Abstract

Rating curve method is used largely in various calculations of suspended sediment flux in different environments. This paper shows, how this empirical method can be extended on estimation of sediment flux from ungauged watersheds. Permafrost influence on processes of sediment formation is examined. Aspects of GIS analysis of environmental data as applied to estimation of sediment fluxes are reviewed.

Keywords: rating curve, ungauged watersheds, GIS techniques, permafrost conditions
