Expert Analysis in Regulated Irrigation Canal Modelling
Application of riverine unsteady-flow numerical modelling techniques to problems of flow regulation in irrigation canals invokes the need for careful treatment of some situations not commonly...
Lake Michigan Diversion at Chicago
Water has been diverted from Lake Michigan to the Mississippi River basin beginning with the construction of the Illinois and Michigan Canal in 1848 to serve navigation needs. During the...
Mixing of Thermal Discharges at Low Froude Numbers
A study was performed to develop an optimum configuration for the discharge canal of a cooling lake. The objective was to minimize the initial mixing at the end of the discharge canal,...
Performance of Submerged Vanes for Control of Sediment in an Irrigation Canal
Removal of accumulated sediments from irrigation canals is necessary in order to maintain canal capacity. Removal of these sediments may be enhanced by directing and concentrating sediments...
Thermo-Hydrodynamic Modelling of the Chicago Sanitary and Ship Canal
A one-dimensional numerical model of the Chicago Sanitary and Ship Canal and Lower Des Plaines River has been developed as a tool for assessment of the waterway's thermal response to actual...
Applying Sustainable Development
Experts hoping to lessen the harsh effects of development on Earth's ecosystem have turned to the concept of sustainable development. Engineers are finding old ways to put...
Tidal Pumping Effects in Coastal Loop Canals
During the last half century the world's coastal zones have been rapidly developed and urbanized, especially in the industrialized world. The coastline of the State of Florida is a typical...
Research on the Buffer Effect of Canals
In Japan, canals for transport have been developed on the coast of urban areas. Recently, it has become evident that those areas are under chaotic conditions due to the decline of the...
Management of Supply Canals in a Rotation Irrigation System
Management of the water supply canals in a rotation irrigation system can affect the uniformity of water delivery to farms. Different management procedures are needed, depending on the...
Long Range Planning for System Rehabilitation and Improvement
The Turlock Irrigation District, located in the Central Valley of California, supplies irrigation water to 150,000 acres and electricity to over 60,000 customers. The District's irrigation...
Predicting Water Quality at Municipal Water Intakes?Part I: Application to the Contra Costa Canal Intake
The factors affecting water quality at a municipal surface water intake in the Sacramento-San Joaquin Delta are discussed. A model is developed that successfully predicts the seawater...
Egypt's Real-Time Water Management
The challenge and complexity of efficiently managing the distribution of the 55 billion m that Egypt draws from the Nile every year has prompted the country's Ministry of...
Technology Transfer Lessons from a U.S. Water District
An interceptor canal will be constructed near the end of eight laterals to collect and transport operational discharge and returned farm deliveries to a reservoir for temporary storage....
Use of Pilot Projects for Technology Transfer in Developing Countries
Pilot projects of various sizes - 25-1100 ha of farm land - have been used to demonstrate new concepts in water supply and farming practices in Sri Lanka, India and Pakistan, and they...
Gradual Development of Bores in Canal Systems
Modern computer programs for modeling unsteady flow in open channels are typically constructed using a momentum conserving form of the Saint Venant equations. This allows computation of...
Stochastic Simulation and Optimization of Irrigation Canal Network Flows
This paper investigates the effects of parametric and objective uncertainty on simulation and optimal hydraulic design of irrigation canal networks. A model of spatially-varied flow in...
Unique Water Quality Aspects of Lake Pontchartrain
Natural factors causing changes in Lake Pontchartrain, can be grouped into the following: subsidence and wetland loss due to the deterioration of the St. Bernard Delta, natural variations...
A New Panama Canal?
Based upon the 1977 treaty between the United States and Panama and an exchange of diplomatic notes among Panama, Japan and United States, a trinational feasibility study is being conducted...
The Unusual History of a Flowline Canal Within a Reservoir
This paper discusses the history of and remedial repairs to a flowline canal which carries water from the headwater of Lake Isabella in California to Southern California Edison Company's...
A Decision Support Tool for Managing Main Canal Distribution Systems
