2.1. Types of Canal Losses

Try these first

1. 1.

   What is seepage in the context of canal losses?

   Hint

   Think about how water could escape from a canal.

2. 2.

   What does evaporation refer to?

   Hint

   Consider the hot sun and water.

3. 3.

   What is the largest contributor to canal losses?

   • Evaporation
   • Transpiration
   • Seepage

   Hint

   Think of what leaks out through the canal walls.

4. 4.

   True or False: Operational losses occur due to the maintenance of canals.

   • True
   • False

   Hint

   Poor management leads to more losses.

5. 5.

   A canal is losing water due to seepage and evaporation. Calculate the total loss if seepage is 30% of the flow, and evaporation accounts for another 5%. What is the total percentage of water lost?

   Hint

   Just add the two percentages together.

6. 6.

   You have a canal system with operational losses measured at 10%. If the total discharge is 1000 cubic meters, what is the effective water that reaches the crops after accounting for operational losses?

   Hint

   Calculate 10% and subtract from total.
