Phase 1 (10.2011-12.2012)
Identification of urban disparities according to the historical evolution of the city
Summary
The aim of Phase 1 was the identification of the geomorphological instability of Bucharest, as the source of environmental vulnerability. In an urban area, this is made possible through a historic approach, inter-conditioned by natural and man-induced factors. The phase implied three tangible objectives through inter-conditioned activities that were fully implemented. Part of the results were presented at 5 international conferences and in one article published in the ISI Journal Natural Hazards and Earth System Sciences– (NHESS) - http://www.nat-hazards-earth-syst-sci.net/13/1481/2013/.
In order to reach phase 1 overall objective, team members have attended various training courses, software required for spatial data processing and SAR were purchased. InSAR processing was conducted by PhD Eng. Necsoiu Marius, at the USA SwRI Research Institute, Division of Geosciences and Environmental Engineering.
The most important activity in 2012 was the interferometric analysis aiming to identify instabilities at city's topographical level. The result of 2012 phase includes a detailed GIS data-base, readable with the ArcMap 9x: and areas of deformations reproduced through coordinates, heights, vertical movements (subsidence), displacement rate, speed, standard deviation, coherency, season variations. The interferometric analysis was validated through field surveys and the diachronic analysis of historic documentary evidence, especially the map's from 1900, which represented a historic landmark of city's topographical surface.
