Across
  1. 1. A landform occurring in the upper course, caused by vertical erosion
  2. 3. Sand grains and small stones bounce along the river bed
  3. 5. Sand and stones in the river scrape the bed and banks, wearing them away
  4. 8. Formed on the side of a meander where there is more deposition
  5. 13. Rock that does not let water through
  6. 16. Rocks and stones knocking together and wearing each other away
  7. 17. The land either side of a river in the lower course that usually gets flooded
  8. 21. A graph used to display a river’s response to a precipitation event
  9. 23. The movement of water from the soil into the ground rock
  10. 24. Rock that lets water seep through
  11. 27. The material that a river deposits
  12. 29. Water returning to the atmosphere from leaves, plants and trees as water vapour
  13. 33. Any form of water falling from the atmosphere, like rain, sleet, snow, hail
  14. 35. When leaves, plants and trees catch rain as it falls, preventing it from reaching the ground
  15. 37. The area drained by a river and its tributaries
  16. 41. Natural embankments built up by the side of the river when it floods
  17. 42. The straightening and deepening of a river, making water move more quickly through that part of the river
  18. 44. Formed on the side of a meander where there is more erosion
  19. 45. The point at which two rivers meet
  20. 46. The movement of water sideways through the soil
  21. 48. When eroded material is dropped by the river
  22. 49. Flood management methods that work with nature, using more natural methods, like afforestation
  23. 51. The movement of water through the rock
  24. 52. Larger stones and rocks are rolled along the river bed
  25. 53. The movement of water over the surface
  26. 54. The material that a river carries
Down
  1. 2. The planting of trees
  2. 4. A smaller river that joins a larger river
  3. 6. The heavier material that a river carries along the bottom
  4. 7. Formed when the old channel of a meander is cut off from the river
  5. 9. A landform in the upper course, formed when a river crosses a band of harder rock
  6. 10. The speed of flow in a river
  7. 11. Raised banks build alongside the river, to make the river deeper to reduce the likelihood of flooding
  8. 12. Water returning to the atmosphere from the ground as water vapour
  9. 14. The end of a river, where it meets the sea, or joins another river
  10. 15. The wearing away of the river bank and bed
  11. 18. The movement of water into the ground
  12. 19. The growth in towns and cities, as more people move there
  13. 20. The boundary marking the edge of a drainage basin, usually hills or mountains
  14. 22. A large wall built to control a river’s flow, forming a reservoir behind
  15. 25. A large, deep mouth of a river as it meets the sea, especially useful for ports and shipping
  16. 26. The volume of water flowing past a point in the river in one second
  17. 28. A bend in the river
  18. 30. The movement of eroded material by the river
  19. 31. The cutting down and removal of trees
  20. 32. Water vapour changing back into water droplets, forming clouds
  21. 34. Water is forced into cracks in the bank, which over time breaks up the bank
  22. 36. Alternate hills that stick out like the teeth of a zip in the river’s path
  23. 38. When a river’s load is deposited near the mouth, and builds up over time, like the Nile or Mississippi
  24. 39. Small particles of rock and soil are carried along by the river
  25. 40. Flood management methods that use intensive human intervention, like dams, embankments etc.
  26. 43. Dissolved chemicals and minerals in the water can break up the bed and banks
  27. 47. The football team currently at the top of the English Premier League
  28. 50. The beginning of a river
