The fluctuation of inlet flow to a water treatment plant makes a serious problem that it can change the outlet flowrate from each process abruptly. Since it takes very short time for the surface wave occurred from the fluctuation of inlet flow to reach the latter processes, it is impossible for operators to cope with that stably. In order to investigate the characteristics of hydraulic behavior for rectangular sedimentation basin in water treatment plant, CFD(Computational Fluid Dynamics) simulation were employed. From the results of both CFD simulations, it was confirmed that time taken for the follow-up processes by the fluctuation in intake well can be estimated by the propagation velocity of surface waves. Also, it takes very short time for the surface wave occurred from the fluctuation of inlet flow to reach the latter processes. In the case of inlet flowerate being increased sharply, local velocity within sedimentation basin appeared as wave pattern and increased due to convection current. Also, it could be observed that vortex made local velocity in the vicinity of bottom rise.
