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...
Aids for the Hazard Classification of Small Dams
The last few years have seen a large growth in the tools available to the engineer to better determine the risk of failure in earth dams. One of the models developed is the National Weather...
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...
Modeling Cohesive Sediment-Pollutant Interaction in Surface Waters
Particulate and dissolved pollutant transport rates are predicted using a pollutant transport modeling system. The latter is a finite element model capable of simulating two-dimensional...
On the Definition of Fluid Mud
Fluid mud is a near-bed, high density cohesive sediment suspension layer which is a common cause of estuarial and nearshore sedimentation. It is noted that for a given sediment-fluid mixture,...
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...
An Analytical Approach to Cohesive Sediment Transport
Simulation of mud transport processes is adequately achieved by using the unsteady advection-diffusion equation along with the appropriate source and sink terms. The effects of selective...
Suspended Material Transport at New Bedford, MA
Evaluation of suspended material migration was a task in a study of sediment-associated contaminant migration. New Bedford Harbor is a vertically well-mixed, shallow estuary with little...
Numerical Model Evaluation of Advance Maintenance
Improving and maintaining navigation harbors and channels is one of the key functions of the US Army Corps of Engineers. The present cost-sharing system and the increasing costs associated...
Numerical Evaluation of Training Structures
A technique to evaluate estuarine training structure performance in reducing localized maintenance dredging requirements using the US Army Corps of Engineers TABS-2 numerical modeling...
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...
