Abstract
Flood databases of high spatio-temporal resolution
are a necessary tool for proper spatial planning, especially
in areas with high levels of exposure and danger to floods.
This study presents the preliminary results of the Spanish
Mediterranean Coastal Flood (SMC-Flood) database cover ing the municipalities in this region. This database collects
information on flood cases that occurred between 1960 and
2015 by systematically consulting the digital archives of the
main newspapers in the study area. The search for flood in formation was conducted by means of using links between
municipality names and seven keywords that correspond to
the most common ways of referring to a situation that is
likely to describe a flood in Spain. This methodology has en abled the reconstruction of 3008 flood cases at a municipal
scale with daily resolution while gathering information on
the types of damage, intensity, severity and area affected. The
spatio-temporal analysis of the data reveals hotspots where
flood cases are especially intense and damaging when com pared to highly developed areas where the frequency of flood
cases is very high. This situation is especially worrying in sofar as we have detected a growing trend in the frequency
and area affected by flood cases. However, one positive as pect is that the intensity and severity of flood cases follows a
falling trend. The main novelty lies in the fact that the high resolution spatial analysis has made it possible to detect a
clear latitudinal gradient of growing intensity and severity in
a north–south direction. This pattern calls for new actions by
the coastal municipal authorities of southern Spain for adap tation to a more complex flood scenario
