Abstract

The main objective of the present study is to build a spatial model of the geotechnical properties and
radiometric measurements for site selection of urban extension at the study area by using geographic
information systems (GIS) techniques to develop and analyze a site model and also to make sound decisions
and to plan site activities at the New Alamein City. In the geotechnical site evaluations and radioactive
measurements, GIS can be used in four methods, data integration, data visualization and analysis, planning
and summarizing site activities, and data presentation. The integrated data can be displayed as contour
maps; manipulated and analyzed using tools built into the GIS programs, thus creating the geotechnical and
radioactive site model of the study area. Explanation of these data needs the spatial location to integrate
into the analysis. Mechanical and physical properties of the soil, chemical analysis, and radioactive data
are weighted. Finally, the weighted maps are integrated using a GIS based on the construction purposes for
the new extension of New Alamein City for note worthy cost savings in design, construction, and long life.
The very high and high zones highest regime has been observed towards the most of the study area but the
moderate zones are observed toward the northern side of the area and the low is the smallest zone toward
the southern side of the study area.
