One potential problem affecting below-grade storm-water storage tunnels is the occurrence
of geysering, which is defined as the return of conveyed water to grade. Most investigations …

Events that are referred to as geysers have been observed in storm-water or combined
sewer systems and are associated with jets of water rising through manholes to a …

In urban stormwater systems, a rapid increase in water inflow can cause the entrapment of
air pockets and subsequent ejection of air/water mixture, commonly known as storm …

Geysers, which involve the explosive release of water through vertical shafts connected to a
nearly horizontal pipeline, have been attributed to either pipeline surge or the release of air …

Geysers can occur in storm sewer systems during heavy storm events, leading to public
safety concerns. In this study, a physical model as well as a transient three-dimensional …

Geyser events have been observed during the filling of large diameter conduits such as
CSO storage tunnels which may experience an explosive release of water and air mixtures …

Transient flow events can potentially damage infrastructure and threaten public safety in the
vicinity of violent flow eruptions that occur where tunnel drop shafts interconnect with the …

Storm water and combined sewer systems are subject to rapid filling during intense rainfall
events. These large-sized systems require a significant amount of air to be vented during …

Storm geysers increasingly occur in sewer systems under climate change and rapid
urbanization. Mitigation measures are in great demand to avoid safety problems. In this …

A storage tunnel system is the critical infrastructure of urban drainage systems, in which the
rapid filling of water and release of trapped air can lead to the “geyser” phenomenon. This …
