15.6.2.1. Double Mass Curve Analysis

Try these first

1. 1.

   What is a Double Mass Curve?

   Hint

   Think about how we visualize data over time.

2. 2.

   Why is data consistency important in hydrology?

   Hint

   Consider how water is managed and its impacts.

3. 3.

   What does a straight line in a Double Mass Curve indicate?

   • Data consistency
   • Data inconsistency
   • Missing data

   Hint

   Consider what it means when things match perfectly.

4. 4.

   True or False: The Double Mass Curve can be used for only one dataset.

   • True
   • False

   Hint

   What does 'double' imply in this context?

5. 5.

   Analyze the rainfall data from two gauges over the monsoon season. Create a Double Mass Curve and discuss potential discrepancies.

   Hint

   Look closely for where the two datasets diverge.

6. 6.

   Propose a methodology for ensuring consistency in rainfall datasets before using them in hydrological planning.

   Hint

   Consider what actions ensure data reliability from start to finish.
