2 cards from this section. Quick, good the night before a test.
What is the largest contributor to canal losses?
Think of where water escapes from a canal.
Name one field method for estimating water loss.
This method involves standing water.
What method can be used to estimate canal seepage losses?
Remember the established equations we discussed.
Is evaporation a major contributor to canal losses?
Think about which loss occurs most frequently.
If a canal has a discharge of 10 cumec and loses 30% to seepage and evaporation combined, how much water is effectively delivered to the fields?
Calculate the losses based on the percentage given.
A 200-hectare agricultural land requires 6 mm of water per day. If the estimated losses are 15%, what is the total design discharge needed?
Don't forget to convert the units properly.
