metadata.value: The overall increase in precipitation and the frequency of extreme rainfall is confirmed by
  several meteorological observations both on the Black Sea coast of the Caucasus, and in other
  regions with similar environmental conditions. In this context, research on the drivers of
  an extreme meteorological event becoming a severe flood and an extreme geomorphological
  (erosion) event becomes especially important. The article analyses the factors contributing to
  the development of a flash flood on the watershed of the river Tsanyk (Greater Sochi area) and
  estimates its geomorphological impact. Analysis of the hydrologic-meteorological situation
  during the Tsanyk flood on 7–9 September 2018 and in the previous period showed that the
  event is unique for the investigated watershed from the hydrologic perspective. After a prolonged
  period without precipitation, the rainfall on 7–8 September resulted in a flash flood
  with a rapid water level rise (117 cm in 40 min.). We determined the rates and volumes of
  channel erosion based on a repeated survey of the channel section, estimation of the speed
  and length of the banks being flushed out — composed of loose sediments and bedrock — using
  the pin method. The amount of erosion on the banks composed of loosened sediments was
  on average 2–3 times higher than on the flysch banks. At the same time, the material export
  for one erosion event in September 2018 is comparable to (or even exceeds) the total amount
  of bank erosion for a year, previously identified based on stationary observations.
