Debris Flows at the River Mletis Khevi (Greater Caucasus Mountains, Georgia) and its Assessment Methods
The erosional debris flow processes on the right side of the riverbed of Mletis-Khevi, a tributary of the Tetri Aragvi, are assessed on the basis of field and laboratory studies. The values of the mountain slope erosion in the Mletis-Khevi catchment area have been determined on the basis of field studies, taking into account the time factor and the extent of slope damage. Dependences are derived by means of the maximum discharge of debris flow of various intensities. Furthermore the volume of transported debris flow mass is calculated. A physical-mechanical and chemical analysis of the debris flow mass has been carried out in the laboratory. The results can be used at a subsequent stage for predicting the various basic characteristics of debris flows. --debris flow,discharge,erosion coefficient,catchment area

Effects of cohesive mudflow on semi-cylindrical antimud structure
Counteracting the phenomenon of debris flow is implemented in various ways. As international practice has shown, hydrotechnical constructionsoccupy a special place among structures regulating debris flow. Despite the large variety of constructions, each of them has a strictly defined purpose. The specifics associated with the hazards of debris flow in a given area are taken into account when selecting such a construction. The work indicates the expediency of applying semi-cylindrical openweb constructions to regulate debris flow. The methodology of selecting the design elements is presented. A specific example of the construction calculation and graphic
illustrations are presented
Development of the debris flow control elastic barrage design methodology
In this paper, we present the debrisflow regulatory barrages innovative construction specifications. By evaluating the dynamic nature of debrisflows we determine the methodology
of building debris flow regulating constructions and specific elements in said constructs.
By taking in mind the river bed and its topographical parameters, we determine debrisflow
regulatory elastic barrages geometrical size and we mapped out its designs specific example. By assessing the maximum discharge of the debrisflow, we determine its, dynamical,
influence metrics, which in practice helps us assess the constructions reliability and risks
of it being rendered unusable by the aforementioned factors
Determination of Contours of Flooded Areas Due to Possible Accident of Zhinvali (Georgia) Earth Dam and Calculation of the Hydrodynamic Parameters of a Destructive Wave at a Dam
Using theoretical and field studies, computer software programs (VOLNA-4, and MIKE-21, ) and GIS technology, and taking into account the possible accident (destruction) of the Earth Dam with a height of 102 meters, the contours of the riverbed of flooded territories in riverbeds for rivers Aragvi and Mtkvari have been defined in the given article considering the configuration of the water-catchment basins of rivers.
By means of basic differential equations of hydraulics, geometrical dimensions of Zhinvali Earth Dam, hydrological basic parameters of the reservoir, and computer software, the basic hydrodynamic parameters of the destructive wave at the Zhinvali Earth Dam are calculated taking into account the time of flow movement
