Critical Features of Custom Design Hydro Gates
Large hydro gates are custom designed to suit each particular installation. To prevent overlooking a feature that could lead to future problems, a check list of the numerous features should...
Crest Gates Design for Upper Mechanicville
This paper describes the design of flap-type spillway crest gates for the Upper Mechanicville Project, located on the Hudson River near Mechanicville, New York. These gates are being provided...
Oil Hydraulic Design for Turbine Control
The paper addresses three areas of Oil Hydraulic Design for Francis and Kaplan Turbines: smart accumulator condition sensors, high flow servo logic, and high pressures Wicket Gate cylinder...
Civil Engineering Guidelines for Planning and Designing Hydroelectric Developments
Movable Dam?Gate Selection Procedure
Very few new dams are now being considered, particularly for waterpower and even more specifically for low head waterpower in the lower reaches of major rivers. The City of Harrisburg,...
Development of Turbine Intake Downstream Migrant Diversion Screen
Prior to the spring of 1986 Public Utility District No. 2 of Grant County had developed a passive turbine intake screen design. A prototype of this design was placed in the emergency gate...
Designing a Modern Small-Scale Hydroelectric Plant
STS Consultants, Ltd. (STS) and Skidmore, Owings & Merrill (SOM) successfully teamed on four hydropower sites in Michigan during the 1980's. Three of the four sites...
A Model of Flow in Regulated Open Channel Networks
A model (NETWORK) is presented for the simulation of unsteady flow in regulated open channel networks. The operation of hydraulic structures, such as gates and weirs, are simulated as...
Simulation and Video Animation of Canal Flushing Created by a Tide Gate
A tide-gate algorithm was added to a one-dimensional unsteady flow model that was calibrated, verified, and used to determine the locations of as many as five tide gates that would maximize...
Sediment Flushing Experiences at Cherry Creek Dam
An overview of the U.S. Army Corps of Engineers, Omaha District's experiences in sediment flushing operations at Cherry Creek Reservoir near Denver, Colorado is presented....
Artificial Recharge of the Heretaunga Plains Aquifer Hawke's Bay, New Zealand
The Heretaunga Plains groundwater system in the Hawke's Bay region of New Zealand, is naturally recharged from the nearby Ngaruroro River at the approximate rate of 5.5m3/sec....
Controlled-leak Methods for Water Level Control
The controlled-leak methods are a group of similar techniques for controlling upstream water levels, downstream water levels, or offtake canal discharges. They require no electrical power...
Canal Automation Using the Electronic Filter Level Offset (EL-FLO) Method
Beginning in 1969, the Bureau of Reclamation began testing and refining an electronic filter level offset (EL-FLO) control system for canal automation. The control system uses a proportional...
Philosophy and Implementation of Gate Stroking
The purpose of this paper is to examine one control method - gate stroking - the philosophy which would lead to its selection and an example of its implementation. Gate stroking provides...
Instrumentation for Automated Irrigation Systems
Remote site instrumentation sensors are vital components in automated irrigation systems, enabling measurement of water levels, flows and gate positions. It is desirable to select sensors...
Dam Safety Improvements for Tolt River Dam
Studies were performed to identify measures to improve the safety of the project under earthquake and extreme flood conditions while permitting the owner to store additional water under...
Estimation of Navigation-Dam Discharge in Illinois
Techniques were used to estimate discharge for the Brandon Road Dam on the Des Plaines River and the Dresden Island, Marseilles, and Starved Rock Dams on the Illinois River in northern...
Hydraulics of Enlarging Cannonsville Reservoir
This paper describes the hydraulic studies performed for enlarging the Cannonsville Reservoir with a gate system which could raise the normal storage level without having an adverse effect...
A Real-Time Flood Management Model for River-Reservoir Systems
A flood forecasting model has been developed for the Lower Colorado River Authority that can be used in a real-time framework to make decisions on reservoir operations during flooding....
Maximum-Slew-Rate Nonlinear Control for Improved Transient Response in Hydrogenerators
This paper considers a linearized model for fixed blade turbines. This paper demonstrates that constant gate speed bang-bang control holds potential advantages over current control techniques....
