Abstract

The present research aims to assess the geologic determinants influencing sustainable urban planning of Ismailia City at the Suez Canal Province. GIS data integration was utilized to specify geologic factors influencing the 2010 strategic urban plan. Field observations, chemical properties of shallow groundwater and remote sensing data were integrated using Geographic Information Systems. The acquired satellite images in this research were selected to be within 1990-2014 time span. It is noticed that some environmental problems which are originated following the development of urban and industrial projects in Ismailia City in addition to the extension of informal unmanaged settlement areas. These include waterlogging, salinization and land subsidence. The results of chemical analyses of water indicate exceedance of sulphate content which causes salt crust problem and severely affects the foundation resistance. Also, unexpected urban sprawl produces unplanned urban extensions which are strongly suffered by waterlogging and land subsidence. Change detection emphasized that the newly cultivated land, salt crust and informal settlement areas increased during 1990-2014 period. However, waterlogged areas decreased within the same time period. Consequently, this study recommends considering the geological determinants and environmental factors in any future planning.
