APPROACHES TO FORMALIZATION OF ASSESSMENT OF TERRITORY ENGINEERING GEOLOGICAL COMPLEXITY FOR PURPOSES OF SUSTAINABLE URBAN DEVELOPMENT (THE CITY OF MOSCOW CASE STUDY)

Abstract

The present paper addresses methods for formalization of engineering geological complexity of urban territory based on engineering geological zoning for purposes of urban and spatial planning. Presented is distinguishing three main sets of issues for purposes of urban development complex, improvement of environmental management and assessment of engineering geological complexity distribution, issues being addressed at two levels: at the city level - mapping the engineering geological complexity to scale of 1: 100 000 and at municipal level – engineering geological complexity maps to scale of 1: 25 000 with derivation of taxonomic formula of geological hazard; at that, cartographical materials are proposed as open data. For the first time it is proposed to use the complexity index and to plot the diversity curves for negative geological processes. Results of distribution analysis for complexity of engineering geological conditions made it possible to reveal a relatively low complexity of the structural uplift megamassif at the territory of the city of Moscow. The proposed methods shall help to develop "geoecological image" of the city and be used for better understanding of geoecological problems related to the city development.
