The purpose this paper is to provide an overview of the inland navigation systems analysis procedures which are being used in the Ohio River Division (ORD). The responsibility for system studies in ORD has been assigned to newly formed navigation planning support centers located in the Huntington District and the Louisville District. The Huntington center is responsible for economic system studies, while the Louisville Center is responsible for physical and environmental system studies. A major systems analysis study was recently completed for the Phase I GDM on Replacement of Gallipolis Locks and Dam. Development and application of the systems approach for the Gallipolis study was costly and time consuming. All of the districts in ORD together with the Division office contributed to this effort. However, with a common data base and analytic procedures in each of the four districts, it is now possible to perform system studies throughout the Division much more efficiently. The Gallipolis methodology, tools and data are now being used in navigation system studies at several projects in ORD.
