Flows in m³/s (cumecs) with cusecs alongside: 1 m³/s = 35.31 cusecs, 1 lakh cusecs ≈ 2,832 m³/s. The flood wave follows an SCS gamma hydrograph and enters across the full width of the channel. The river is already flowing at its normal flow when the event starts.
The free terrain is a surface model: it includes rooftops and tree tops, which trap rain in hundreds of false puddles. Cleaning keeps rivers and real low ground.
