| Zusammenfassung |
| On 20 February 2010, an extreme rainfall episode occurred on Madeira Island,
which caused an exceptionally strong flash flood and several soil slip-debris
flows, producing 45 confirmed deaths and 6 persons declared missing, as well
as extensive material damages. In order to understand and quantify the
importance of landsliding in routing sediment through mountainous drainage,
such as Madeira Island's landscape, it was essential to perform extensive
landslide analysis. This study describes the methodology used to
semi-automatically detect the landslides, produce the landslide inventory
maps and estimate the sediment volume produced during this particular event
which ranged from 217 000 m3 to 344 000 m3 and 605 000 m3 to
984 000 m3 for the Funchal and Ribeira Brava basins, respectively. These
results contributed to the design and implementation of measures to prevent
damages caused by landslides in Madeira Island. |
