| Summary: | <p>This article presents results for gully head cut retreat rates
(GHRR) in the Pre-Kama region (Republic of Tatarstan, Russia) based on
monitoring (1984–1994 and 2015–2018) and the interpretation of
high-resolution satellite images (2004–2014). The results suggested that the
mean linear GHRR have reduced by about five times, from 1.6 m per year
(1983–1994) to 0.4 m per year (2015–2018). The main reason for the
significant decrease in gully erosion was the increase in winter-spring air
temperatures, which resulted in a reduction in the depth of soil freezing
and surface runoff. The impact of land use, as well as erosion control
measures, which were implemented in the study area during the late 1980s and
early 1990s, was found to be less important.</p> |
