Case Studies?Semi-Closed Pipeline Systems, Orange Cove and Solano Irrigation Districts
The Harris Float Valve is a simple mechanically leveraged valve connected to a float, which activates the valve with the rise and fall of the water surface on the down stream side of the...
Case Study?Open Pipeline System, Coachella Valley Water District
A supervisory canal control system installation was started in 1966, seventeen years after start up, and a major upgrading was completed in 1983. The canal delivery system now has a central...
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,...
Maintenance of Automated Pumping Plant Controls
Westlands Water District, located in the Central San Joaquin Valley in California (Fig. 1) includes over 600,000 acres of agricultural land and is part of the San Luis Unit of the U. S....
Implementation and Management of a High Technology Irrigation System
Eastern Oregon Farming Company (EOFC) irrigates 12,000 acres using a fully pressurized irrigation system. In 1981, the system was operated with minimal flow and pressure measurements and...
Instrumentation: Canal De Provence
A report describing the Canal de Provence and its specific hydraulic regulation system, 'dynamic regulation', is presented in another conference paper. The present...
Instrumentation for Automated Irrigation Systems
Remote site instrumentation sensors are vital components in automated irrigation systems, enabling measurement of water levels, flows and gate positions. It is desirable to select sensors...
Data and Control Communication Methods for Delivery System Operations
The selection of a communication system for the automation of a canal system requires careful consideration of the type of canal system operation desired, the location of the facilities...
Overview of Financial and Economic Considerations
The financial and economic analyses of plans to rehabilitate and automate irrigation water delivery systems are complex technical exercises that require the expertise of professional economists...
Financing Options for the Operation, Rehabilitation, and Automation of Irrigation Water Delivery Systems
The paper discusses potential sources of financing for irrigation improvements and outlines many methods for securing funds. Irrigators who are in need of funds to improve or repair their...
Yakima-Tieton Irrigation District Rehabilitation Program
The Yakima-Tieton Irrigation District obtained funding from the U. S. Bureau of Reclamation and the State of Washington to replace an open canal and lateral irrigation delivery system...
Economic Analysis of Irrigation Rehabilitation Projects
This paper discusses the assessment of the costs and benefits of irrigation rehabilitation and modernization projects. It summarizes the methodology used at the World Bank to assess the...
The U.S. Geological Survey's National Real-Time Hydrologic Information System Using Goes Satellite Technology
The U. S. Geological Survey maintains the basic hydrologic data collection system for the United States. The Survey is upgrading the collection system with electronic communications technologies...
The NOS Experience in Real-Time Measurements of Tidal Currents
NOAA'S National Ocean Service (NOS) uses the term RADS, Remote Acoustic Doppler Sensing, for a new class of oceanographic instruments that uses acoustic backscatter to probe...
Simulation of Sediment Transport in Coastal Water
The sediment-contaminant transport code, FETRA, coupled with the hydrodynamic model, CAFE-I; and the wave refraction model, L03D; were applied to Pacific coastal water. The FETRA model...
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...
Carichar?Mobile Bed Modeling with Graded Sediments
CARICHAR is a new system used for the computation of sediment transport. The coupled calculation of both water and graded sediments transport allows the simulation of sorting and armoring...
Hydraulic Availability Evaluation of Urban Water Distribution Systems
This paper presents a concept for evaluating urban water system reliability using an extended period hydraulic simulation model in conjunction with mechanical availability analysis. Reliability...
Joint Consideration of Pipe Breakage and Pipe Flow Probabilities
Two issues of distribution network reliability, namely, probability of pipe failure and probability of the design flow being exceeded have been discussed. Expressions containing measures...
Optimal Design of Large Scale Water Distribution Systems
This paper presents a methodology for the design of least cost water distribution systems. The advantage of the formulation compared to the other techniques in the literature is that it...
