  1. River Mapping for Endangered Species Habitat and Streambank Erosion Assessment: Case Studies at Fort Benning and Camp AtterburyPaul Ayers, Kelsey Hensley, Ken Swinson, Bryan McConkey, Brett ConnellBiosystems Engineering, University of TennesseeHeidi Howard, ERDC - CERLMike Peterkin, Natural Resources CoordinatorCamp Atterbury JMTCHugh Westbury, Watershed Program Manager, Fort Benning

  2. Objectives • Use canoe and kayak-mounted underwater videomapping system • Develop aquatic habitat maps for the Driftwood River (20 miles) • Develop optimum habitat maps for Rayed Bean (Villosa fabalis) mussel - PWTB 200-1-114 • Snorkel and sneak peek mapping • Streambank mapping (erosion) - Legacy • Ocean/coral reef aquatic habitat maps

  3. WATERPROOF CASE SONAR TRANSDUCER LASERS VIDEO CAMERAS

  4. GPS Audio Encoder Audio output (GPS output) Audio Input (GPS input) Splash Cam Video input Geo-referenced Image Recording GPS NMEA Data (ASCII) DVD Recorder

  5. Canoeing with Drop-down Camera

  6. Georeferenced Above Water Image

  7. GIS Attributes Defined • GPS Position • Depth • Width • Substrate • River Characteristic • Embeddedness • Streambank Erosion (bank height, bank angle, riparian diversity, river sinuosity)

  8. Modified Wentworth Scale

  9. Using underwater lasers to determine Substrate scale (dot spacing is 7.75 inches)

  10. Substrate Classification

  11. Some Substrate Types Sand Cobble Small Gravel Small Boulder Large Boulder Bedrock

  12. RiverSurfaceCharacteristics Run Pool Riffle

  13. Driftwood River River Characteristics 20 mile 38,503 Sample Points

  14. Driftwood River Thalweg Depth 20 mile 38,053 Sample Points

  15. Driftwood River Substrate 20 mile 38,053 Sample Points

  16. Species at Risk Habitat Maps • Rayed Bean (Villosa fabalis) mussel • Develop Optimum Habitat Criteria

  17. Rayed Bean (Villosa fabalis) Habitat Criteria • primarily found in small, shallow rivers • usually about 4 feet in depth or less • in and near riffles/runs • usually found deeply buried in sand and gravel substrates • often in and around aquatic vegetation Search • (Depth <= 4 feet) • River Characteristic = riffle/run • Substrate = sand or gravel

  18. Rayed Bean (Villosa fabalis) 6.7% Optimum Habitat

  19. Obed Wild and Scenic River

  20. Virtual tour capabilities

  21. Summary - River Habitat Videomapping for Aquatic Species at Risk (SAR) Habitat • Cover large reaches (10 miles/day) - continuous • Non-intrusive, no access required • Determine above and below water features • Develop total river habitat suitability index • By mapping every foot of the river, the total amount and location of optimum habitat can be determined (development occupancy model) • Provides permanent historical video database to evaluate changing habitat conditions

  22. Legacy FY 2015 Proposal • Species At-Risk, Species of Concern and Declining Species and Habitat (Natural) Pilot or demonstration efforts of new techniques, methodologies, and management practices, including the implementation of new or innovative monitoring and predictive modeling techniques. • Ken Oristaglio – Fort Picket (Nottoway River) • Roanoke Logperch • Atlantic Pigtoe Others?

  23. Snorkel mapping for Species counts Embedded video recorder and GPS on back strap

  24. Georeferenced manual underwater recording video for observing under rocks

  25. Legacy Project (Year 1) GIS-based streambank mapping to identify areas of erosion potential on rivers/streams within military installations (Camp Atterbury and Fort Benning) Mapping Site-specific Streambank Erosion

  26. Streambank Erosion Videomapping • Determine erodibility and erosivity • Identify areas of restoration needs • Cover large areas (10 miles/day) - continuous • Non-intrusive, no access required • Permanent video database and virtual tour capability • Uses EPA Bank Assessment of Non-point source Consequences of Sediment (BANCS) for annual total streambank erosion prediction • Used to determine sediment TMDL’s.
