What does rainfall duration refer to?
Think about the time aspect of rainfall.
Can short-duration rainfall lead to floods?
Consider the intensity of rainfall.
What is rainfall duration?
Consider what measures time in weather events.
True or False: Longer rainfall durations lead to higher potential runoff.
Recall how saturation affects runoff.
You have two rainfall events: one lasting 30 minutes with an intensity of 70 mm/hr, and the other lasting 5 hours with an intensity of 15 mm/hr. Calculate the total rainfall for each event and discuss the potential impacts on runoff.
Consider both rainfall duration and intensity when calculating.
Evaluate the effect of different rainfall durations on a reservoir designed for a maximum inflow of 200 m³/s. If a short heavy rain with high intensity occurs, what measures should be taken to prevent overflow?
Think about emergency planning and spill management.
