Human-induced gully erosion and thermoerosion in the west part of Central Yamal

Abstract

Landscape erosion stability of the Bovanenkovsky gas-field in the western Yamal is very low even at natural conditions. It has decreased much more since exploration began, when additional factors of erosion have come to existence. Man-induced gullies appeared close to settlements and derricks. From 1988 their length has grown up to 200-1000 m, depth - up to 4-5 m. All gullies are active and from a real hazard to technical constructions at the gas-field.
