The 2013 Inland Navigation course took a look at locks and dams and, in particular, the issues of aging infrastructure related to them. Inland navigation focuses on the measurement of economic losses from traffic delays due to lock and dam failure whereas flood risk management studies tend to evaluate loss of life and assets at risk from flooding due to dam failure. In both situations, asset management, operations and maintenance, and the role of planners are important. The class participated in a field trip to the Marmet Locks and Dam, built in 1933. It was a great example of a project that has exceeded its design life, which has the potential to have a large negative impact on navigation should the structure fail.
