Conclusion
This study examined hydrological processes at the Suntar River Basin (area 7680 km2, elevation range 828-2794 m) located in the highlands of the Indigirka River using the hydrological model Hydrograph.
Currently, in the mountain regions of the Yana, Indigirka and Kolyma rivers basins, no hydrological research stations are operational to perform a comprehensive study of runoff formation processes. Therefore, development and verification of methods for hydrological process modeling which can successfully utilize short-term, extremely scarce data, become of greater interest. The study has demonstrated that the Hydrograph model and its further development may become a foundation for solving scientific and practical issues in permafrost regions.
