This report is a guide for engineers who are responsible for the design and analysis of large turbine-generator foundations. A description of the various components of turbine-generator...
Neyrtec Automatic Equipment for Irrigation Canals
The French Company ALSTHOM has developed a line of simple equipment for automatic level control and constant discharge control in canal irrigation systems. The paper includes a description...
Pipeline Types and Design Considerations
Pipelines are extensively used to upgrade irrigation delivery facilities. The advantages of a pipeline system include an improvement in water conservation and the ability to extend water...
Design of Semi-Closed Pipeline Systems
Semi-closed pipeline systems controlled by downstream activated float valves permit low pressure pipeline systems to communicate information from the outflow location back to the source...
Pump Plant Control and Automation
Pumping plants for irrigation systems can be separated into two general types: source pumps which provide water to the system and booster pumps which increase the system pressure. Typically,...
Evaluation of and Recommendations for Drop Structures in the Denver Metropolitan Area
In 1982, the Denver Urban Drainage and Flood Control District published interim guidelines for the design of sloped, loose riprap drop structures, as well as vertical wall drop structures...
Design Considerations for Hydraulic Jump Structures
The primary purpose of this paper is to define the areal distribution of large-scale pressure pulses acting on the containment structure of a hydraulic jump. The results presented are...
Stepped Spillway Design with a RCC Dam
The hydraulic model study results for the Upper Stillwater stepped spillway design are presented. The studies encompassed several spillway geometries and design unit discharges ranging...
Open Channel Flow Resistance in Horseshoe Conduits
An experimental study of open channel flow resistance in horseshoe-shaped conduits is reported. The friction factor is shown to increase approximately 20 percent in comparison to values...
Hydraulic Design Limitations for Gravity Flexible (Non-Rigid) Plastic Pipes Flowing with a Free Water Surface
Hydraulic design limitations are necessary for gravity plastic pipes when designed for use as a sanitary sewer, flowing part full with a free water surface. The limitation for pipes designed...
Rehabilitation Measures?Wanaque Reservoir System
The rehabilitation of Pompton Lake Dam and the dams of the Wanaque Reservoir System has provided the North Jersey District Water Supply Commission with a safe, dependable source of water...
Preliminary Engineering Design of an Artificial Tidal Lagoon System in Kuwait
A coastal resort project was planned for a 30 hectare site along the Arabian Gulf approximately 69 km south of Kuwait City at Dubaiyeh. The master plan, originally developed by Kuwait...
Polyhedric Surfaces
A new design for spillways is proposed. The basic idea is to substitute the traditional shape of the continuous vertical bends by polygonal plane surfaces. In this way it is possible to...
Hydraulic Design of Pamo Dam Spillway
The design of the emergency spillway for the San Diego County Water Authority's (SDCWA) proposed Pamo Dam is discussed. Pamo Dam is a 264-foot (80. 5 meter) high roller compacted...
Design of Overtopping Protection for Small Dams
Many existing small embankment dams in the United States cannot safely pass current design floods without overtopping. In the past several years, embankment overtopping protection has...
Composite Resistance to Flow With an Ice Cover
Recent data collected on several rivers in Michigan suggest, with only an ice cover present, that Manning's roughness ratio is constant at n//R equals 0. 65. If other ice...
Hydraulic Model to Improve Debris-Handling Capability of Waterford Unit 3 Intake Canal
A 1:30 scale model was used to test the effectiveness of various modifications to the Waterford Unit No. 3 intake canal. The objective of the study was to assist in the development of...
Methods for Specification and Verification of Hydraulic Design in a Turnkey Construction Contract
The project site is at the Hannibal Locks and Dam at New Martinsville, West Virginia. The existing project, a Corps of Engineers' (Corps) facility built in the 60's...
Red River Pilot Channel Design and Development
This paper presents the design parameters for two pilot channels constructed on the Red River. The factors often associated with the development of pilot channels are identified in an...
Roughness Coefficients of Large Floods
Most hydraulic calculations of flow in channels and overbank areas require an evaluation of flow resistance generally expressed as Manning's roughness coefficient, n. Literature...
