48.8. IS Code Recommendations

Try these first

1. 1.

   What is the discharge coefficient?

   Hint

   Think about comparing actual and theoretical discharge.

2. 2.

   Why is crest level important?

   Hint

   Consider how water reaches farmers' fields.

3. 3.

   What does the discharge coefficient represent?

   • A measure of water flow rate
   • A calculation tool for outlet height
   • A factor comparing actual discharge to theoretical discharge

   Hint

   Think about how we measure efficiency.

4. 4.

   Is material choice important in outlet construction?

   • True
   • False

   Hint

   Consider how long you want it to last!

5. 5.

   Calculate the discharge coefficient if the actual discharge is 100 cubic meters and the theoretical discharge is 120 cubic meters.

   Hint

   Remember to divide the actual output by the theoretical one.

6. 6.

   Discuss what could happen if the crest level is improperly set too low in terms of irrigation efficiency.

   Hint

   Consider the effects across the fields and how water levels could change.
