Design of Semi-Closed Pipeline Systemsby John L. Merriam, California Polytechnic State Univ, San Luis Obispo, CA, USA,
Document Type: Proceeding Paper
Part of: Planning, Operation, Rehabilitation and Automation of Irrigation Water Delivery Systems
Semi-closed pipeline systems controlled by downstream activated float valves permit low pressure pipeline systems to communicate information from the outflow location back to the source as to the outflow requirement and to automatically convey the needed water supply. Such capabilities facilitate the use of flexible schedules and reduce operational labor requirements compared to the prevalent open pipeline systems. The advantages and the design precedures are described.
