3.2. Estimation of Losses

Try these first

1. 1.

   What is seepage loss?

   Hint

   Think about where water might escape from the canal.

2. 2.

   Why are evaporation losses significant?

   Hint

   Consider the factors that might increase evaporation.

3. 3.

   Which type of loss occurs due to water seeping through the canal bed?

   • A) Absorption
   • B) Seepage
   • C) Transpiration

   Hint

   Focus on which term indicates 'leakage' from the canal.

4. 4.

   True or False: Evaporation losses are not influenced by wind speed.

   • True
   • False

   Hint

   Think about how wind affects water temperature.

5. 5.

   Calculate the total seepage loss for a canal that is 15 km long, has a bed width of 4 m, depth of 1.5 m, and a K value of 2.0.

   Hint

   Break down the formula and substitute the numbers step by step.

6. 6.

   Propose a management strategy for reducing evaporation losses in a canal situated in a hot, windy region.

   Hint

   Consider both natural and artificial methods to reduce exposure.
