Abstract
This paper presents the results of a hydraulic transient analysis for a 42.6 km (26.5 mile) long treated water pipeline near Los Angeles, California. Simulations were performed for controlled closing of an in-line valve structure and safe gate close times were recommended to prevent the pressure from exceeding the maximum allowable pressure of the pipeline. Surge control measures were also developed to eliminate the possibility of vapor cavity formation and large magnitude negative pressures in the pipeline following both controlled closure and accidental sudden closure of the in-line valve structure.
