Hey there, would someone please be able to explain to me the realtionship between saturated soils and outflow rate?

Hey there,

would someone please be able to explain to me the realtionship between saturated soils and outflow rate? Is the rate of water flow faster when soil is not saturated as water is more easily able to travel through the soil? and in turn would saturated soils take longer for water to travel through? Please explain!
