2 cards from this section. Quick, good the night before a test.
What does SCS-CN stand for?
Think about the organization involved in this estimation method.
What does antecedent moisture condition refer to?
Focus on the word 'antecedent' which suggests 'before'.
What does the SCS-CN method estimate?
Focus on what the method was developed for.
True or False: The SCS-CN method is only applicable to large water basins.
Recall the context in which this method is utilized.
Analyze a hypothetical small catchment with varying land uses. If urban areas yield a curve number of 90 and forested areas yield a curve number of 55, explain how these differences impact overall runoff estimations.
Consider the characteristics of urban vs rural landscapes.
Choose three regions with different antecedent moisture conditions. Predict how their runoff responses would differ based on the SCS-CN method and explain why.
Remember how soil moisture influences the runoff potential.
