- Persistent onshore winds. Waves originate in the fetch area. Period of wind or tides approximate the natural period of oscillation of the basin. Shoreface/nearshore, What happens to the wave train because of wave dispersion? In shallow water, the sea bottom transforms the wave's properties. - Low pressure which leads to a rise in sea level. There are two other notable types of progressive waves. The crests build up and the troughs build down. lectures | Standing waves can be dangerous due to the phenomenon of resonance. Wave Refraction (Figure 7-8a) Standing waves can be dangerous due to the phenomenon of resonance. B. the spaces between the sand grain in a pile of sand F. barrier islands choose three. Think of sloshing in bathtubs and or swinging in swing The orbital motion of water particles beneath the wave. Tsunamis which are seismic sea waves. Geology Chapters 10-12 Flashcards | Quizlet Shore breakers (surf) are collapsing waves. The 2005 La Conchita slide in California and the 2014, Oso landslide in Washington were both deadly landslides in residential areas. Storm Surges The compact was made in a year of high flow and based allocations on specific volumes and did not consider growth/drought. Click here for ANIMATION In shallow water their length shortens and their height increases dramatically. What was the trigger for this landslide? http://dusk.geo.orst.edu/oceans/waves.html, - Constructive Internal waves which occur underwater and move along pycnoclines. Breaking Waves - National Oceanic and Atmospheric All the statements about Western boundary currents are true, except what? Resonance In shallow water their length shortens and their height increases dramatically. _____________________ causes surface currents, _______________ causes deep currents. C. tombolo There are two other notable types of progressive waves. Period of wind or tides approximate the natural period of oscillation of the basin. All following actions can help mitigate the risk of mass wasting EXCEPT: building a house on top of a cliff to compress the material beneath it, When a landslide damn a river the resulting flooding can be deadly, Which of the following forces are NOT involved in a mass sliding down a slope, The shape of the water molecule is unique with two hydrogen ions bonded to the side of the oxygen ion. email prof. ] http://dusk.geo.orst.edu/oceans/waves.html, - Persistent onshore winds. What important function do surface currents provide to the land? 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! Click here for ANIMATION C. talus blocks Seas, swell, and surf are progressive waves. Think of sloshing in bathtubs and or swinging in swing Materials on a slope tend to move downslope when the _____ force exceeds the _____ force. This leads to wave refraction and waves collapse forming surf (breakers). Standing waves (seiches) do not move horizontally. Progressive Waves - Fetch (distance over which wind blows) Standing waves (seiches) do not move horizontally. Node = Fixed Point, Antinode = maximum displacement (Figure 7-11) Destructive wave interference occurs when the crest of one wave coincides with the trough of another wave resulting in a cancellation. Internal waves which occur underwater and move along pycnoclines. Wave energy is defocused where the lines diverge. depending on the slope of the bottom This area is characterized by a "confused" sea state with extensive wave interference. As waves enter shallow water: If you are considering a home site, what is one pretty sure evidence of possible landslides affecting the property? - Height increases Waves Entering Shallow Water Standing waves can be dangerous due to the phenomenon of resonance. The result is amplification of the wave size which can lead to flooding. email prof. ] 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! lectures | Two basic motions associated with an ocean wave: They are stationary and Resonance Waves are disturbances that are generated on or beneath the sea surface. As waves enter shallow water their wavelength shortens and their height increases. Deep Water Waves (Figure 7-4a) Interaction with the sea bottom. Wave height/wave length. 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. Which of these features is found on a submergent coast, with a relative rising sea level? - Persistent onshore winds. It is the energy of the wave, not its mass that is in motion. This area is characterized by a "confused" sea state with extensive wave interference. Wave Motion with Depth (Figure 7-3a) - Wave form 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! The 1959 Madison Canyon landslide killed 28 people near Hebgen Lake.
