Across
  1. 6. the area of land that can be irrigated with a unit volume of water supplied across the base period.
  2. 7. a minor irrigation system similar to weir which is constructed across a small stream to raise the water level on the upstream side
  3. 10. the cross drainage work to be carried when Canal FSl < Natural Drainage bed level
  4. 11. Regime theory is given by .............
  5. 12. an impermeable layer to reducing seepage loss of irrigation water in canal
Down
  1. 1. Theory that says the silt carried by flowing water in a channel is kept in suspension by the vertical component of eddy current only.
  2. 2. the quantity of water in the fields from the channel compared to the amount of water that enters the channel at the beginning is known as Water......... Efficiency
  3. 3. the practice of irrigating land along lines of consistent elevation in order to conserve rainwater and to reduce soil losses from surface erosion.
  4. 4. the cross drainage work to be carried when Canal bed = Natural Drainage bed level
  5. 5. the depth of water required to raise a crop over a unit area across the base period
  6. 8. the maximum water level in river during flood
  7. 9. the water level in Canal
  8. 12. irrigation in which water is not transported by gravity flow but is lifted with pumps or surge pools etc.
