ABSTRACT: Research presents assessment of debris/mudflow ravine located to riv. Tetri Aragvi gorge in the territory of Pasanauri district. Above mentioned ravine is directly adjacent to the Natakhtari-Mleta road and poses a threat to its safety functioning. Research presents analysis, and assessment of expected risks of the factors shaping the debris/mudflows of this ravine. In addition, the accumulated material will serve as a basis for developing modern methods for modeling and assessment of landslide and debris/mudflow events. It states that the formation of debris/mudflows is largely determined by the landslide massif at the source area of the ravine and the strong erosion processes taking place in it. Numerical indicators of the stability of this landslide body have been calculated, considering the main factors—the moisture content of the bedrocks and seismic activity. The study is based on fieldwork data conducted in 2023-2024. Based on it, estimated values were obtained that determine the risks of mudflows. The material presented in the paper will be used in the future to develop mudflow preventive measures.
