West Bouldin Watershed Master Plan, (City of Austin Public Works Project), Austin, Texas:
Project Descriptions: Update the effective model cross-sections for West Bouldin Watershed with recent topography and prepare the comparison with the effective model cross-sections to verify the current conditions of the channel and determine necessary modifications of the channel hydraulic configuration to reduce any possibility of potential flooding.
Services Provided: Use FEMA effective condition geo-referenced GIS shape files for cross sections as reference, create elevation surface from currently existing topographic data, overlay the existing condition cross-section shape file over the effective condition surface, generate cross-section geometry for existing condition using HEC-GeoRAS matching the locations for effective condition, compare the existing Geometry with the effective/City of Austin Geometry in HEC- GeoRAS utilizing comparison tool and customize the comparison plot as needed.
