Field Study of the Talgar River Basin within the Framework of a Scientific Project

In 2025, within the framework of a scientific project AP27511595 “Development of a Regional Geoinformation System for Monitoring and Assessing the Outburst Hazard of Moraine-Glacial Lakes in the Eastern Part of the Ile Alatau, a comprehensive field study of the Talgar River basin was carried out to obtain high-precision data for debris flow modeling.

The main activities included ground-based surveying of the river channel and the use of unmanned aerial vehicles (UAVs) to conduct aerial photography and generate an orthophotoplan. Based on the collected materials, a high-resolution digital elevation model (DEM) will be developed, which is considered a key outcome of the 2025 research stage.

The creation of the DEM is essential for assessing debris flow hazards and for modeling possible scenarios of a moraine lake outburst and subsequent debris flow along the Talgar River channel. The use of the developed model will enable detailed visualization of debris flow propagation, identification of potential impact zones, and assessment of risks to both natural and anthropogenic objects. Thus, the conducted research provides a scientific foundation for forecasting debris flow processes and developing measures to mitigate their hazardous consequences in the Talgar River basin.
