Across
  1. 4. These are generated by large-scale atmospheric systems or storms, characterized by low pressures and strong sustained winds.
  2. 5. Waves are most commonly caused by?
  3. 8. Disturbances in any medium or substance.
  4. 9. Marine waters out to 15 km are under what government jurisdiction?
  5. 11. Constructed perpendicular to the coastline from the shore into the sea to control longshore currents.
  6. 14. The restoring force that allows them to propagate is gravity.
  7. 18. Lowest point of the wave.
  8. 21. Formed when longshore drift travels past a point where the dominant drift direction and shoreline do not veer in the same direction.
  9. 24. How fast the wave travels.
  10. 26. Type of fish that has no market value as human food.
  11. 28. Zone where the land meets the sea.
  12. 30. Group of trees and shrubs that live in the coastal intertidal zone.
  13. 31. Seismic Sea Waves
  14. 32. Generated due to the combined effect of the Earth’s rotation and the gravitational attraction from the Moon and the Sun.
  15. 33. Attached to the land at both the proximal and distal end and are generally widest at the down-drift end.
  16. 36. Number of waves passing a point in a given amount of time.
  17. 37. Process of coastal sediment returning to the visible portion of a beach.
  18. 39. Distance between trough to trough.
Down
  1. 1. coastal management tool used to analyze and describe the different sediment inputs and outputs on the coasts.
  2. 2. Groyne, Sea Wall, Offshore Breakwater
  3. 3. Structure constructed parallel to the coastline that shelters the shore from wave action.
  4. 6. Two rocky barriers which mark the ends of a beach and have a fixed sediment budget, although usually leaky to some extent.
  5. 7. Semi-Hard coast.
  6. 8. Soft coast.
  7. 10. Geological process that consists of the transportation of sediments along a coast.
  8. 12. Structure that is constructed parallel to the shore (in the nearshore zone) and serves as a wave absorber.
  9. 13. Highest point of the wave
  10. 15. Wave that is formed at the boundaries of water masses of different densities and propagates at depth.
  11. 16. Currents that carry sand, sediment, and even people out into deeper waters if they are not careful.
  12. 17. can act as sinks and sources for large amounts of material, which therefore impacts on adjacent parts of the coastline.
  13. 19. Time it takes for two successive crests to pass a given point.
  14. 20. Disturbances or oscillations in electrical and magnetic fields.
  15. 21. Waves crashing onto shore.
  16. 22. Beach Nourishment, Dune Building
  17. 23. Creates a wider beach by artificially increasing the quantity of sediment on a beach
  18. 25. Loss or displacement of land.
  19. 27. Waves receding back into the ocean.
  20. 29. can either be free or fixed and can occupy a hierarchy of scales, from individual rip cells to entire beaches.
  21. 34. Formed when something falls into the ocean and creates a splash.
  22. 35. The restoring force that allows them to propagate is surface tension.
  23. 38. Hard coast.
