     "text": "Using a flood inundation map library to estimate where floodwaters will go and how deep they will be is crucial for planning and preparing for floods. By performing loss-estimation modeling, the potential physical, economic, and social impacts of disasters can be calculated, helping communities anticipate the effects of flooding and identify specific strategies to reduce losses and speed recovery."

     "text": "Alternatively, the Loss by Census Block HAZUS feature gives more detailed loss estimates for each census block in the study area. Drop down menus allow the user to select from over 90 different types of damage and loss categories. Census blocks are colored to represent representative values for each stage interval (fig 8)."

   {
     "@type": "TextObject",
     "text": "HAZUS analyses are first run offline for each incremental stream stage (height) over the selected FIM stream reach. For example, a stream reach with inundation maps and depth grids for 15 different stream stage increments would require 15 different HAZUS analyses. Loss estimates are compiled at two scales. The Quick Assessment displays loss estimates for the entire study area, including displaced population, short-term shelter needs, economic property loss, and lost income from business interruptions (fig. 7). The Quick Assessment option also includes regional statistics for the study area, including area, number of Census Blocks, number of buildings (residential and total), population, and total value of exposed buildings. Both Quick Assessment and Loss by Census Block data are calculated for each stream stage increments and uploaded to the USGS Flood Inundation Mapper."

     "text": "HAZUS-MH is the principal software used to assess flood risk to affected populations, buildings, and other infrastructure in the U.S. However, while HAZUS is able to generate reliable assessments of flood risk, its usefulness is limited because it can only be run on a workstation by a trained operator using ESRI\u2019s ArcGIS software. In 2010, the USGS and FEMA began an effort to solve this problem by integrating HAZUS flood risk analyses with the USGS-produced flood-inundation map libraries and making these data available online."

     "@type": "TextObject",
     "text": "One commonly used loss-estimation model for flooding is HAZUS, which is maintained by the Federal Emergency Management Agency (FEMA). The HAZUS-MH loss-estimation application is a nationally applicable standardized methodology that contains models for estimating potential losses from earthquakes, floods, and hurricanes. HAZUS is used for preparedness and response as well as mitigation and recovery. HAZUS uses GIS (Geographic Information Systems) technology to illustrates the limits of identified high-risk locations and allows users to visualize the spatial relationships between the human populations and assets or resources."
