Presentation Transcript

  1. Some Project Ideas • Literature review of particular subjects – what is new since “Applied Hydrology” was originally published? • What are the key papers in this field since 1988? • Flood hydrology modeling and flood mapping • Effect of flood control dams in Sanderson, Texas • Unsteady flow modeling using HEC-RAS

  2. NRC Studies on Flood Mapping • Elevation Data for Floodplain Mapping (2007) • http://www.nap.edu/catalog.php?record_id=11829 • Examines elevation and image information supporting flood mapping and recommends coast to coast LIDAR for the nation • Mapping the Zone: Improving Flood Map Accuracy • http://www.nap.edu/catalog.php?record_id=12573 • Case studies of the uncertainty in hydrology, hydraulics and terrain data on flood map accuracy

  3. Adjusted goal: 92% of population and 65% of land area will have a modernized map 21% of population has maps meeting the floodplain boundary standard and engineering study standard

  4. Map Modernization in Texas Source: FEMA Region VI RMC

  5. Sanderson, Texas County Seat of Terrell County

  6. Flood Mapping in Sanderson • There is an existing paper flood map • There was a severe flood in Sanderson on June 11, 1967 in which 28 people died • The USDA Soil Conservation Service built several flood control dams upstream of Sanderson during the 1980’s • Sanderson needs a Digital Flood Insurance Rate Map to reflect the existence of these flood control dams http://www.sandersonchamberofcommerce.info/history/
