4 cards from this section. Quick, good the night before a test.
What does SCS stand for in the SCS-CN method?
Look for the origin of the term in the name.
What does the curve number (CN) indicate?
Think about how land use and soil type affect runoff.
What is the main purpose of the SCS-CN method?
Think about what direct runoff means in water resource management.
True or False: The Curve Number (CN) can range from 10 to 100.
Recall the guideline numbers provided in handbooks.
Given a rainfall depth of 70 mm, an initial abstraction estimated at 10 mm, calculate the expected runoff if the Curve Number is 80.
Carefully follow the steps in the SCS-CN calculation.
Discuss the implications of changing land use from agricultural to urban on the Curve Number and consequently the runoff estimation.
Consider how land characteristics directly affect runoff.
