Ecological Systems and Devices Annotation << Back The Present Ecological Situation of the River Duruji G.V. Gavardashvili The analysis of many year theoretical and field-expeditional research were conducted that allows to assess the ecological condition of basin of the River Duruji. Concretely, on the basis of statistical date, the dependences establishing stability of Armoring of riverbed of the River Duruji after the passing of debris flow is received. According to empirical dependences and time factor, the coefficients and erosion classes with taking into account the damage level in the basin of the River Duruji are established. According to 100 year (1899 – 1999) statistical date, the dependences establishing the maximal discharge of debris flow with different provision and volume of debris mass transported by the River Duruji are received. On the basis of theory of liability and risk, the density of function of debris flow maximal expenditure distribution of Veibul, is established. E-mail: givi.gava@mail.ru
