high water best months to go

From about 12 m³/s in the lowest month to 113 m³/s in the highest. Best months to go, with plenty of water and pleasant days: from August to November.

Estimate: the timing comes from rain, snowmelt and evaporation (NASA POWER, 1991–2020); the amounts from the river model of HydroATLAS (WaterGAP, 1971–2000). Dams upstream can change the real flow.

Pongour Waterfall is a waterfall in Vietnam. The water falls 40 m over a front 100 m wide.

20 MW

About 51 m³/s falling 40 m: the power of the water as it drops.

  • as much as 6.7 large wind turbines
  • enough to power about 5,000 homes, if it were all turned into electricity

Power of falling water = density × gravity × flow × height. Average flow and height as shown above; an estimate.
