ROUTE SURVEY OF MUDFLOW MANIFESTATIONS IN THE MAMISON GORGE

In order to determine the areas prone to mudflows, a survey of the adjacent territories of the Kozydon and Zemegondon rivers (Republic of North Ossetia-Alania) was carried out. An assessment of the size and volume of previous mudflows was fulfilled, an assessment of the geological conditions of the territory was given, taking photo of the territory was carried out using UAVs (drones). In the course of the work, it was established that there are 14 mudflow hazardous rivers in the territory under consideration. Debris flows are widespread and can be traced on slopes of various exposures. Field surveys have shown that the Kozydon and Zemegondon rivers are also mud bearing, as evidenced by mudflow deposits in the riverbeds. Often the origin of a mudflow occurs in the channel of one of the tributaries, and further movement continues along the main channel. The size and volume of previous mudflows were assessed.
