Abstract
The purpose. To study dynamics and state of evolution of gullens in conditions of Steppe of Northern Ukraine on an instance of Lugansk oblast. Methods. Cartographical with determination of morphometric indexes of different links of hydrographic network by means of SIS techniques, mathematical-statistical and field surveys. Results. Analysis of indexes gully erosion has determined substantial increase of annual increase of gullens for the last 25 years. By results of analysis mathematical model which formalizes process of gullying is created. Conclusions. At saving trend of increase of gullens their firmness will be augmented from 2,6 up to 3,65 units/km2, thickness — from 1,59 up to 2,34 km/km2. The yielded state requires the further study of the process of gullying and heading of soil-protection measures.

Key words: gullen, hollow, scour, hydrographic network, erosion
