Initiation of Air Trapping between Two Manholes in a Stormwater Conduit

Abstract

AbstractNew analysis methods are developed for evaluating the initiation of air trapping in a closed stormwater conduit between two manholes. Identifying conduits and flow conditions at risk for air trapping is a necessary precursor to identifying the ...Practical ApplicationsSevere rainstorms can cause rare, but serious, “geyser” explosions in underground stormwater piping that can blow a street-level manhole cover into the air with a 3–9 m (10–30 ft) geyser, which may last for several minutes.
