Diversion Structure for Peak Flow Reduction
The flood control requirements of a planned development in the City of Orange, California were such that the peak discharges ranging from an annual flood up to 25-year return period be...
Automation of Border and Basin Irrigation
Various methods and types of control equipment for automating border and basin irrigation are described. Mechanical gates include dual function turnout gates that both open and close and...
Field Evaluation of an Advance Rate Feedback Irrigation System
An experimental advance rate feedback system is described for furrow irrigation based upon a simple volume balance model in which surface storage during the irrigation event is neglected....
Modeling Branching Irrigation Canal Networks
A mathematical model of branching canal network has been developed based on solving the integrated form of Saint Venant equations which describing steady and unsteady, uniform and non-uniform...
Surge Flow?Automation of Surface Irrigation?At Last
The studies which led to the development of Surge Flow at Utah State University, began as an effort to automate surface irrigation systems. The first prototype models, were electric control...

Micro=Lam? LVL: A New Alternative for Timber Bridges
Laminated veneer lumber (LVL) provides a unique opportunity to obtain large structural members from ever-smaller trees. It provides the added benefit of high treatability. This paper explains...
Alternative Formulations for Water Quality Management Models
Various model formulations for water quality management are examined herein, each of which involves a somewhat different approach to the problem of determining optimal treatment levels...
Water Quality Management Through Project Operation
Harry S. Truman Dam, a multipurpose reservoir project, is located on the Osage River in the headwaters of the Lake of the Ozarks. Construction of this project created the potential to...
Reservoir Water Quality Assessment Using in Situ Microcosms
Although there are a number of techniques for determining the limiting nutrient, as will be demonstrated, in-reservoir microcosms permit in situ experiments to be conducted under relatively...
The Santa Ana River Flood Forecasting System
A real-time flood forecasting and reservoir operations simulation system has been developed for the Santa Ana River Basin, located in southern California. The system consists of generalized...
A Riverflow-Water Quality Control Model
In order to implement how regulated riverflow (control variable) impacts the salinity (output variable) under a tidal dynamic environment, a multiple input control system is developed....
Assessment & Control of Wind Created Risk During Construction
Structures under construction have been damaged by winds. The damaging winds, typically, are much lower than the design wind loads for completed structures. Little guidance is available...
Chemical Admixtures for Concrete, What is in Them for the Structural Engineer?
The paper summarizes the effect of admixtures on the economy in construction of concrete structures, on their strength, and on their durability under a variety of service conditions. As...
Integrated Information System for Traffic Control Device Management
Traffic engineers and planners have the day-to-day responsibility to maintain the safety and operational efficiency of streets and highways in their jurisdictions. Managing traffic control...
An Adaptive Control Strategy for Signalized Intersections
This paper presents a microprocessor-based computational strategy for real-time demand-responsive traffic signal control. The strategy, termed OPAC (Optimization Policy for Adaptive Control),...
Optimal Strategies for Phase Control of Wave Energy Devices
Phase control has previously been proposed for increasing energy output from wave power devices, and latching strategies have been tested for point absorbers and for pneumatic devices....
The Strategic Use of Information Systems in Urban Transportation
Computer information systems have been used by many private firms to improve the quality and change the character of the products and services they provide. Such uses of computers are...
Construction Guide Liners
Geomembrane liners for waste construction require meticulous construction, monitoring and weather watching. With much concern over the longevity of geosynthetics, many overlook the extreme...
Supervisory Control System Design
This paper presents supervisory control concepts, elements of a typical system, testing activities, project management, and the procurement process. Modes of control systems are discussed...
