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...
Underwater Inspection of Hydraulic Structures
Improvements in diving equipment, and underwater testing and instrumentation devices in recent years have increased the value of underwater inspections and reduced the cost. This paper...
Adding a Climatic Interface to Electronic Irrigation Controllers
Automated irrigation systems have traditionally relied on a time based controller set to operate the irrigation system for a specific duration and frequency. To determine the duration...
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...
Three Automatically Erected Folding Spans
The U. S. Navy has identified three rapidly erected bridges. Each is capable of spanning 400 feet (120 m) with a 70 ton (63 tonne) live load at mid-span. Each will also fold into a 15...
