      <abstract>Recent developments in digital terrain and geospatial database management technology make it possible to protect this investment for existing and future projects to a much greater extent than was possible in the past.  The minimum requirement for hydraulics data includes input and output files for all hydraulic models and spatial datasets that are needed to implement the models.  (Source: FEMA Guidelines and Specs, Appendix N)</abstract>
      <purpose>Development of a hydraulic model to provide water-surface elevations for floodplain mapping requires significant investment in time and resources to obtain and process topographic survey data including cross-section and bridge surveys.</purpose>

    <logic>Hydraulic analysis uses all valid existing flood elevation, survey, hydrologic analysis results and other pertinent information for the study area.  FEMA approved models are used to compute water surface elevations for required flood events.  Computed water surface elevations and topographic data are used to delineate flood hazard boundaries.  Roughness coefficients are carefully selected to represent the conditions along stream beds and banks. </logic>
    <complete>Hydraulic analysis provides water surface elevations at different locations along the stream and for different flooding events.  Hydraulic submittal includes key physical data used in the process, model parameters and model input.  Data developed in surveying and hydrologic analysis are incorporated in hydraulic analysis.  Results of hydraulic analysis are used to map Special Flood Hazard Area (SFHA) boundaries.  Selection of model parameters (e.g. roughness coefficients, expansion and contraction coefficients, etc) is supported by additional information (e.g. landuse, aerial photo, etc).  Model boundary conditions are carefully selected and justified.  Modeled velocities are checked for potential erosion.</complete>

        <procdesc>For all streams studied by approximate methods, GIS-based automated hydraulic methodologies were employed.  These streams are supported by geo-referenced HEC-RAS models.  While hydraulic structures were not incorporated into the models, cross sections were automatically generated and manually adjusted, where applicable, to capture areas of hydraulic contraction.</procdesc>

    <overview>
      <eaover>The Hydraulic submittal is made up of several data themes containing both spatial and attribute information.  These data represent the extent of flooding and the water surface elevations for the subject area.  The spatial data files and attribute tables include stream centerline, cross-sections, flood hazard boundaries, BFEs, flow, roughness coefficients, manmade structures and other data related to the NFIP.</eaover>
      <eadetcit>Appendix N of FEMA Guidelines and Specifications for FEMA Flood Hazard Mapping Partners contains a detailed description of the data themes and references to other relevant information.</eadetcit>
