Water budget 
The water budget is the annual balance between precipitation, evapotranspiration and runoff.
They can be useful at both glacial and local scales
Water balance equation 
P = Q + E +/- S
P is precipitation, E is evapotranspiration, Q is runoff and S represents changes in storage over a period of time, usually one year
Potential evapotranspiration (PE) 
An estimate of the amount of water lost through evaporation and transpiration in any given period, depending on temperature and air humidity.
Water balance
A) Soil moisture recharge
B) Soil moisture surplus
C) Soil moisture utilisation
D) Soil moisture deficit
E) Soil moisture recharge
