“…Solution of these complex models is dif cult, since many parameters are included that may be negligible in operation (Brdys and Ulanicki, 1994). For these reasons, the system model should be obtained using dominant variables to re ect the dynamical behaviour of the plant (Elbelkacemi et al, 2001;Ermolin et al, 2001). Dynamic behaviour of a water supply system can be determined using the active and passive dynamical components such as pumps, pipes and reservoirs (Cembrano et al, 2000;Eker and Kara, 2001b).…”

“…The friction losses in pipelines of such a large water supply system dominate the losses created by valves, at exit and entrance of the reservoirs, in the inner surface on the reservoirs and in the pumps (Douglas et al, 1985). There are several approaches obtained from theoretical considerations and experimental data for friction loss in pipes (Fox, 1977;Ermolin et al, 2001). The total loss in a pipeline can be given as (Eker and Kara, 2002):…”

This paper presents experimental and model-assisted investigation of activities in a water supply system to manage water transfer using some experiments that are performed on the real system, and simulations obtained from a nonlinear model of the system. The physical system consists of a sequence of pumping stations that deliver water through pipelines to intermediate storage reservoirs. The nonlinear model is obtained using dominant system variables that represent active and passive dynamical elements. The hydraulic models include nonlinear coupling between flow rates and reservoir heads. Validation of the nonlinear model is accomplished through comparing with system observations and using data validation and face validity approaches. The results demonstrate the dynamical behaviour of the system regarding flow stability, water heads in the reservoirs, head losses and measure of the friction at different sections of the water supply system.
