The Drainage Baisin Hydrological Cycle
- Catchment area where a river system obtains its water.
- The watershed(imagnary line) seperates one basin from another- generally follows a ridge of highland, water will fall either side creation the two seperate basins.
- Open system with inputs and outputs.
INPUTS: - Evaporation-> energy from the sun
-Precipitaion-> rain, snow or sleet
OUTPUTS: - Evaporation and Transporation-> plants
-Water percolating deep into the ground where it can be lost in the system.
STORAGE: - On the surface - glaciers, lakes, rivers, puddles
-Vegetation stores water by interception and plants
-The soil can hold water
- Groundwater is stored in permeable rocks
TRANSFERS AND FLOWS: -Transfers include throughfall, stemflow, infiltration, throughflow and groundwater flow.
