Urban geology can be considered as the field of Applied Geology that
deals with major population centres and it analyses the interaction
between the constructed environment with engineering activity and the
geological settings and natural processes. Studies cover a wide field,
and A series of maps has been produced showing, for example geological
formations, surface and groundwater conditions, environmental
vulnerability, potential hazards, construction suitability, and the raw
material occurrences outside of the urban zones.
The regional engineering geological mapping of Budapest was
undertaken in the 1970s. The 1:10 000 scale geological maps and
accompanying detailed reports provided the basis geo-database of the
capital, after the urban area growth and change those tracking show
anomalies in time and location. The urban geology project of Budapest
(Hungary) started in 2001 and since that time 13 of the capital's
districts have been mapped by the Geological and Geophysical Institute
of Hungary (before 2012 by its predecessor, the Geological Institute of
Hungary). From 2013 the maps and their geological data were translated
into GIS format (in the Hungarian EOV system) with the basic aim to
create a geo-database for urban areas and to keep it up-to-date.
The method of investigation was founded on international and national
standards and regulations accepted in the years from 1970 to the 1990s.
And nowadays the mapping has reached its original aims, representing
geological digital data of the Hungarian capital and all 19 counties
nationwide.
The results of the work are the followings:
In the capital:
Engineering Geological Map Series of Budapest 1:10 000; 28 atlas
Engineering Geological Map Series of Budapest 1:20 000; 9 atlas
Engineering Geological Map Series of Budapest 1:40 000; printed
edition
Budapest Urban Geology GIS Database (Hungarian EOV systems)
The districts of Budapest Urban Geology Map Series 1:10 000 / 1:20
000 / 1:25 000
Budapest Agglomeration Regional Development Map Series 1:100 000
The engineering geological assessment of the mapped potential
geological hazards at the Danube Bend, 1:20 000
In the counties:
In parallel, there has been national mapping at 1:100 000 scale,
where the depth of ground water level, the surface expression, the
engineering geological conditions and the raw material occurrences were
summarised and presented alongside surface movement hazards.
