DHALSIM

DHALSIM is a digital twin designed to study the response of water distribution systems undergoing cyber-physical attacks. The digital twin builds on a two-way interaction between a process-based numerical model (EPANET/WNTR) and a network emulation platform (MiniCPS), which is able to accurately reproduce the digital processes in the cyber-layer of the infrastructure. By emulating both cyber and physical layers, the digital twin can replicate the effects of the attacks on system hydraulics as well as the anomalous traffic and operations engendered in the cyber-network.

epanetCPA

epanetCPA is an open-source object-oriented MatLab toolbox for modelling the hydraulic response of water distribution systems to cyber-physical attacks. epanetCPA allows users to quickly design various attack scenarios and assess their impact via simulation with EPANET, a popular public-domain model for water network analysis.
