In the present study, a widely used mathematical method for unsteady flows in closed conduits such as pipes and/or tunnels, called the Method of Characteristics (M. O. C.) was employed to perform water-hammer analysis of the pipelines extending from the Camlidere dam to the Ivedik water treatment plant in Ankara. Both of the existing parallel pipe lines, are formed by various steel pipes, reinforced concrete pipes and concrete lined tunnels connected in series and having different material characteristics in roughness, diameters and lengths. To take into account all of these various characteristics of the pipelines, the unsteady flow equations consisting of the interpolation feature were used when employing the M.O.C. An algorithm was developed which was incorporated into an existing computer model, written in FORTAN language. By way of this program, the numerical simulations of water hammer problem under desired scenarios were performed. As a result, closure durations were recommended for the pipe fracture safety devices planned to be located at certain places and to be put into operation automatically in case of emergency, without causing excessive pressures in the lines.
