Resumo(s)
The objective of the present study is to evaluate the relation between the spatial and temporal
dynamics of Land Use and Land Cover (LULC) and the hydro-geomorphological
processes and their impacts. The study area is the city of Leiria, in central Portugal, within
the period 1958–2018 based on the historical record of floods and landslides disasters.
The LULC analysis shows an accentuated increase in the artificial areas and a continuous
decrease in the agricultural areas. With regard to hydro-geomorphologic disaster occurrences,
a total of 124 occurrences were identified, having caused a set of impacts. The
obtained results allow one to characterize the artificialization process, its intensity and territorial
dispersion, as a consequence of urban sprawl and peri-urbanization, along with its
consequences in exposure to hydro-geomorphological processes. The analysis concludes
that changing the risk drivers resulted in an increase in frequency and spatial dispersion of
hydro-geomorphologic disasters over the analysed period.
