Frequently Asked Questions: Flood Model
Inventory & Data Collection
- Can I use GIS files saved under different projection systems?
- The automatic download button for getting my DEM does not take me to the USGS Seamless Website. What is the work-around?
- Internet Explorer doesn't prompt me to specifiy a download folder for the file when trying to download my DEM from the USGS Seamless Website. Instead, the file is automatically opened. How do I specify a folder?
Flood Model Operation and Analysis
- What is the maximum number of reaches that can be analyzed?
- I ran a stream network function for my study region and it does not completely correspond with a map layer of streams I already have. Is it possible to add my own stream network and use it in the flood model?
- I ran a stream network function for my study region and it does not completely correspond with the National Hydrologic Dataset (NHD), which I already have. Is it possible to add the NHD and use it in the Flood Model?
- How can I cut down the time required for a complete Flood Model analysis?
- I computed Stream Network/Hydrology/Hydraulics for a Study Region. I then deleted all previous scenarios and computed the Stream Network/Hydrology/Hydraulics again with a different Drainage Area. Now theChosen Reaches and their corresponding depth grids seem to be out-of-sync geographically. How can I fix this?
- Why are the values of Water Treatment Plant damage parameters used in the HAZUS software different from those presented in the Earthquake Model Technical Manual (Chapter 8)?
- How do I remove non-labeled problem reaches in Hydraulics with the Scenario Edit Tool?
- How do I remove problem reaches in Hydrology with the Scenario Edit Tool?

Fast Facts
HAZUS-MH can quantify the risk for a study area of any size by using GIS technology to combine hazard layers with national databases, and applying standardized loss estimation and risk assessment methodology. The GIS-based environment allows users to create graphics to help communities visualize and understand their hazard risks and possible solutions. The nationwide databases built into HAZUS-MH include datasets on demographics, building stock, essential facilities, transportation, utilities, and high potential loss facilities.
