External water exchange of the lakes of the territory of insufficient humidification
The external water exchange of north Kazakhstan lakes is estimated. 170 water objects are reviewed. Three sets of the external water exchange indices were calculated: calculation using inflow, calculation using inflow and precipitation, calculation using evaporation. Climatic and morphometric indices of water exchange were calculated for the estimation of the share of active and adaptive factors in formation of the external water exchange. Territory zoning using external water exchange indices was made.
