Abstract:
A discrete event simulation model is used to evaluate the effectiveness of key post-earthquake water supply restoration strategies that the Los Angeles Department of Water and Power (LADWP) plans to use following a major earthquake. The strategies are: (1) maximising the groundwater pumped into the system, (2) connecting raw water emergency storage reservoirs, (3) rationing water use, and (4) all three. For each of five realistic earthquake scenarios the restoration with and without implementation of the key restoration strategies are compared. The results suggest that opening the reservoirs and rationing are effective post-earthquake restoration strategies that would help to minimise the water outages.
