Abstract

The work gives the assessment of the possible cumulative impact of the three water reservoirs of the hydroelectric power plant series present or designed in the river Enguri gorge on the environmental micro-climate. The spatial scales and intensity of the impact of Jvari, Khudon and Nenskra water reservoirs on the air temperature and humidity are identified by using the analytical solution of a two-dimensional stationary mathematical model of turbulent heat exchange and moisture circulation on the background of the horizontal wind given in the surface atmosphere. Assessment of the cumulative effect of the water reservoirs on the environment is made by superpositioningof the analytical solutions gained for each of the water reservoirs, i.e. the values of the impact effects of the three water reservoirs are summed up at every point of space. The possible cumulative impact of the series of water reservoirs on the regimes of wind and atmospheric precipitations is also assessed. The gained results suggest that any significant change in temperature or humidity may occur only in up to 5 km from the water reservoir coastline, in the wind direction. The impact of the series of the water reservoirs on the atmospheric precipitations and wind values is insignificant. Thus, no significant changes in the climate of the region are expected as a result of the cumulative impact of the series of the water reservoirs.
