| Abstract
|
:
|
The simulation of water distribution network can be carried out by two different methodologies. First Simulation method is the Demand Driven Analysis (DDA), in which the main objective of the governing equations is reach full demand at any demand node regardless of the available pressure; this method fails to present the real scenario when a pressure deficiency problem happened in the network. On the other hand, the second simulation method is the Pressure Driven Analysis (PDA) in which, a relation between available pressure and actual demand exists. The PDA is considered more accurate when solving the water distribution network (WDN) under abnormal conditions. Many softwares like EPANET and WaterCAD® are available to model the network in normal conditions. Since 1981, many researchers tried to model PDA using different methodologies, either by change source code of EPANET, or by adding artificial elements to the network, or by changing demand node (DN) to emitter. Until now, the automated process of solving PDA is not available in any available software. This study describes the development and application of MATLAB based program (PDA-GUI), which simulate the WDN in normal and abnormal situations. The developed program uses the methodologies of different existing PDA methods that add artificial elements to the network. It helps the decision maker to evaluate the network in different failure scenarios. The EPANET-MATLAB toolkit and EPANET library were used to implement the proposed software. It took few seconds to simulate the network deficiency by adding or removing the artificial elements. The proposed graphical user interface (GUI) is tested with three benchmark WDNs, and it is able to simulate the network in steady state and extended period simulation.
