| Research Abstract |
The present study focuses on an abrupt increase in flow rate and a decrease in water pressure of water distribution system in spite of no damage to pipeline during an earthquake. First, a questionnaire survey on unusual behavior of water distribution system during an earthquake was conducted to large-scale waterworks bureaus in Japan. We clarified that sloshing of water in receiving tank induced by a long period, long duration seismic motion induce an error of water level sensor in a receiving tank. Effect of a long period, long duration seismic motion by mega earthquake to water distribution system was discussed
