Water Budget Parameters [Flux Terms] P = E + T + Q + GW r - GW d

Water Budget Parameters [Flux Terms] P = E + T + Q + GW r - GW d GW r - GW d = 0 at steady state. P = precipitation E = evaporation T = transpiration Q = surface runoff GW r = groundwater recharge GW d = groundwater discharge E + T often "lumped" as ET
