PROJECT REVIEW COMMITTEE DECISIONS
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.
Component 1: development of a “building aware” model for urban flow prediction (UrbanSTREAM)
Component 2: inclusion of subgrid-scale urban parameterization in meso-scale NWP model (GEM-LAM)
Component 3: coupling of microscale flow model with “urbanized” GEM-LAM.
Component 4: development of a lagrangian stochastic model for prediction of urban dispersion (UrbanLS).
Component 5: validation of fully coupled multi-scale modeling system for urban flow using field study verification data.
Component 6 (new): in the context of PSTP, collaboration work with US NARAC center (LLNL) and development of methodologies for determination of emission source distribution (source reconstruction).

3.3 Project AssumptionsThe Project Plan assumes that:
Funding as approved under the project will remain available and disbursed on time: OK.
Start date of research and development for components 1 and 4 is based on having a contract in place with PWGSC by August 1, 2003…: OK
New and qualified personnel will be hired ….: OK
Key existing personnel will be available throughout the project.
We were able to react relatively quickly when Claude Pelletier left the project last fall. A new employee was hired. Otherwise we have been able to maintain the right level of required staff to advance the project.
Key equipment (computing infrastructure) and key datasets will be available:
Generally speaking main computing infrastructures and datasets have been available. However, there has been some slow downs and risk associated with the significant delays of the IBM supercomputer upgrade and associated systems. This is a file which we are monitoring closely. To minimize this risk we have purchased a set of high performance front end nodes (40 node InfinitiBand cluster) which should be available for our use by August 2006. We expect to be able to run our tests on this machine.
3.4 Project Constraints
A significant component of the Validation phase of the project (component 5) is constrained by the availability of flow and dispersion data sets to be acquired during JUT 2003 in Oklahoma City: OK. We have access to OKC datasets and as well to MUSE1-2 datasets.
Unfortunately, no access is expected to the New-York City Tracer experiment for some years.
For all Federal Departments involved in the project
· Risk: A national or international crisis or other immediate events triggering emergency response will delay the conduct of the project
Mitigation: CRTI secretariat to be advised immediately. Components of the project to be delivered by private companies will not be affected. Project plan for deliverables will be modified accordingly, financial impacts will be assessed and the Charter will be adjusted.
Defence R&D Canada -- Suffield · Risk: Transfer of mathematical urban flow models to Waterloo CFD Engineering Consulting Inc. in a format understood by all is problematic Mitigation: Ongoing communication with project partners at Waterloo CFD Engineering Consulting Inc. (e-mail, teleconference, and meetings as needed) to allow for smooth transfer of DRDC Suffield mathematical models to Waterloo for numerical solution coding --- Modelling Group at DRDC Suffield will collaborate closely with the CFD Modelling Group at Waterloo to ensure fidelity in the model transfer and in the implementation of the proposed flow models· Risk: Delay in obtaining data from the Joint Urban Trial (JUT) 2003 Mitigation: Ensure that all appropriate security clearances are granted· Risk: IP issues and disputesMitigation: Pass information to IP office as soon as possible for resolution
Environment Canada – Canadian Meteorological Centre (CMC) and Turbulence (22-26 May 2006 in San Diego CA) dealing with Numerical simulations of the urban boundary layer observed during Joint Urban 2003 (Mailhot et al.).· Risk: Availability of qualified technical staff to undertake certain phases of the project.Mitigation: One Research Scientist (RES) and one Post-doctoral Fellow (PDF) with the required expertise are in the process of being hired to support work on this project full time.· Risk: Availability of staff for Project Management and Coordination Mitigation: New staff member to aid project manager (Mr Michel Jean) with project coordination has been hired.· Risk: Difficulty in the implementation and/or porting of code to the new IBM massively parallel supercomputing platform (which is currently being brought on-line at Canadian Meteorological Centre).Mitigation: New RES to be hired with strong parallel computing background.Mitigation: Resources have been set aside at CMC to manage this issue.· Risk: Difficulty in coupling the micro and meso-gamma scale model.Mitigation: Maintain close on-going collaboration with Waterloo CFD Engineering Consulting Inc. microscale model development and implementation team.Mitigation: Provide Waterloo CFD Engineering Consulting Inc. Implementation Team with full documentation for the GEM-GEM LAM model.Mitigation: Employment of a common GUI between EC-CMC and Waterloo CFD Engineering Consulting Inc.(CMC Modeling Toolbox will provide the common interface). · Risk: Lack of attention to needs of end users (first responders).Mitigation: Work with CMC to understand existing emergency response system and FNEP TAG requirements.
Our strong involvement with CRTI project 05-0058TD (inoperability framework in the Vancouver area) will be our
main initial connection with the first responders.
· Risk: Tracer data from Oklahoma test site is delayed.Mitigation: Consultation with project team members from AECL and HC-RPB who have extensive experience in model validation.Mitigation: Additional data from AECL and/or HC-RPB could be usedfor model validation in place of the expected comprehensive urban flow and dispersion data sets to be acquired in JUT 2003.· Risk: Oklahoma City vector format GIS data not compatible with EC-CMC softwareMitigation: Consult with team members from DRDC Suffield and WaterlooCFD Engineering Consulting Inc.Mitigation: Ensure that the necessary graphics packages are available at EC-CMC.Mitigation: Ensure that qualified staff are available to manipulate the vector format GIS data.· Risk: Model predictions do not agree with experimental data within acceptable margins (defined in the literature)Mitigation: Allow time for model revisions based upon initial testing.Mitigation: Allow time for a documented discussion of project limitations.
J.D. Wilson & Associates (Dr J.D. Wilson) and Turbulence (22-26 May 2006 in San Diego CA) dealing with Numerical simulations of the urban boundary layer observed during Joint Urban 2003 (Mailhot et al.).
· Risk: Delay in the coupling of the micro and meso-gamma scale model to delay Lagrangian Stochastic (LS) model verification and validation.Mitigation: Offline model testing with in house data sets until coupled code complete --- LS model validation (primarily urban dispersion model validation can begin immediately by coupling model to the urban microscale flow model to investigate predictive accuracy of the model at short range [up to about 2 km]).
Atomic Energy Canada Limited (AECL)
· Risk: Access to classified information is denied.Mitigation: Reliance on other team members already having obtained the necessary security clearance. · Risk: Access to sensitive measurements at AECL CRL is denied to project members.Mitigation: An agreement with the responsible body at AECL describing the use that project members will make with the data and a review of material to be published by AECL to eliminate sensitive information
Health Canada (Radiation Protection Bureau)· Risk: Availability of data sets for verification and validation of the modelling system.Mitigation: Preparation of data sets in parallel as modelling system is being developed. Work is currently underway along those lines through the joint work between HC RPB and EC CMC for assessment of a noble gas analyzer in the context of the Comprehensive Nuclear-Test-Ban Treaty.
