The initial stage of dam-break flow
WebHowever, in the early stage of dam collapse, the 3D CFD model captured peak flow very well. Dominant displacement is witnessed at two points, a and c at the center line of the dam gate, where the peak flow obtained by Flow 3D near the dam site is equal to about twice the value yielded by SWEs.
