T19. Geomorphological and historical analysis as a research tool for the identification of geo-hydrological risk prone-areas

-

Congressi SGI-SIMP

Geohydrological processes are common and widespread phenomena. Recent decades have seen an increase in intense and short-duration rainfall events caused by global warming, which in the Mediterranean area is manifested by an increase in air temperatures and changing in rainfall regime. Landslides, floods, and mud-debris flows, increasingly involve structures and infrastructure built in hazardous areas, such as those of fluvial pertinence or in landslide prone-areas, due to inadequate land use planning.
The evolution of geohydrological processes can be properly assessed in space and time through a solid knowledge base consisting of a large amount of information, among which historical documents (manuscripts, published and unpublished publications), as well as iconography (paintings, sketches, photographs) and historical cartography (geological maps and technical plans), capable of defining geomorphological dynamics and thus to add information in terms of hazard and risk, assume relevance. To these can be added particular historical records such as flood notches, marble plaques, and memorial stones that complement a special multi-temporal dataset on geo-hydrological processes. All this historical documentation, once selected, validated and properly interpreted on a scientific basis, can be organized in a database and used for land-use planning, event forecasting and proper geohydrological prevention.
