Investigation of the conditions for the development of quarries of non-metallic building materials on the Upper Belaya, taking into account their impact on the level regime

Abstract

Currently, the Belaya River is in rather difficult hydrological and navigable conditions, which is generally due to the low water content in the region and the many years of mining of non-metallic building materials actively carried out here. Under existing conditions, it is not enough to ensure guaranteed dimensions of the ship's course only by carrying out track work and strict regulation of production volumes is necessary. As part of the research carried out, the main tasks of conducting hydraulic calculations and methods of their solution are considered, the results of hydraulic calculations of the landing of water levels from quarrying are presented, which showed that in a significant part of the site (33 km of the 76 km studied) further quarrying should be completely prohibited until the restoration of the riverbed and the introduction of building materials quarries on the site; the possibility of quarrying at three sites in limited volumes was allowed; recommendations were given on the parameters of building materials production at a promising field for development. The paper also assesses the impact of dredging for navigation purposes on the amount of water level landing, which showed that they play a secondary role in the general anthropogenic impact on the Upper Belaya riverbed, but at the same time intensive channel mining of building materials and dredging is impossible due to their significant combined effect on the level regime. The implementation of the conclusions and recommendations obtained from the research results will minimize the adverse impact of mining operations.
