Abstract: Necessary and sufficient conditions for solving flow-constrained networks are developed. These conditions are predicated on the interrelation between the decision variables specified and the network-flow hydraulics. They ...

Abstract: An explicit algorithm is presented for directly determining a variety of design, operating, and calibration parameters for pipe networks. The problem solution is based on the reformulation of the steady‐state network ...

Abstract: A simple and efficient heuristic screening methodology is presented for use in the regional planning of wastewater‐treatment systems. The proposed approach provides a powerful tool to aid practicing engineers in the ...

Abstract: A comparison is made between the formulation and computational performance of four numerical methods for modeling the transient behavior of water quality in drinking-water-distribution systems. Two are Eulerian-based (the ...

Abstract: In 1993 P. F. Boulos and T. Altman developed an efficient explicit scheme for determining steady state water quality in a distribution system for conservative and zero-order reacting constituents. This approach is extended ...

Abstract: An explicit dynamic water‐quality modeling algorithm is developed for tracking dissolved substances in water‐distribution networks. The algorithm is based on a mass‐balance relation within pipes that considers both advective ...

Abstract: An efficient system simulation methodology that solves the contaminant-transport problem in drinking-water-distribution systems is developed. The method can be effectively used for modeling the time-varying interaction of ...

Abstract: Nearly all distribution systems in the United States include storage tanks and reservoirs. They are the most visible components of a water distribution system but are generally the least understood in terms of their impact ...
