2 cards from this section. Quick, good the night before a test.
Define rainfall intensity.
Think about how much rain falls in an hour.
What happens when rainfall intensity exceeds infiltration capacity?
Consider what happens to water when it can’t soak in.
What is rainfall intensity measured in?
Think about how we measure precipitation.
True or False: Runoff occurs when infiltration capacity is greater than rainfall intensity.
Consider the definitions we discussed.
Consider a city experiencing heavy rainfall with an intensity of 80 mm/hr, while its soil has an infiltration capacity of 25 mm/hr. Calculate the runoff rate and discuss potential impacts on urban infrastructure.
Subtract the infiltration capacity from the rainfall intensity to find the excess.
Propose a comprehensive strategy for a community facing frequent urban flooding due to rainfall intensity that exceeds infiltration capacity. Include measures for both immediate response and long-term solutions.
Consider the layers of mitigation: quick fixes vs. permanent changes.
