Simulation of Water Networks Remodeling-Linear-case

Abstract

The problem of the management of water resources is more and more important on a world scale. In particular, there is a requirement for novel concepts helping to solve the water management problem i. e. numerically efficient tools supporting optimal design (redesign) process for water networks. The paper deals with the simulation of network remodeling and demonstrate how virtual distortion generated a chosen branch (e.g. in the branch No.4) can simulate the network modification due to total blocking flow in this branch. To this end, the condition of flow vanishing in the branch under remodelling should be postulated, where the resultant state of flow redistribution is calculated from the formulas superposing linear response of the original network configuration and the component induced by unknown virtual distortion. Then making use of the analytical network model (cf.Refs.3,1) of this installation and using presented below, the so-called Virtual Distortion Method (VDM), simulation of network remodeling can be performed
