    Beskrivelse

    At present , urbanisation is taking place . A s cities expand ,
    areas previously omitted due to construction risks are now
    being urbanised. These areas are typically characterised as
    those with unforeseen soil properties , unknown
    groundwater conditions and the risk of flooding from the
    sea or rivers . Thus, to utilise these areas urban planners
    need detail ed information about the geology, hydrology
    and future climate impact on the area. W e have
    investigated how high-density geophysical data in
    combination with geotechnical data , borehole data and
    GIS data could be used for develop ing a high-resolution ,
    3D geological voxel model for Ny Rosborg. I n this
    model , specific geotechnical values can be assigned to
    each voxel thus providing a 3D overview of the
    geotechnical properties of the study area. The 3D
    geotechnical model enables city planners to identify those
    areas that are the most sustainable and cost-effective to
    develop . The 3D model output was combined with a map
    showing areas prone to flooding enabling the construction
    of a series of planning maps show ing the most suitable
    locations for green areas ( such as parks), blue areas ( such
    as lakes or wetlands) and grey areas ( such as buildings or
    roads) within the Ny Rosborg area.
