Our transcription: High tides can create tremendous havoc, especially if they're combined with violent storms.

This is what happened in 1970 in Bangladesh when a cyclone combined with a spring tide flooded the delta of the Ganges River, drowning a quarter of a million people.

But such tidal disasters are rare.

Most of the time the twice daily ebb and flow of tides only brings about small brief changes in the water level.
