N2 - The free overfall can be used as a simple and accurate device for flow measurement in
open channels. In the past, the solution to this problem was found mainly through simplified
theoretical expressions or on the basis of experimental data. In this paper, using the meshless
smoothed particle hydrodynamics (SPH) method, the free overfall in open channels with even and
uneven bottom is investigated. For the even bottom case, subcritical, critical and supercritical flows
are simulated. For the uneven bottom case, supercritical flows with different Froude numbers are
considered. The free surface profiles are predicted and compared with theoretical and experimental
solutions in literature and good agreements are obtained.
Keywords: SPH, free overfall, even and uneven bottom, subcritical flow, critical flow,
supercritical flow.
