The NW Mediterranean region experiences every year heavy rainfall and flash floods that occasionally produce catastrophic damages. Less frequent are floods that affect large regions. Although a large number of databases devoted exclusively to floods or considering all kind of natural hazards do exist, usually they only record catastrophic flood events. This paper deals with the new flood database that is being developed within the framework of HYMEX project. Results are focused on four regions representative of the NW sector of Mediterranean Europe: Catalonia, Spain; the Balearic Islands, Spain; Calabria, Italy; and Languedoc- Roussillon, Midi-Pyr´en´ees and PACA, France. The common available 30-yr period starts in 1981 and ends in 2010. The paper shows the database structure and criteria, the comparison with other flood databases, some statistics on spatial and temporal distribution, and an identification of the most important events. The paper also provides a table that includes the date and affected region of all the catastrophic events identified in the regions of study, in order to make this information available for all audiences.

Tornados a Catalunya

Desgraciadament durant aquests dies es parlarà del devastador tornado a Oklahoma City, que ha causat de moment 91 víctimes mortals. Als EEUU és molt comú que durant certes èpoques de l’any es formin tornados, sobretot al centre del continent. Tanmateix tornados tan desoladors com aquest que ha estat un tornado de categoria F4 (320-420 km/h) no són freqüents.

A Catalunya, no és tant freqüent i la intensitat és molt menor, però tot i així algunes vegades s’han registrat tornados i bastant freqüentment es poden contemplar mànegues marines davant la costa.

IAEG XII Congress

The IAEG XII Congress aims to analyse the dynamic role of Engineering Geology in our changing world: by means of a series of topics and sessions offered to the participants’ choice through the interpretative key of four main themes:


In the next few years, major effects over territorial planning and infrastructures will be due to the global change particularly evident in extreme climate regions. Climate changes also affects natural processes related to slope dynamics, water courses, coastal and marine environments: all these phenomena are case studies for Engineering Geology.

Engineering Geology plays a major role in the definition of human responses to the changes of a dynamic environment. More and more obvious is the role of territorial planning for a sustainable use of available geo and water resources and a proper management of natural hazards (as landslides, floods, marine processes and earthquakes). Urban Geology and Applied Geology for Major Engineering Projects are reaching far beyond technological applications, because they analyse the evolution over time of the Society and infrastructures, including also the Preservation of Cultural Heritage.

Indeed, human activities have to be developed on a ethical base: Engineering Geology respects this principle, where implications include sustainable future and environmental conservation.

One  session is DOWNSCALING CLIMATE INFORMATION FOR IMPACT STUDIES, where the convener is Dr Marco Turco and Co-Convener are Maria del Carmen LLasat Botija and Jost von Hardenberg. And another is about CLIMATE CHANGE: IMPACTS ON NATURAL RESOURCES AND HAZARDSConvener:  Dr Maurizio Polemio Co-Convener: Marta Chiarle and Young Researcher: Marco Turco
