Oek-river basin was used as a model site for revealing the features of the structure of river basins in the low-water karst region. With the help of the methodical approach of Horton analysis, improved by Yu. G. Simonov, the main structural indices of the basin are deter- mined — indices of bifurcation of lengths, areas, slopes, geomorphological work for sub- basins of the third order. Analysis of the distribution of the indices showed the greatest dis- memberment of the western part of the basin in the upper links of the erosion network. It is determined that the third-order sub-basins located in the western part within the Irkutsk- Cheremkhovo plain have the greatest homogeneity of structural indices, and the sub-basins of the Kudinskaya depression are the most diverse in the distribution of structural indices. The studies of the ratios of different structural morphometric indicators (structural indices and structural coefficients) showed their good correlation with each other, and allowed to determine the areas of their application. Analysis of the distribution of indicators of geomorphological work showed that significant work on the transfer of matter is performed by tributaries of the first order of the western part of the basin, and maximum geomorphologi- cal work is inflows in basins with the largest areas.
Keywords:
