Water Balance (Water and Carbon Cycles) 1.1
Cards in this deck (8)
- 1What is the water balance (budget)?Balance between inputs (precipitation) and outputs ( run-off, evapotranspiration, soil and groundwater storage)
- 2When do rivers only occur?Stores are available to release water, direct precipitation or there is overland flow into the river
- 3What is a river's regime?DIscharge levels rising and falling showing an annual pattern
- 4What is the water balance formula?Precipitation (P) = discharge (Q) +evapotransipiration (E) ± changes in storage (S)
- 5What is potential evaporation?AMount of water that could be evaporated or transpired from an area if there was a sufficient water available
- 6What presents the relationship between precipitation and potential evapotranspiration over a year?Soil Moisture Graph
- 7What does each section of the soil moisture graph show?Green- soil moisture recharge
Blue - Soil moisture utilisation
Pink -Soil moisture deflict
Purple - Soil moisture surplus
Blue line - Precipitation
Dashed red line - Potential evapotranspiration - 8aesu
