Abstract

The proportion of water balance components – precipitation, transpiration, evaporation, underground waters and surface runoff – is a determining factor of stabile development of land area. But this proportion can be considerably disturbed and is permanently changing. Certain many-year averages are usually accepted as a stable state. That is why, in the presented work, we have tried to defi ne water balance on symmetry and invariance principles, to express it as a limit state, which would characterize it as a natural principle and enable comparison with the present balance.
