1.   I stood by the waterfall, almost hypnotised by the roaring water.

2.   ...the roaring waters of Niagara Falls.

3.   Not only was the Blue icy cold, its roaring waters were high from heavy snowfall this past year, meaning its current was approaching warp speed.

4.   The day began promisingly under a glistening sun at the ultimate water park, a manmade venue of roaring waters directed by plastic cylinders and fake boulders.

5.   Roaring waters also damaged floodworks along creek beds and caused rockslides that closed several roads in central mountain areas.

6.   Ropes were strung across downtown intersections to help people across torrents of roaring water.
