Abstract:
A computer-based simulation model was developed to quantify the seismic damage that
may occur in water supply networks and to suggest restoration strategies after such events. The model
was designed to produce probabilistic seismic events and determine the structural damage of facilities.
Then, the model numerically quantifies the system restoration rate over time by connecting it with
a hydraulic analysis solver. The model intends to propose superb restoration plans by performing
sensitivity analyses using several restoration scenarios. The developed model was applied to an actual
metropolitan waterworks system currently operating in South Korea and successfully suggested the
most efficient restoration approaches (given seismic damage) to minimize the complete recovery
time and suspension of water service. It is expected that the proposed model can be utilized as a
decision-making tool to determine prompt system recovery plans and restoration priorities in the
case of an actual seismic hazard that may occur in water supply networks.
