When a particularly large tidal surge from the Atlantic
大西洋上无比巨大的潮汐
get funnelled into the increasingly shallow water of the river,
会涌进当地河流里不得不流入越来越浅的河水里
it turns into a single powerful surging wave.
它就会变成一股力量巨大向上涌动的海浪
A tidal bore.The most surprising thing,
潮水钻孔 最让人惊奇的事物
the most worrying thing, is the speed of that wave.
最让人担忧的是这个浪的速度
This is a pretty fast boat and we're just staying ahead of it.
这艘船很快我们也只能被它紧逼
The bore travels upstream at up to 20 miles per hour.
可以流进内陆蔓延几十公里
It rolls inland for miles, tearing apart the riverbank along the way.
那个浪可一直奔腾着撕裂沿途的一切
This wave will move over 13 million cubic feet of water every minute.
每一分钟会移动400000立方米的水
That's up to 150 times the minimum flow of the Niagara Falls.
最高达到尼亚加拉瀑布水量的150倍
This bore shows just how much energy is created
这个潮涌显示了这个能量是多么强大
by the power of gravity, and released in a tide.
来自重力的能量，通过潮汐释放出来
