Estimation of the recent rate of gully head retreat on the southern macroslope of the East European Plain using a set of instrumental methods
The results of monitoring the gully growth dynamics in different landscape zones of the southern megaslope of the East European Plain are presented. As key sites 104 gully heads in the Republic of Udmurtia, the Republic of Tatarstan, the Voronezh, Saratov and Orenburg oblasts and the Stavropol Krai were chosen. Various instrumental methods were used, such as measuring from a control point, repeated geodetic survey, repeated measurement using a terrestrial laser scanner. The results show a decrease in the annual growth rate of gully heads due to general climate warming and land use change at all key sites. The average annual retreat rate in all areas was 0,45 m/year, with a maximum of 0,78 m/year in the Voronezh oblast.
