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