Navigation Mission
• Conduct research regarding the planning, design, operation, management, and maintenance of navigation channels, locks, ports, and waterway systems.
• Provide safe and efficient marine transport, cost effective systems, and environmentally acceptable conditions.
• Employ analytical techniques, numerical models, simulator models, physical models, field investigations, and consultation services.

Inland Hydrodynamics Work Area
Challenges• Inland Traffic Increasing/Capacity
at limit • Need to increase capacity and
reliability • Safer and more efficient lock
approaches • Emergency repairs increasingly
likely • Ice/debris reduce capacity, cause
accidents • Improved fill/empty systems• Reduce construction costs of
new/rehabed locks

Research and Development
Inland Navigation Infrastructure Work Area
•Challenges• Most locks are approaching or have exceeded
their 50-year economic life• Unscheduled failures of steel locks gates,
concrete lock walls, and pumps and motors reduces lock reliability, system efficiency and capacity
• Understand existing condition, relation to strength capacity and remaining service life to effectively plan and schedule repairs, major rehabilitations and replacements

Inland Nav Safety Initiative
• Purpose: – An initiative that will require U.S. Coast Guard
(USCG), USACE, navigation industry and other Federal agency cooperation and collaboration to ensure increased safety, security and reliability of our navigation projects along our inland and intracoastal waterways.
