CLIMATE CHANGE AND THE MOUNTAIN RIVER

Climate change inevitably leads to changes in river flow characteristics. Rising surface air temperature leads to melting of glaciers. Changes in precipitation patterns lead to changes in river runoff. Snow falling on the territory of the river basin in winter determines the magnitude of river floods. Rainfall briefly raises the water level in rivers. Downpours lead to the occurrence of floods. The constituents of river runoff - melted snow and glacier - are determined by precipitation regime and air temperature. Based on the mathematical model of river runoff formation, factor analysis of hydrological and meteorological series is carried out, on the basis of which the parameters of runoff and water resources formation are determined.
