Spout Flash Evaporator
A phenomenological model for the thermal-hydraulics of a spout flash evaporator is presented in this paper. The model considers the two-phase flow behavior both in the spout and in the...
Stresses in Concrete Armor Units
This book is derived from a Seminar at the Waterways Experiment Station, Coastal Engineering Research Center, Vicksburg, Mississippi held on November 7-8, 1989. It presents a state-of-the-art...
50th Anniversary of the Hydraulic Division 1938-1988
