![]() If water depth decreases by half, the depth ratio R is doubled.Recent Examples on the Web Centennial 5 also has a smaller amount of beach south of the breakwater.Īlex Hulvalchick, Chicago Tribune, 9 Sep. Calculate the height of a tsunami wave in water 25 feet deep if its height is 3 feet at its point of origin in water 15,000 feet deep. 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 = HR0.25, where R is the water depth ratio given by R = D/d. Green’s law tells how water depth affects the height of a tsunami wave. Understanding the factors that contribute to this increase can aid in controlling potential damage to areas at risk. If a channel width is cut in half by a breakwater, what is the effect on wave height? Reference of Exercise 12:Height of Tsunami Waves When waves generated by tsunamis approach shore, the height of the waves generally increases. What is the height of the wave beyond the breakwater? b. Suppose a wave of height 8 feet in a channel of width 5000 feet encounters a breakwater that narrows the channel to 3000 feet. (See Figure 5.28.) If a tsunami wave of height H in a channel of width W encounters a breakwater that narrows the channel to a width w, then the height h of the wave beyond the breakwater is given by h = HR0.5, where R is the width ratio R = w/W. Breakwaters affect wave height by reducing energy. How is the height of the tsunami wave affected?įunctions and Change (4th Edition) Edit edition Solutions for Chapter 5.2 Problem 9E: Tsunami Waves and Breakwaters This is a continuation of Exercise 12. If water depth decreases by half, the depth ratio R is doubled. Calculate the height of a tsunami wave in water 25 feet deep if its height is 3 feet at its point of origin in water 15,000 feet deep.ī. 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.Ī. ![]() When waves generated by tsunamis approach shore, the height of the waves generally increases. If a channel width is cut in half by a breakwater, what is the effect on wave height? What is the height of the wave beyond the breakwater?ī. (See Figure 5.28.) If a tsunami wave of height H in a channel of width W encounters a breakwater that narrows the channel to a width w, then the height h of the wave beyond the breakwater is given by h = HR 0.5, where R is the width ratio R = w/W.Ī.
