2.3. Design Discharge Calculation

Try these first

1. 1.

   What is design discharge?

   Hint

   Think about what the term 'discharge' relates to in irrigation.

2. 2.

   Name one type of loss that needs to be considered during discharge calculation.

   Hint

   These losses occur while water is transported.

3. 3.

   What is the primary factor that influences design discharge?

   • Crop types
   • Soil types
   • Climate conditions

   Hint

   Think about what different crops need.

4. 4.

   True or False: Evaporation is the most significant contributor to canal water losses.

   • True
   • False

   Hint

   Consider types of losses discussed.

5. 5.

   A farm covers 10 hectares and requires 15 liters per square meter per day. If the total loss anticipated is 25%, calculate the total design discharge needed.

   Hint

   Ensure you convert hectares to square meters.

6. 6.

   Discuss how seasonal variations can alter irrigation discharge calculations and provide examples.

   Hint

   Consider how weather patterns change throughout the year.
