Water Conveyance Facilities on the Central Arizona Project

Hazard Evaluation of Mokelumne Aqueducts

Central Arizona Project: Operations Model
An optimization model is developed to determine operating policies for the Granite Reef Aqueduct of the Central Arizona Project CAP with the objective of minimizing the on-peak hour pumping...

Stresses in Rigid Pipe
In 1930 Marston theorized that earth pressures on a rigid pipe would assume bulb-shaped patterns. The theory was confirmed in experiments carried out at Iowa Engineering Experiment Station....

Direct Solution to Problems of Open Channel Transitions
Existing methods of solving problems of open channel transitions involve trials-and-error solution of higher degree equations and no direct solutions are available in technical literature....

1842: Old Croton Aqueduct Brings Water, Rescues Manhattan From Fire, Disease
From 1774 to 1835 Manhattan experienced tremendous growth but needed better water supply to protect public health and to fight fires. Several proposals for providing water were forwarded...

1842: Old Croton Aqueduct Brings Water, Rescues Manhattan From Fire, Disease
From 1774 to 1835 Manhattan experienced tremendous growth but needed better water supply to protect public health and to fight fires. Several proposals for providing water were forwarded...

Aqueduct Optimization with Intermediate Storage
A new method has been presented for determining optimum aqueduct capacity with intermediate storage along the aqueduct. The method maximizes the net benefits and determines the optimum...

Optimization of Design Capacity of an Aqueduct
A methodology to determine aqueduct design capacity under varying demand conditions has been developed. Two models of increasing complexity have been presented. In the first model the...

Flow Control and Transients in the California Aqueduct
From initial operation of the California Aqueduct of the California State Water Project in 1967 to the present, the method of gate operation for flow control has been modified to keep...

Planning the Tehachapi Crossing
Planning the California Aqueduct crossing of the Tehachapi Mountains in California north of Los Angeles involved 10 yrs of intensive research and study in the United States and Europe...

Repair of Seismic Damage to Aboveground Pipelines
The San Fernando Earthquake of February 9, 1971, caused severe damage to aboveground steel pipe sections of the two aqueducts serving Los Angeles. This damage resulted from different ground...

The Undersea Aqueduct—A New Concept in Transportation
Growing imbalances between available water sources and growth areas requiring large volumes of high quality water lend a new urgency to the need for exploring alternatives for transporting...

Effects of Mechanical Cleaning Operations on Flow in Large Conduits
By following a systematic cleaning and maintenance program in recent years, the Colorado River Aqueduct has been kept in condition to deliver substantially greater flows of water to the...

Operation and Maintenance of Colorado River Aqueduct
The 242-mile Colorado River Aqueduct of The Metropolitan Water District of Southern California requires a highly efficient maintenance program to permit it to exceed its original design...

Aqueducts for Least Cost Conveyance of Water
Models of the cross section of a tunnel, a pipeline and a canal are designed showing the relative sizes of all dimensions. These relative sizes are all related to some one important dimension....

Wastewater Reuse—A Supplemental Supply
Historically, Los Angeles County has learned to quench its thirst from many sources. Completion of the California Water Project in 1971-72 and the second barrel of the Owen River Aqueduct...

Aqueduct Route Optimization by Dynamic Programming
The structure of a regional irrigation project supplying water to a number of villages scattered over a relatively flat area is modeled by a series of straight lines across the contours,...

Design of California Aqueduct
Design of the California Aqueduct Project by the California Department of Water Resources considered scheme of operation as an integral component of the physical design of the system....
