Q

Infiltration

A

Process of water moving from above ground into the soil
- The infiltration capacity refers to how quickly infiltration occurs
- Grass crops and tree roots create passages for water to flow through from the surface into the soil, therefore increasing the infiltration capacity
If precipitation falls at a greater rate than the infiltration capacity then overland flow will occur-moderate/ fast

Q

Percolation

A

Water moves from the ground or soil into porous rock or rock fractures
- the percolation rate is dependent on the fractures that may be present in the rock and the permeability of the rock
-slow

Q

Throughflow

A

Water moves through the soil into streams or rivers
Speed of flow is dependent on the type of river
-moderate/fast
