Abstract

Technogenic landslides induced by engineering activity are found on the sides of the Glebuchev ravine, the largest gully system in the central part of the Saratov City. Deformations of buildings and engineering facilites induced by landslide activity produce threats to the city’s economy and population. The paper describes results of monitoring and retrospective analysis based on archive cartographic data that permitted to follow the gully system development in historical times. Favorable for landslide activity are geological and geomorphological settings, but the key factor is related to economical activity, namely clay and loam quarrying, undercutting of slopes, pouring out waste water, construction activity and other kinds of slope loading. Mitigation measures must be followed by comprehensive recultivation of the gullies territory, namely rearrangement of slope areas, their stabilization by vegetation cover, surface and ground water drainage. It is recommended that the Glebuchev Gully is transformed into recreation park area coming out at the Volgograd Reservoir bank road.
