  1. 1. V-Shaped Valley
  2. 2. Define <ul><li>V-Shaped Valley </li></ul><ul><ul><li>A valley having a cross-sectional profile in the form of the letter V, commonly produced by stream erosion. Also known as V valley. </li></ul></ul>
  3. 3. The satellite image of the V-Shaped valley <ul><li>the river </li></ul><ul><li>v-shaped valley </li></ul>
  4. 4. The side view of the V-Shaped Valley <ul><li>V-shaped valley: </li></ul><ul><li>Steep gradient </li></ul><ul><li>river </li></ul>
  5. 5. Side view of V-shaped valleys <ul><li>v -shaped valleys </li></ul>
  6. 6. Impacts on Human Advantages (Opportunities) Disadvantages (limitations) Blocks wind: cooler temperature in daytime and warmer temperature at night Danger of avalanches and landslides Easy access to the water Difficult accessibility in terms of transportation Rich resources
  7. 7. Meanders – the middle course of River Cuckmere
  8. 8. Define <ul><li>Meander </li></ul><ul><ul><li>A meander in general is a bend in a sinuous watercourse. A meander is formed when the moving water in a river erodes the outer banks and widens </li></ul></ul>
  9. 9. Meanders <ul><li>meanders </li></ul><ul><li>: curved river </li></ul><ul><li>flood plain </li></ul>
  10. 10. Meanders
  11. 11. Impacts on Human Advantages (Opportunities) Disadvantages (limitations) Create fertile soil on the floodplains Dislocation of the land (agricultural land) transportation Floods occur easily trade
  12. 12. Levees on Mississippi River <ul><li>map </li></ul>
  13. 13. Define <ul><li>Levees </li></ul><ul><ul><li>A levee, levée, dike (or dyke), embankment, floodbank or stopbank is a natural or artificial slope or wall to regulate water levels </li></ul></ul>
  14. 14. Levees <ul><li>levees </li></ul>
  15. 15. The side view of the Levees <ul><li>levees: </li></ul><ul><li>containing accumulated sands and rocks </li></ul>River surface
  16. 16. Impacts on Human Advantages (Opportunities) Disadvantages (limitations) Natural protection against disaster such as floods Stops the water to flow back to the river after flooding Stops sea water to reclaim the land Create fertile land after flooding transportation trade
  17. 17. Define <ul><li>Waterfall </li></ul><ul><ul><li>A vertical stream of water that occurs where a river or stream falls over the edge of a steep place </li></ul></ul><ul><ul><ul><li>E.g Yosemite Waterfall </li></ul></ul></ul>
  18. 18. Yosemite Waterfall Plunge Pool Hard rock Soft rock
  19. 20. Map
  20. 21. Satellite
  21. 22. Impacts on Human Advantages (Opportunities) Disadvantages (limitations) Tourism/recreation Dangerous Provides freshwater Floods Source of Energy (watermills and hydroelectric plants Provided food and transportation
  22. 23. Define <ul><li>Deltas </li></ul><ul><ul><li>a landform that is created at the mouth of a river where that river flows into an ocean, sea, estuary, lake, reservoir, flat arid area, or another river. Deltas are formed from the deposition of the sediment carried by the river as the flow leaves the mouth of the river. </li></ul></ul><ul><ul><ul><li>E.g. Nile River Delta </li></ul></ul></ul>
  23. 24. Nile River Delta
  24. 25. Map
  25. 27. Satellite View
  26. 28. Impacts on Human Advantages (Opportunities) Disadvantages (limitations) Tourism/Development role economic obstacles Provides freshwater Floods Source of Energy Provided food and transportation Farming
  27. 29. Define <ul><li>Braided channels </li></ul><ul><ul><li>Braided channels” means the intertwined branches or secondary channels of a river or stream and characterized by the separation and rejoining. </li></ul></ul><ul><ul><ul><li>E.g. The Waimakariri River in New Zealand </li></ul></ul></ul>
  28. 30. Waimakariri River
  29. 31. Map
  30. 33. Map
  31. 34. Satellite View
  32. 35. Impacts on Human Advantages (Opportunities) Disadvantages (limitations) Tourism/Development role Floods Provides freshwater Source of Energy Provided food and transportation Fishing – Best Fishing
  33. 36. Rapids- by East Lendings ( County Durham, Great Britain ) Relatively steep gradient-causes/increases turbulence and velocity of water Rock steps along the shallower side of the rapid
  34. 37. Topographic map of the location Rapids by East Lendings
  35. 38. Define <ul><li>Rapid </li></ul><ul><ul><li>a part of a riverbed where the water moves very fast, usually over rocks or around boulders </li></ul></ul>
  36. 39. The satellite image of the rapid rapids
  37. 40. Impacts on Humans Advantages (Opportunities) Disadvantages (limitations) Good for canoeists Rocky banks -dangerous for canoeists Where it has rich agricultural area –it is a major processor and distributor of farm products Fast river flow- Dangerous especially for other water activities eg. Crossing rivers/fishing
  38. 41. Floodplains-River Tay and its floodplain (Dalmarnock, UK) area of land around a river channel which is formed during times of flood
  39. 42. Define <ul><li>Floodplains </li></ul><ul><ul><li>an area of low-lying land across which a river flows that is covered with sediment as a result of frequent flooding </li></ul></ul>
  40. 43. Topographic map of the floodplains floodplain Rail tracks channel
  41. 44. The satellite image of the flood plain
  42. 45. Impacts on Humans Impacts on Humans Advantages (Opportunities) Disadvantages (limitations) water is most available the richness of the alluvial soil of floodplains are severely offset by frequent floods brought on by cyclones and annual monsoon rains very fertile for farming causes severe economic disruption and loss of human life in this densely-populated region. represent cheap sources of transportation, and are often where railroads are located any alteration of the watershed upstream can potentially affect the ability of the watershed to handle water potentially affects the levels of the periodic floods
