Two concerns prompted the development of dynamic methods for flow routings: (a) the safety of the nuclear plants being planned along the Tennessee River in the 1960's and (b) the water quality emphasis in the environment. This process initiated an extensive modeling effort of the TVA reservoir system to reproduce day-to-day operations, known historical events, and backwater profiles established for extremely large floods. For over 20 years the SOCH model has been a reliable tool in solving a wide array of flow propagation problems in the Tennessee Valley and similar basins. A metric version of SOCH is now available and other features will be incorporated as they appear to be needed. The model is presently being used to establish inundation boundaries for the Emergency Action Plans prepared for all TVA dams.
