Аннотация: Kazakhstan belongs to countries with limited surface water resources, the total indicators of household effluent of 50% probability level amount to 91.3 km3 per year [1]. The region under study falls within the Yesil (Yesil river) and Nura-Sarysu (Nura river) water-management basins. 3.1% of the river runoff of the country is formed here [1]. The main rivers of these basins – Yesil (the old name - Ishim) and Nura were studied. The annual flow of these rivers in a high-water year can exceed the flow of low-water year more than a hundred times [2]. At the same time, these figures do not take into account theirretrievable loss of water resources associated with an increase in evaporation from the water surface due to anthropogenic transformation of the beds and floodplain terraces of the rivers. The article assesses the changes in main morphological elements of the river valleys, associated with the development of the fields of building materials. The loss is estimated based on the analysis of different-time data of remote sensing and hydrological calculations with determining the evaporation discharge from the water surface. Keywords: water resources, anthropogenic transformation, evaporation from an open water surface, irretrievable losses of water, water consumption, suburban area, Yesil river, Nura river.
