STWAVE Modeling of the Yahara River / Lake Mendota Outlet

CEE 514 - Coastal Engineering Final Project

Chris Reichle

ABSTRACT

Problems of shoreline erosion and extreme sedimentation have persisted in the Yahara River outlet to Lake Mendota throughout the past decade.  Increased urbanization and the loss of wetlands have generated large sediment loads in the Yahara River, which drains into Lake Mendota.  In 1994, a major channel dredging project was performed in the outlet.  However, shoreline erosion and rapid sedimentation continue to occur at unexpected rates.  Therefore, the sediment transportation phenomena in the outlet must be uncovered before any long-term projects will be conducted in the region.  The results of this research will demonstrate how wave refraction and wave breaking contribute to the shoreline erosion and rapid accumulation of sediments in certain regions of the Yahara River outlet to Lake Mendota.
