Pluvial floods as a harmful effect of the global climate change process may occur
more and more frequently in
urban areas. With determination of environmental vulnerability the vulnerability pillar
of the impact assessment
can be given. The environmental vulnerability depends on three factors: slope, water
coverage and the drainage
capacity of the earth. Since the drainage capacity of the surface water depends on
the soil’s clay content, with a
careful calibration of GPR survey the soil factor can be derived from the attenuation
of EM waves. This study
presents the determination process of environmental vulnerability and with a field
example illustrates its
applicability where the designation of vulnerable zones was done by using conventional
method and the based on
GPR survey as well. The field test showed that based on the attenuation of EM waves
more precise and reliable
vulnerability assessment can be carried out than with the conventional delineation
method of the endangered areas.
