U.S. Army Corps of Engineers Hydrologic and Hydraulic Assessment

Through the Water Resources Development Act of 1974 (PL93-251), the U.S. Army Corps of Engineers (USACE) offers planning assistance to the states (PAS). WREC worked with the USACE to complete a hydrologicl and hydraulic study of issues pertaining to the development of the urban corridor master plan under phase I of this project. In phases II and III, WREC and the USACE investigated the rural portion of the Wabash River and its major tributaries including Wildcat Creek, Wea Creek, and the Tippecanoe River. Phase I was completed in September 2007 and as of March 2010, phases II and III are in progress.

Phase I: The USACE used the best available digital elevation information to determine the 1, 2, 5, 10, 25, 50, 100, and 500-year frequency floods for the Wabash River from River Mile (RM) 307 to RM 321 or from Fort Ouiantenon to Prophetstown State Park. Additional assessments of the impact of low-flow dams, the need for bank stabilization, and effects of removal bays or lakes and correcting Combined Sewer Overflow (CSO) issues were included as part of the project. The final report is available here.
