摘要：The reaction of arid regions on global warming and anticipated process of desertification in Eastern Georgia is investigated. The statistical qualities of the Alazani river are presented for the vegetation period (April - September) along with runoff norms for hydrological section serving main irrigation systems. By using their dynamics through years the trands and tendencies of the changes have been identified. The figures are of scientific value and can by used indesigning and economic organizations for calculating water resources. By applying multifactorial model forecasting equations have been worked out for the Alazani water flow for the whole vegetation period as well as for individual quarters. The long-term prognosis allow rational and through planning of water resources utilization. Due to the warming trend, water evaporation will increase and the river flow will decrease, which will ultimately lead to the lack of water supply in irrigation period in summer. For the aim of mitigation of negative consequences of drought, a set of measures is recommended.
