The objective of this project is to develop and validate an integrated, state-of-the-art, high-fidelity multi-scale modeling system for the accurate and efficient prediction of urban flow and dispersion of CBRN materials.

Prototype to be ready in early 2007

Development of this proposed multi-scale modeling system will provide the capability to perform real-time modeling and simulation tool to predict injuries, casualties, and contamination and to make relevant decisions (based on the strongest technical and scientific foundations) to minimize the consequences based on a pre-determined decision making framework.
