This interference may be: They have very long periods and very large heights. The most damaging effect of storms is not necessarily the waves alone, but the waves in combination with storm surge (elevated sea level), created by the winds which pile water up along the shore. lectures | Bending of the wave crest as waves enter shallow water. [ home port | The crests build up and the troughs build down. Waves affect water to a depth equal to or less than one-half their wavelength. In a desert region, what is the absolute limit to the water budget? Standing Waves Waves Entering Shallow Water This leads to wave refraction and waves collapse forming surf (breakers). Rogue Waves?

Internal waves which occur underwater and move along pycnoclines. Other Types of Progressive Waves Destructive wave interference occurs when the crest of one wave coincides with the trough of another wave resulting in a cancellation. A. it evaporates Water depths are less than 1/20 the wave length.

Other Types of Progressive Waves lectures | Standing waves (seiches) do not move horizontally. The stream would lose energy and drop its sediment forming a delta. Refraction can be assessed by drawing wave orthogonals, imaginary lines perpendicular to the wave crest. - Wave form [ home port | cracks, possibly with some vertical displacement, occur upslope, What are some clues that a proposed home site may be susceptible to landslide activity? http://dusk.geo.orst.edu/oceans/waves.html, Swell - more regular waves beyond area of generation Standing waves (seiches) do not move horizontally. The result is amplification of the wave size which can lead to flooding. Waves originate in the fetch area. This interference may be: Wave energy is defocused where the lines diverge.

When a wave breaks at a more acute (steep) angle on a beach, encounters a steeper beach slope, or is very It is the energy of the wave, not its mass that is in motion. The crests build up and the troughs build down. depending on the slope of the bottom Surfing Video: Condition Black surf | Chapter 7 Summary - Wavelength shortens - Speed decreases What causes tsunamis and breakers to "break" as they approach the shore? - Height increases It is due to: Internal waves which occur underwater and move along pycnoclines. Tsunamis which are seismic sea waves. Wave energy is defocused where the lines diverge. Destructive Waves (Figure 7-6c) The size of surface waves depends on the speed and duration of the wind, and the fetch. Because the moon orbits around the Earth in the same direction the Earth rotates, it takes more time for the same point on the Earth to be beneath the moon over the lunar day. Motion of Water Particles Beneath Waves (Figure 7-3b) Internal Waves Sudden shifting of the ocean floor due to earthquakes, volcanic eruptions, and submarine slumping. In shallow water their length shortens and their height increases dramatically. Deep Water Waves (Figure 7-4a) Waves Break by Spilling Plunging, or Surging (Figure 7-9) They have very long periods and very large heights. select four, What factors contribute to over-steepening of slopes? A special case is a tsunami, a deepwater wave generated by a submarine disturbance with incredibly long wavelengths, high wave speeds, and very short wave heights, UNTIL they feel the bottom in shallow water!
