5. Hydrograph

Try these first

1. 1.

   What is a hydrograph?

   Hint

   Think about how water flow changes with time.

2. 2.

   What does peak discharge represent in a hydrograph?

   Hint

   Consider the highest point on the graph.

3. 3.

   What does a hydrograph illustrate?

   • Water temperature changes
   • Streamflow over time
   • Soil moisture levels

   Hint

   Think about how rivers behave after rainfall.

4. 4.

   True or False: Peak discharge is always the same as the base flow.

   • True
   • False

   Hint

   Consider the definitions of both terms.

5. 5.

   Analyze a hydrograph provided to determine the impact of a sudden storm on the peak discharge and discuss how land use may have influenced the results.

   Hint

   Consider how surface materials affect water absorption during rainfall.

6. 6.

   Given a set of rainfall data and hydrograph characteristics, predict the shape of the hydrograph and explain your reasoning.

   Hint

   Think about how different rainfall patterns would affect water flow.
