6. Factors Affecting Runoff and Hydrograph Shape

Try these first

1. 1.

   What happens to runoff during high-intensity rainfall?

   Hint

   Consider how the ground can absorb water.

2. 2.

   Name a type of soil that has high runoff.

   Hint

   Think about how water moves through different types of soil.

3. 3.

   What type of soil is expected to have high runoff?

   • Clay
   • Sandy
   • Loamy

   Hint

   Think about how easily water flows through different soil types.

4. 4.

   True or False: Vegetation can help reduce runoff.

   • True
   • False

   Hint

   Consider the role of plants in absorbing water.

5. 5.

   Predict how hydrograph shapes would differ in a forested watershed versus an urban watershed after an equal amount of rainfall.

   Hint

   Think about how surfaces differ in absorbing rain.

6. 6.

   Design a water management plan considering all factors that affect runoff in a small urban watershed. Outline potential solutions for mitigating flash floods.

   Hint

   Consider how each factor interacts and influences water flow.
