Problems of effective use of the water resources of the transboundary rivers in the steppe zone

Abstract

A comparative assessment of indicators of the water supply sufficiency of transboundary basins in the steppe zone is considered in the paper. It was noted that adequate water consumption problems in separate regions of the steppe zone have the maximal topicality due to hydrodynamic aspects and hydroclimatic specifics. We should pay attention to the account of existing water resources in areas with considerable long-term flow variations. Parameters of effective use of water resources were analyzed in the transboundary river-steppe zone within the Russian-Kazakhstan sector. The nonparametric method of multivariate analysis (PATTERN) was used for the first time to estimate the effectiveness of water resources use. As a result, four groups of the regions differed by the level of sufficient water resources use were selected. In conclusion, the topicality of development and realization of intergovernmental programs concerning the problematic use of water resources of the transboundary rivers in the steppe zone was considered.
