Question
When waves generated by tsunamis approach shore, the height of the waves generally increases. Understanding the factors that contribute to this increase can aid in controlling potential damage to areas at risk.
Green's law tells how water depth affects the height of a tsunami wave. If a tsunami wave has height H at an ocean depth D, and the wave travels to a location of water depth d, then the new height h of the wave is given by h = HR 0.25, where R is the water depth ratio
given by R = D/d. (Round your answers to two decimal places.)
(a) Calculate the height of a tsunami wave in water 20 feet deep if its height is 5 feet at its point of origin in water 10,000 feet deep.
ft
(b) If water depth decreases by a third, the depth ratio R is increased by 1.5. How is the height of the tsunami wave affected?
The new height of a tsunami wave is
times the height before R is increased by 1.5.
