Hydraulic Transient Modeling of Tarp Systems

Under the agreement of November 1, 1986, between the Metropolitan Sanitary District of Greater Chicago and the University of Minnesota, the St. Anthony Falls Hydraulic Laboratory of the University conducted mathematical modeling of the recently completed portions of the Tunnel and Reservoir Plan (TARP), both the Mainstream System and the Calumet System of Greater Chicago, for the purpose of establishing optimum operating procedures and additional structures to control hydraulic transient problems. The scope of the work was later extended to include the Des Plaines System and the 13A tunnel when operated independently of the Mainstream System.
