Question 1.
What does the Unit Hydrograph Method estimate?
Show hintHide hint
Think about how we can measure water flow over time.
Question 2.
What does SCS-CN stand for?
Show hintHide hint
It relates to a method for runoff estimation.
3Question 3.
What is the primary purpose of the Unit Hydrograph Method?
- A) To estimate land area
- B) To calculate peak runoff response to rainfall
- C) To determine soil types
Show hintHide hint
Focus on what Hydra involves.
4Question 4.
True or False: The Rational Method is effective for large, rural areas.
- True
- False
Show hintHide hint
Think about its applications and limitations.
Question 5.
Given a watershed area of 150 acres with a runoff coefficient of 0.3 and a storm with an intensity of 2.5 inches per hour, calculate the peak runoff using the Rational Method.
Show hintHide hint
Remember unit conversions!
Question 6.
Analyze the flood response of two different watersheds: one with urban development and a high impervious surface ratio and another with rural terrain. Discuss how the Unit Hydrograph and Rational Method would differ in their estimates.
Show hintHide hint
Think about the characteristics of each type of surface related to runoff.
