Suppose rainfall suddenly increases the initial flow rates by 20 cubic feet per second for all rivers. How does this impact the time until flooding?

• The time until flooding decreases.
• The time until flooding is unaffected by rainfall.
• The time until flooding remains the same.
• The time until flooding increases.
