Water quality is a very important issue related to people health, but it is not usually considered in water distribution networks (WDNs) design. In this paper, new constraints such as free residual chlorine and the quality performance index are incorporated into the least cost design of water distribution networks. EPANET2 was applied for the hydraulic and quality analysis of water distributio...

Background: This study aimed to evaluated trends for iron and manganese concentrations in wells, reservoirs, and water distribution networks in Qom city during the summer of 2012. Methods: This was a cross-sectional study. The studied scopes consisted of groundwater (60 wells), reservoirs (10 tanks), and water distribution network (33 points). One sample was taken from each source monthly. Stat...

Measuring sensitivity of hydraulic structures is considered as an approach for evaluation of water projects performance, due to lower distribution efficiency in Irrigation and Drainage project schemes. Sensitivity analysis approach for irrigation structures is one of flow analysis methods which are developed in recent years in order to measure the behavior of flow in hydraulic structures in an ...

undoubtedly, sampling design is an important issue in monitoring of a water distribution network (wdn). the aim of the current paper which focuses on the localization of samplings, is to present a practical method for optimization of the position and number of the pressure measurements. this method works based on the assumption of some leakages in a network and searching for them by nodal press...
