Abstract: Pumping systems are a topic of great relevance in the teaching of civil and environmental engineering courses related to urban water infrastructure. One key component of this teaching is the diameter selection of transmission ...

Abstract: Stormwater systems are subject to operational issues while undergoing rapid filling during intense rain events. In various instances, air–water interactions take place, and it is possible that the air located in the headspace ...

Abstract: Stone masonry is the oldest building material that survived until today, being used all over the world, particularly in impressive historic structures as an evidence of the achievements of ancient cultures. Stone walls are ...

Abstract: Deep storage tunnels are an alternative to mitigate combined sewer overflows, but they may develop transient flow problems during rapid filling conditions. Such issues include excessive surges, formation of pipe-filling ...

Abstract: Below-grade storage tunnels in stormwater systems are usually designed to operate in a free-surface flow regime. However, intense rain events may trigger flow regime transition to pressurized flow, which results in operational ...

Abstract: Deep storm-water storage tunnels may undergo pressurization during intense rain events. In the process, air pockets may become entrapped and pressurized, causing significant flow changes. Currently, the role of nearby surge ...

Abstract: In order to avoid operational issues related to entrapped air in water transmission mains, water refilling procedures are often performed carefully to ensure no pockets remain in the conduits. Numerical models may be a ...

Abstract: Among the various applications of the shallow water equations (SWEs) is the simulation of gravity currents (GCs). The SWEs are used as an alternative to track GC motion without explicitly dealing with turbulent processes, ...
