6 UDINEE Workshop N. Benbouta. Dec. 15 2015. UDINEE Workshop. Ispra (Italy). P. 6  Atmospheric transport and dispersion of CBRN agents in dense urban environments identified as a key gap in the CSSP and previously in CRTI created post 9/11 by RDDC.  Existing operational non-urban mesoscale plume models have limitations for emergency response to CBRN events in urban environments.  Under the projects CRTI 02-0093RD and CRTI-07-0196TD, a prototype of the Canadian Urban Dispersion Modeling System (CUDM) was developed. Context CUDM: Canadian Urban Dispersion Modeling System CUDM System aims to fill this gap and to be used for scenario planning, operational response and post-event analysis. CRTI & CSSP
