Effects of Earthquakes to California’s Water Distribution System

By Pavlo Chrysovergis, P.E. | Geo-Institute Chair



On July 18, 2019, the Orange County Branch and Geo-Institute co-hosted a luncheon featuring Professor Scott J. Brandenberg of UCLA, who presented on “Effects of Earthquakes to California’s Water Distribution System.” Professor Brandenberg discussed an extensive research study on the Sacramento/San Joaquin Delta, which included field testing, centrifuge modeling, laboratory testing, development of fragility functions, and development of a system reliability analysis procedure.

With Magnitude 6.4 and 7.1 earthquakes occurring in Ridgecrest, California two weeks prior to the luncheon, this topic was particularly relevant to the 90+ local members who attended. Professor Brandenberg also presented a recap of his observations from a field reconnaissance trip to Ridgecrest as a part of the Geotechnical Extreme Events Reconnaissance (GEER) Association.

Thanks to everyone who attended and to our sponsors: Western Ground Improvement, Hayward Baker, Middle Earth Geo Testing, and California Nevada Cement Association!
