Try these first

1. 1.

   What do mass curves represent?

   Hint

   Think about what cumulative means.

2. 2.

   What is a hyetograph used for?

   Hint

   Consider how much it rains and when.

3. 3.

   What does a mass curve represent?

   • Rainfall intensity
   • Cumulative rainfall
   • Both

   Hint

   Think about what 'mass' in mass curve means.

4. 4.

   True or False: Hyetographs are useful for analyzing storm intensity.

   • True
   • False

   Hint

   What do you measure with intensity?

5. 5.

   Given a set of data points for rainfall over days, create a mass curve and analyze the trends shown. What anomalies do you identify?

   Hint

   Look closely at the linearity of the curve.

6. 6.

   Evaluate the effects of two different rain gauges represented by a double mass curve. What does a divergence from the expected line indicate?

   Hint

   Consider why one dataset may be off from the other.
