Landforms due to subsidence at the Western Caucasus foreland

Abstract

Landforms due to subsidence result from epigenetic increase in density of thick cover loess series. Their formation is controlled by subaerial relief-forming processes, i. e. erosion, piping, leaching, processes due to gravity, privation, abrasion and regelation. In the genetic sequence of negative landforms first are shallow saucer-like depressions and second-more pronounced basins. These forms affect hydrotechnique, industrial and civil engineering, housing and agriculture. Arable lands where the subsidence landforms appeared should be meliorated.
