Abstract

Sampling design for water distribution networks G. Del Giudice & C. Di Cristo Department of Hydraulic and Environmental Engineering G. Ippolito, University of Naples "Federico II", Italy Abstract Modeling activities, specifically model calibration, need sensor measurements. Since data collection is expensive and time-consuming, ineffective measurements should be avoided. For this reason, it is important to have a method for designing the field data collection that will give the most useful information. While sampling design problems have been studied more in groundwater systems, there are only few applications to water distribution networks. In this paper three different sensitivity-based methods for selecting the worthwhile sensor location in water distribution network are compared. The covariance matrix method, previously applied to identify the most useful loading condition under which to take measurements, is adapted to a sampling design problem. Since this method considers the correlation
