Assessment Engineering Geological Zoning of Kalush City Using ERS Data for Urban Development

Abstract

Summary The methodology of assessment engineering geological zoning of Kalush city of Ivano-Frankivsk region with particularly complicated geodynamical and geoecological conditions was appended. Previously elaborated taxonomic system of territorial units provides the basis for engineering geological zoning. The allocation of large natural geomorphological districts detailing in slopes' steepness classification for construction development and districts, which completely presented by technogenic landforms was initially proposed for Kalush city. Each allocated district is divided on engineering geological sites due analytical assessment of geotechnical, hydrogeological, geodynamical conditions and ecological and engineering geological planning restrictions. Multi-temporal space images from 2005 to 2017 years with manifestation of different supergene geological processes were analyzed to better assess of geodynamical situation. Four categories of sites with different levels of suitability for construction were allocated, including useless city's sites for constructions, which require primary urgent reclamation measures on whose realization the ecological balance of geological environment of Kalush and the health of him inhabitants in future depends. The proposed method of assessment engineering geological zoning allows to provide credible and accurate information for the construction development direction's understanding and operational ecological decision making.
