“CLIMATE-RUNOFF” MODEL
Climatic factors (precipitation, temperature)
Underlying surface (swamps, lakes, cavern water, soil)
Annual natural runoff
Lifeconditioned runoff
Water management actions(irrigation, drainage, swift
transference of water, creation of artificial reservoirs)

PRINCIPAL QUESTIONS
How do you estimate natural water resources?
How do you take into account climatic changes in runoff calculations?
How do you estimate runoff changes as a result of simultaneous global warning
and water management transformation?

Hydrological system under anthropogenic influence
Hydrological system under anthropogenic influence can be described by means of the classical mechanics master equation of the Liuville type as follows:
dY—+ L(Λ,Y)= εdtY(t) = Y(t0)-S L(Λ,Y)dt +S ε dt У (t0 ) - natural flow; Y(t ) - anthropogenic flow; ε - external effect caused global warming; L - operator of life-conditioned influence describing flow changes under water-management transformations (irrigation, additional evaporation from water surface of artificial water reservoirs, regenerated flow).

Response Functions for Long Time Average of Annual Response Functions for Long Time Average of Annual Lifeconditioned Runoff of CatchmentsLifeconditioned Runoff of Catchments
The figure shows response functions for long time average (norm) of annual lifeconditioned runoff of catchments, situated on the Crimea pensula’s plain. Ordinates of these dependences are coefficients, characterizing changes to the norms of runoff under conditions of additional inflow from agricultural areas, irrigated by water of North Crimean Canal. The figure illustrates increasing norms of lifeconditioned runoff with growing areas of irrigation . If The anthropogenic effect depends on the level of optimal moistening of soil. At present time small rivers of the Crimean pensula’s plain are drainage canals. The red line shows the level of essential changes of runoff norms equal to 10%.
