N2 - In recent years, automated systems of supervisory control and data acquisition (SCADA) have been widely used in water distribution networks, which have made the distribution system vulnerable to cyber-Attacks. One of the main limitations of the previously proposed cyberattack detection models is that tampering the SCADA's pressure readings would not be reflected on the estimated nodal demands. As a result, cyber-Attacks caused by such manipulations would not be detected. To address this challenge, this paper incorporates pressure readings in the detection algorithm as a constraint and develops a mixed integer nonlinear programming (MINLP) formulation to estimate the nodal demands of a network, as well as its flow rates and nodal pressure readings. These values are estimated using the SCADA readings for link flows, pump's status, tank's water level, and total demand of a district metering area. Nodal pressure heads are calculated using Bernoulli's and Hazen-Williams equations and pump's head equation.
