the sequence of events started with a prediction of structures likely to be affected by both a 100- and 500-year flood event (Figure 3). this first representation would provide responders and natural gas infrastructure operators with the ability to conduct pre-event planning activities for their response (Figure 2). this capability is considered an important first step to improving system resilience, including the ability to limit the impact of the event and to shorten the length of time critical facilities are without access to natural gas. the flood event was then represented at three arbitrarily chosen points in time: 1) 24 h in (Figure 4) 2) 72 h in (Figure 5) 3) one week into the flood (Figure 6). the system would function continuously throughout an event, providing real-time updates as information is made available. this portion of the demonstration was conducted live by directly communicating status from Figure 4. A flood event 24 h in, where active utilities are flagged as affected. Figure 5. A flood event 72 h in. A full-scale disaster is shown, especially in District 1. Services and structures affected in predicted flood zones and nonpredicted impact areas (yellow) are observed. Impassable road sections are shown in red.
