    Urban water distribution systems (WDSs) are vulnerable to accidental and intentional contamination incidents that could result in adverse human health and safety impacts. This thesis research is part of a bigger ongoing cyberinfrastructure project. The overall goal of this project is to develop an adaptive cyberinfrastructure for threat management in urban water distribution systems. The application software core of the cyberinfrastructure consists of various optimization modules and a simulation module. This thesis focuses on the development of specific middleware components of the cyberinfrastructure that enables efficient seamless execution of the core software component in a grid environment. The components developed in this research include: (i) a coarse-grained parallel wrapper for the simulation module that includes additional features for persistent execution and hooks to communicate with the optimization module and the job submission middleware, (ii) a seamless job submission interface, and (iii) a graphical real time application monitoring tool. The threat management problems used in this research is restricted to contaminant source characterization in water distribution systems.
