- Abstract
- Several past earthquakes and their impact on water systems are described, and characteristic damages which resulted are pointed out. Because of the importance of water lifeline networks after earthquakes, a method for analysing the impact of earthquakes on their system performance is developed. The part of this analysis which deals with ground failure-induced damage to pipes in poor soil is applied to the water system of the Metropolitan District Commission, Commonwealth of Massachusetts. Various levels of pipe damage are simulated, and the impact of these damage levels on system performance is evaluated.
