WebJun 18, 2024 · The first hydrograph peak was composed of a water-dominant flow, mainly from the upper water-laid layer at the tailings pond, whereas the second contained a high tailing load in a high viscosity flow. The mudflow flood hydrograph is divided into three stages: Stage (A), rapid increase; Stage (B), rapid reduction; Stage (C), slow reduction. 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. WebFlow which bypasses an inlet on grade and is carried in the street or channel to the next inlet downgrade. ... The lag time is defined as the time from the centroid of the excess rainfall to the peak of the runoff hydrograph. Peak Discharge .
