Think about how water soaks into the ground.
True or False: Infiltration capacity increases as the soil becomes saturated.
What happens to a sponge when it’s full of water?
In an experiment, the infiltration capacity of a sand soil was measured at 30 mm/hr and clay soil at 5 mm/hr. If a storm produced 50 mm of rain, how much will be runoff if the storm lasted for 1 hour?
Calculate total rainfall minus total infiltration.
A farmer uses a Double Ring Infiltrometer and measures infiltration rates of 25 mm/hr initially and 10 mm/hr after one hour. Explain the significance of these measurements for irrigation planning.
Think about water absorption rate changes over time.
