Workshop Background • Spate of Accident at Locks – Highwater Jan 2005 • Belleville most notable • Ohio River and Lower Mississippi River • TRB Meeting in Memphis – Craig Philip (Ingram) • Highlights problem • Clausner suggests meeting • Discussions due to the efforts of Industry catalyst Scott Noble – summer/fall • Late Fall – Michael Winkler (ERDC) organizer • HQUSACE (Kidby) critical support • Considerable Interest

  4. Lock Currents WorkshopParticipating Groups • Corps – Navigation Mission • Divisions/Districts • HQ • ERDC • Industry • Coast Guard • NOAA

  5. Workshop Agenda • Tuesday PM • Ship-Tow Simulator (STS) Demonstration – Lynch • Numerical Model Demonstrations – Berger/Stockstill • Outdraft Presentation – Winkler • Break • LRD Navigation Concerns – Morgan and Sneberger • MVD Navigation Concerns – Hannon • Industry Perspective - Noble

  6. Workshop Agenda • Wednesday AM • R&D Overview (Clausner) • DOTS Program (Clarke) • Corps Role (Kidby) • NOAA PORTS System (Bourgerie) • USCG Perspective (CWO Frascella – S8 ) • Break • Lock Currents Discussion • Planning for Future Efforts (Clausner) • Wrap-up (Kidby/Clausner) • Physical Model Tours (Winkler/McCollum)
