CAFlood was successfully applied to deliver 120,000 water main burst scenario simulations across London within a week, saving an estimated 27 years computing time if conventional hydraulic models were used. Experimentation was carried out on a range of different sized possible pipe bursts, and a comparison with the speed and accuracy of the industry-standard InfoWorks system was made.

Shows the varying depths (between 0 and 10.92 meters) and extent at 2 hours of simulation time for a 2,000 Millimeter pipe burst from: (a) InfoWorks output (runtime: 19m47s); (b) CAFloodPro 0.01s minimum time step output (runtime: 3m33s); (c) CAFloodPro 0.03s minimum time step output (runtime: 1m46s); (d) CAFloodPro 1.0s minimum time step output (runtime: 15s);
