DYNAMICS OF EXOGENOUS PROCESSES AT AREAS OF CONSTRUCTING THE OBJECTS OF TOURISTIC COMPLEX «GORNY VOZDUKH»

Abstract

The relevance of the research is caused by the need to ensure the safety of construction and operation of the facilities of the Sport and Tourism Complex «Gorny vozdukh» in Yuzhno-Sakhalinsk. The aim of the research is to detect the signs of activation of exogenous geological processes while constructing the facilities of the Sport and Tourism Complex «Gorny vozdukh», to assess their danger and study their influence on water bodies. Objects: the territory under cable cars, ski slopes, buildings and constructions of the infrastructure and technological roads on the northern and southern slopes of Bolshevik, reservoir on the river Rogatka, water intake on the river Yelanka. Methods: study of the results of engineering surveys carried out by various organizations on the slopes of Bolshevik Mountain; investigation of the operation mode of water intakes on the Yelanka and Rogatka rivers; field survey of the facilities of the Sport and Tourism Complex «Gorny vozdukh» on the slopes of Bolshevik; sampling of water from water bodies for chemical analyzes. Results. In the territories under cableways and newly built ski slopes, bare ground is observed, in places up to the zone of exogenous fissuring and bedrock. In cable trenches there are insignificant drawdowns of bulk ground, caused by gravity densification and suffosion processes. Traces of water erosion are noted. There are no signs of landslide and mudflow activity. Brooks flowing down the slopes are transparent. Construction works in the valley of the Yelanka River affect only the duration of breaks in the operation of the water intake. The influence of the Sport and Tourism Complex construction on water quality in the reservoir on the river Rogatka is not established, the operation mode of the water intake in the reservoir has not changed.
