1 Waves Wave speed The speed the disturbance, and wave crests, travel at. Wave speed = Wavelength Period [m/s] [m] [s] Wave speed: Deep water wave When ocean depth is greater than half the wavelength. Direction of wave Restoring: Disturbance: Energy Surface tension Wind Wind waves Gravity waves Long period waves Tsunami Seiche and storm surge Tides Sun and moon Wave frequency (s -1 ) 0.1s 1s 10s 30s 5min 12h 24h Period 0.017m 1m 10m 1000m Wavelength

2 Wave speed The speed the wave crests travel at. Deep water wave Speed dependent on wavelength (or period). gravity Speed (m/s) = P eriod (seconds). 2 Speed (m/s) = 1.56 * wave period (seconds). Longer waves travel faster. Wave speed: Deep water wave The speed the disturbance, and wave crests, travel at. Speed = 1.56 * wave period Longer waves travel faster Brooks/Cole Storms produce waves of many different periods and heights. Wind wave periods can be up to 30 seconds.

3 Wind wave dispersion Wavelength increases as period increases. Longest waves travel fastest away from storm. Swell Longer waves travel faster (C=1.56*Period). They also decay slower. Brooks/Cole Wave speed: Shallow water wave When ocean depth is shallow compared to wavelength (less than 1/20 th of wavelength) Direction of wave

4 Wave speed: Shallow water wave When ocean depth is shallow compared to wavelength (less than 1/20 th of wavelength) Speed dependent on ocean depth. p Speed (m/s) = gravity Water depth Speed (m/s) = 3.1 * square root(depth in meters) Waves travel faster in deeper water. Wave refraction results in waves being more parallel to shore. Wave refraction

5 Wave refraction A shallow water wave s speed is dependent on ocean depth. Wave refraction A shallow water wave s speed is dependent on ocean depth. If part of a wave is in shallower water then it will travel slower. Wave refraction A shallow water wave s speed is dependent on ocean depth. If part of a wave is in shallower water then it will travel slower.

6 Wave reflection Wave reflection 38cd_wavemotion.swf Wave diffraction When waves pass through a small gap, they reform and radiate outwards.

7 Wave groups Deep water wave groups travel at half the speed of individual waves. New waves appear to form behind the wave group. Wave groups matlab movie Wind waves approaching shore Waves touch the bottom. Wave period remains constant, wavelength decreases. Wave speed = and eventually become Shallow water waves, so Wavelength Period (Wavelength = Wave speed * Period) Speed (m/s) = 3.1 * square root(depth in meters)

8 Wind waves approaching shore Waves touch the bottom. Wave period remains constant, wavelength decreases. Friction slows the bottom of the wave. Waves approaching shore Bottom of wave slows even more as the depth shallows, wave crest moves ahead of the base of the wave. Wave breaks when the ratio of wave height to water depth is ~3:4. How waves break depends on the beach slope. Surf prediction North shore swells come from Northern Hemisphere winter storms. South shore swells often come from Southern Ocean storms.

9 Surf prediction Network of ocean buoys measure wave height, period, and direction. Then account for height attenuation and local shoaling effects. hawaiibeachsafety.org Tsunamis Hilo, April 1946 after Alaskan earthquake (NOAA)

10 Tsunamis Tsunamis can be caused by Earthquakes, Landslide, volcanoes, and asteroid impacts. All of these suddenly displace a large amount of water. Have periods of about 20 minutes, and wavelengths of about 200 km. Average ocean depth is 4 km, so always a shallow water water (depth < wavelength/20). Earthquake generation The March earthquake had a displacement of about 20m over an area ~500 km by ~200 km. Open ocean detection In the deep ocean Tsunami waves have small amplitudes, 10 to 50 cm. Combined with their long wavelength, they are hard to detect, enter DART.

11 Why are they dangerous? Because of their long wavelength, the volume of the displacement associated with a tsunami wave is huge. When it shoals that volume piles up. japan.mov

Shallow water wave, D < L/20, speed: c=3.1*sqrt(h); They feel the bottom; They refract. Period remains constant when wave approach the shore. Swim across shore to get out of a rip current. Tsunamis are shallow water waves. They have periods of around 20 minutes. Get out of their path!
