      Title: West Virginia Approximate Zone A Re-Study Flood Model Download Packages

  Description:
    Abstract: The files in this download package contain raster digital elevation models (DEM) for Approximate Zone A streams, buffer polygons of stream DEM's, stream HEC-RAS models, and shapefiles of cutlines and county-wide streams, where available, in select West Virginia counties.  The stream DEM's were extracted by AMEC from a countywide subset of the USGS National Elevation Dataset (NED). This download package was compiled by the WVGISTC.

    Purpose: This data package may be useful to surveyors and/or engineers seeking to create local base flood elevations (BFE). BFEs so created may be a valuable contribution to Letters of Map Change (LOMC), including Letters of Map Amendment (LOMA) and Letters of Map Revision (LOMR). Some advanced knowledge, expertise and specialized software applications are required in order to use the included data.

      Process_Description: The planimetric (x, y) spacing of elevation postings within the source DEM is 1/9 arc-second. The DEM data was downloaded from the USGS National Elevation Dataset (NED) seamless server. The data obtained was subsequently mosaicked and reprojected to the project area's State Plane Coordinate System (SPCS) using the North American Datum of 1983 (NAD83). A conversion was performed to convert from units of meters to units of feet. [Source: AMEC]

      Process_Description: For each stream a geodatabase containing the stream centerline, bank stations, flow path locations and cross sections is created and the data is imported into a HECRAS model. Cross-sections were automatically placed and then modified based on the terrain and orthophotos. Digital geo-referenced hydraulic modeling elements in the form of cross sections attributed with water-surface elevations were provided at the countywide level. Elevations are given in the North American Vertical Datum of 1988 (NAVD88), units feet. [Source: AMEC]

      Process_Description: The stream centerlines provided by the county were ortho-rectified and aligned with the contours where orthophotos were inconclusive. Streams were ortho-rectified at a reasonable scale (approximately 1=2000).The stream centerlines were merged to create a countywide stream centerline feature. [Source: AMEC]
