GEOMORPHOLOGICAL ANALYSIS OF RIVER SYSTEMS IN THE SAURAN DISTRICT UNDER THE ARID CLIMATE CONDITIONS

https://doi.org/10.48498/minmag.2025.243.7.001

This study investigates the geomorphological features of river systems in the Sauran District of Southern Kazakhstan, located in an arid climate zone. Using remote sensing data (Landsat, Sentinel), GIS analysis, and field observations (2020–2024), the research assesses erosion dynamics, sedimentation, and seasonal hydrology of 11 small rivers. Results indicate increased channel instability due to temperature rise (+2.1 °C since 2000) and reduced precipitation (-60 to -80 mm annually). Seasonal flow reduction, rising salinity, and anthropogenic impact (dams, irrigation, urban growth) have led to degradation of natural channels. The study offers valuable insight into the effects of aridification on ephemeral river systems and supports regional planning.
