Morphometric assessment of gullies based on field measurements

Abstract

Observations of 55 gullies in Northen Kazakhstan were used as a basis of a new method developed to evaluate the rate of various kinds of erosion (lateral erosion, downcutting, backward erosion). The procedure includes a series of one-time measurements of the gully's depth and width equally spaced from the head towards mouth of the gully. Coefficients and their combinations are introduced to calculate a contribution of each kind of erosion to the general process of gully formation.
