AS Geography - River terms

Stores
1. Interception: Prevention of rain reaching the ground by plants
2. Surface Storage: Total volume of water held on the earth's surface in lakes, ponds and puddles
3. Soil Storage: Water held within the soil
4. Groundwater Storage: Storage of water underground in permeable rock strata (aquifer)
5. Vegetation Storage: Water being held within or on vegetation
6. Channel Storage: Water being held within a river
Transfers
1. Leaf Drip: The precipitation that falls to the ground from leaves after interception
2. Infiltration: Gravity flow of water within the soil
3. Through Fall: Precipitation falling through the plant canopy
4. Percolation: Downward movement of water into the soil
5. Surface Runoff: Movement of water over the surface - usually when the ground is frozen or saturated
6. Through Flow: Movement of water downslope within soil layer
7. Base Flow: The deeper movement of water through the underlying rock
8. Stem flow: Rainfall reaching the ground by daring down stems of vegetation
Inputs
1. Precipitation: Any moisture reaching the earth's suface
Outputs
1. Evapotranspiration: The loss of water from a drainage basin into the atmosphere from vegetation
2. River runoff: Water running within a river until it reaches the sea
