他们想到用电脑模拟的方法来实验,而不是在海岸实验。
This is harder than it sounds.
实际做起来要比听起来难很多。
Simulating the way waves behave as they make landfall means taking account of, literally,oceans of data.
要模拟当海浪到大陆地时海浪的运动就意味着要严格地考虑到海洋的信息。
To simplify the problem, the researchers looked at what happens when a computerisedwave encounters a cone-shaped island on a smoothly sloping seabed in front of a straightcyber-coastline with a beach that continues to rise smoothly as it progresses inland.
为了简化问题,在带有海滩的笔直虚拟海岸线可平滑上升的情况下,研究人员观察当模拟的的海浪在平滑的斜海床上与锥形岛屿相遇时,会发生什么。
These approximations allow a computer to cope with the problem, yet are sufficiently similarto many real places for the conclusions drawn from them to, as it were, hold water.
电脑在处理这类问题时,这种近似可以忽略,然而这跟之前认为得减弱海浪的结论已经很相似了.
The team made their virtual islet jut out of the ocean to an altitude of 100 metres, a typicalheight above sea level for such outcrops.
研究组将模拟的岛屿拉高到海平面100米的位置,许多岛屿超出海平面也就是100米。
