Gully erosion mechanism and dynamics of channel forms

Abstract

The results of multiannual investigations of water runoff and solid flow in the typical gylly catch basins are discussed. The test site was chosen in the central part of European Russia. Some regular features of gully channel process are established in the test site with the rocks of different density and granulometric composition. Quantitative characteristics of channels morphometry and ephemeral flood streams hydraulics are found. Some field data of gully's debris cone formation in the valley of Protva River are represented.
