The article discusses the sensitive areas of snow avalanches formed in the mountain landscapes of Georgia and presents their brief geographical, climatic-meteorological and hydrological assessments. By referring to global practices, the characteristics of different constructions of snow avalanche buildings and their reliability are presented. A constructive description of an innovative snow-avalanche-proof building, certified by a Georgian patent certificate, is presented. An innovative method for the design of the building was developed and the construction of the structure was carried out in the Kobi-Gudauri alpine zone of the Georgian military road at an altitude of 2238 m above sea level.

There are hardly any sections in a debris flow channel, where flow movement, except for exceptions, would have a constant hydraulic regime and typical parameters. Therefore, in order to select regulating measures, the urgent means of assessment of the flow regime to totally cover its anomaly is needed. The solution of this question is associated with the full compatibility of laws with soil mechanics and hydraulics. Recently, the engineering problems related to debris flow, based on various considerations, have been realized by integrating the obtained differential equations. Especially important are the possibilities of a debris flow moving regime in prismatic beds described by the system of differential equations of various modifications. If rheological properties are neglected in the above equations, they are completely transformed into differential equations of non-uniform motion of Newtonian fluids. By considering the above-mentioned, the paper gives the calculation methods and practical example of designing an innovative debris flow control barrage, which was realized in the bed of the Mletis Khevi river gorge.
