  Micropolis is a virtual city that is used for various studies, such as
modeling and analyzing water networks. In this paper we model the various
interdependencies between three major infrastructures in Micropolis, the power
system, the communication network and the water network, in order to study
cascades effects between them. Specifically, we develop open hybrid automata
models for the main components of the three infrastructures and then composed
them together based on their interdependencies.
