Abstract: In large combined- and storm-sewer systems it is impractical to model every pipe, manhole, and component of the system. Time and budget constraints, combined with a lack of relevant input data, compel modelers to make ...

Abstract: The community of Ntisaw in Northwestern Cameroon originally partnered with the Engineers Without Borders chapter at the University of Illinois at Urbana-Champaign in 2008 to design a gravity-fed distribution network for ...

Abstract: The Green-Ampt method is a physically based model for partitioning rainfall into surface runoff and infiltration. This method is widely used in infiltration practice because of its simplicity and the ease of obtaining the ...

Abstract: This work is part of a long term project which aims at developing a hydraulic model for real-time simulation of unsteady flows in sewers ranging from gravity flows, to partly gravity–partly surcharged flows to fully ...

Abstract: This paper focuses on the formulation and assessment of a second-order accurate finite volume (FV) shock-capturing scheme for simulating one- and two-phase water hammer flows. The two-phase flow model is based on the ...

Abstract: A junction and drop-shaft boundary conditions (BCs) for one-dimensional modeling of transient flows in single-phase conditions (pure liquid) are formulated, implemented and their accuracy are evaluated using two computational ...

Abstract: 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 surface-combined sewer system. ...
