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...

Comparison of Some River Discharge Calculation Methods
To measure the discharge of a river, it is necessary to develop a stage-discharge curve based on water velocity at various cross sections of the river. This is the method which is used...

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...

Modification of Meander Pattern Using Wing Dams
A sharp river bend and a highway bridge together create potentially hazardous conditions for all down-bound barge tows on the Mississippi River at Lansing, Iowa. The tendency of the river...

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...

Hydrologic Design Criteria for Dams with Equal Reliability
Appropriateness of design criteria which require using the same Antecedent Moisture Condition (AMC) throughout Kansas for sizing dams and emergency spillways was examined. AMC values which...

Effective Precipitation in Irrigation Design and Management
Effective precipitation is important in irrigation system design and operation. Numerous methods for estimating effective precipitation have been proposed in the past, including direct...

Crop-Water Production Functions and System Design
A Task Committee to evaluate application of crop-water production functions to irrigation system design and management was established by the ASCE Irrigation Water Requirements Committee...

CWSI and Stomatal Resistance of Cotton and Soybeans
A new instrument, Scheduler(TRADEMARK), has been developed to measure the onset and duration of plant water stress. This device consists of a sensor package (containing an infrared thermometer,...
