Abstract

A model of the water balance of Torey Lakes is proposed. The model is based on the integration of satellite data for 1989–2020 and ground-based observation data for the period of 1965–2018. The analysis of long-term changes in the water level in the lakes revealed its cyclicity. A possible change in the level of Torey Lakes is estimated taking into account the impact of the construction of a hydraulic structure on the transboundary Ul’dza River. Variants of the planned development of water use in the Mongolian part of the catchment area in the form of the water inflow reduction by 10 and 20% are considered. The water balance model is used to demonstrate a possible negative impact of inflow variations on the hydrological regime of the lakes.
