НОВІТНЯ ЗАБУДОВА ХМЕЛЬНИЦЬКОГО: ЗМІНИ МОРФОЛОГІЇ ПОВЕРХНІ ТА СУПУТНІ ПРОЦЕСИ

Abstract

The article presents results of research in 2010–2017 on site in the Pivnichnyi (ukr.North) district of the Khmelnytskyi City. The terrain topography evolved here from mostly natural into almost completely anthropogenic. This change was caused by the latest construction development. As a result, gentle and moderate slopes of balka turned into cascades of artificial terraces with ledges up to 6 m high, the valley bottom is now bulked. In general, the maximal capacity of bulk deposits in the studied area reaches 7,5 m. Natural features contributed to linear erosion, landslides, subsidence, waterlogging, human activities stopped the action of some (erosion, waterlogging, subsidence), but activated other (landslides). After human impact landsliding occurs in the bulk deposits and engineered sediments, as well as in the recently opened naturalsediments. For example, Neogene clays get dry, crack and spread. Other types of landslides are the rotational, shallow translational and slowearthflow. Earlier only the small rotational landslides and, most likely, earthflows have happened on the left balka's flank. Activation of landslides began in 2013. The conclusions are based on the field observations in 2010, 2014–2017, interviews, as well as on interpretation of geotechnical engineering data by "Khmelnytskyi Budrozviduvannya" and "Zhytomyr Budrozviduvannya" (ukr.Khmelnytskyi / ZhytomyrConstr[uctional] Investigation). Key words: urban geomorpology, artificial terrain, artificial terraces, engineered sediments and bulk deposits, landslides, Khmelnytskyi City.
