| Summary: | There are various approaches available for assessing the flood
vulnerability and damage to buildings and critical infrastructure. They cover
pre- and post-event methods for different scales. However, there can hardly
be found any method that allows for a large-scale pre-event assessment of the
built structures with a high resolution. To make advancements in this
respect, the paper presents, first, a conceptual framework for understanding
the physical flood susceptibility of buildings and, second, a methodological
framework for its assessment. The latter ranges from semi-automatic
extraction of buildings, mainly from remote sensing with a subsequent
classification and systematic characterisation, to the assessment of the
physical flood susceptibility on the basis of depth–impact functions. The
work shows results of the methodology's implementation and testing in a
settlement of the city of Magangué, along the Magdalena River in
Colombia. |
