  1. What is HAZUS-MH? HAZUS-MH is a planning tool that estimates damage and losses resulting from natural hazards • It is an estimation tool, NOT a deterministic tool • It is a planning tool, NOT an engineering tool • Engineering-level data (i.e. Hydrology & Hydraulic studies) can be input to increase accuracy, but results still produce planning-level estimations • It also assesses population needs related to emergency management • It also allows users to compare results from different study case scenarios, including mitigation actions HAZUS-MH is an empirical model based on observation and experiment

  2. www.THMP.info Easy to Use (less expensive) H & H Highly Accurate (more expensive)

  3. HAZUS-MH: Family of Products • Models HAZUS-MH is a multi-hazard (MH) application Flood, Hurricane (Wind), Earthquake • Data Integration Tools • Inventory Collection And Survey Tool (InCAST) • Building Import Tool (BIT) • * Flood Information Tool (FIT) • Linkage to 3rd-party Models • Areal Locations of Hazardous Atmospheres (ALOHA) • Flood Waves (FLDWAV)

  4. HAZUS-MH: Technical Components • Software: Custom GIS (geographic information system) • Runs on ESRI products; ArcGIS and Spatial Analyst • ESRI products must be acquired separately • Spatial Analyst required for Flood Model only • HAZUS-MH is free from FEMA <www.fema.gov/hazus> • Current HAZUS-MH version (MR1) runs on ArcView 9.0 • Data: National data sets • Inventory of assets (buildings, infrastructure, population/demographics, etc.) • Users may modify data sets or model factors • Users may add their own data

  5. ArcGIS / ArcView & Spatial Analyst www.esri.com

  6. HAZUS-MH: Technical Notes • Operating System Requirements • Windows XP SP1 • Windows 2000 SP1 – SP4 • GIS Requirements • ArcGIS 9.0, SP1 • Spatial Analyst extension (Flood Model only)

  7. HAZUS-MH: Technical Requirements From FEMA Web Site ArcGIS and HAZUS require significant computing power and resources (Computer hard disk space varies per dramatically per User)

  8. HAZUS-MH: Methodology 5. Estimate Losses/Needs 4. Estimate Damage 3. Overlay Inventory 2. Define Flood Hazard 1. Define the Geographic Area for Analysis

  13. Applications in Mitigation Planning & Emergency Management Emergency Preparedness Response & Recovery HAZUS-MH Loss Reduction (Mitigation)

  14. HAZUS Applications:Emergency Preparedness • Develop emergency response plans • Temporary housing • Debris removal • Emergency power and water • Emergency medical services • Evacuation/emergency route clearance • Organize response exercises

  15. HAZUS Applications:Mitigation • Mitigation Assessment • Identify ‘at-risk’ communities • Mitigation Measures • Strengthen existing structures • Strengthen window/door openings and siding • Mitigation Programs • Adopt and enforce hazard-resistant building codes • Land use planning

  16. HAZUS Applications:Response and Recovery • Post-disaster damage assessment and ground-truthing • Response planning for critical transportation outages • Identify critical infrastructure • Recovery action planning • Long-term economic recovery planning

  17. Benefit Summary • HAZUS-MH allows user to: • IDENTIFY vulnerable areas that may require planning considerations • ASSESS level of readiness and preparedness to deal with a disaster before disaster occurs • ESTIMATE potential losses from specific hazard events (before or after a disaster hits) • DECIDE on how to allocate resources for most effective and efficient response and recovery • PRIORITIZE mitigation measures that need to be implemented to reduce future losses (what if)

  18. FEMA: Ordering HAZUS • HAZUS-MH Overview • Brochures/Materials • Order Information • Application Case Studies www.fema.gov/hazus • National Conference Info • FEMA/EMI Training Schedule • General Contact Info • Technical Support/FAQ’s

  19. Flood Hazard Model Initial Step: Create/Open Study Region RIVERINE 2. Generate Stream Network 4. Run Hydrology 1.Define Topography 5. Compute Hazard 3. Define Study Case Enter 100-yr Elevation Segment Shoreline COASTAL Final Step: Run Analysis & View Results

  20. Initial Step: Create a Study Region

  21. Inventory Square Footage

  22. Inventory Dollar Exposure

  23. Flood Hazard • HAZUS computes: • Floodplain Boundary • *Flood Depth Grid* FloodplainBoundary Flood Water Elevation Normal Water Elevation (main channel) • Flood Water Elevation • Ground Elevation • = Flood Depth Vertical Datum: Sea Level

  24. 1. Define Topography

  25. 2. Generate Stream Network

  26. 3. Select a Study Case

  27. 4. Run Hydrology

  28. 5. Compute Hazard(Run Hydraulics)

  29. Final Step: Run Analysis
