Abstract: It is demonstrated that dual drainage systems can considerably reduce flood risks when compared with single conduit urban storm drains. Underground pipes should only convey minor events as they flow fast when full. Shallow roadways or flood plains will take the balance at lower velocieties and therefore reduce peaks. Surface conveyance systems can also take extreme events with little increase in flow depth.
