Geomorphological and Morphometric Analyses of the Catanzaro Trough (Central Calabrian Arc, Southern Italy): Seismotectonic Implications
2022
In this work, we investigated the landscape response to the recent activity of the faults affecting the Catanzaro Trough, a seismically active structural basin that developed transversally to the Calabrian Arc (Southern Italy) during the Neogene–Quaternary. We carried out a geomorphological and morphometric study of the drainage networks and basins intercepted by the Quaternary faults that were previously mapped through remote and field analyses. The study confirms the occurrence north of the Catanzaro Trough of a WNW–ESE-oriented left-lateral strike-slip fault system (here named the South Sila Piccola Fault System), which accommodates the differential SE-ward migration of the u…
Derivation of rainfall thresholds for pluvial flood risk warning in urbanised areas
2016
In the recent past throughout the Mediterranean area, many extreme events such as floods, debris flows and landslides occurred. Mediterranean ephemeral streams have specific features compared to other river systems; their basins are small and highly torrential and may generate flash-floods (Camarasa-Belmonte & Soriano-Garcia, 2012). Moreover, the rapid transformation processes of urban areas induced the increase of catchment imperviousness and the derived increase of surface runoff generated during rainfall events. However, flooding events in urban areas occur quite frequently as a consequence of rain events of lower intensity than the design one, even in case of correct network dimensionin…
Perspectives urbaines et écologiques. Le territoire de l’Expo 2008 Saragosse
2013
Les villes fluviales, aujourd’hui confrontées à la rénovation des berges et des espaces attenants, ont pris conscience de leur intérêt à tirer parti de cet élément naturel, constitutif de leur territoire, participant de leur identité mais aussi vecteur de développement. Cette nouvelle sensibilité vers un environnement de qualité s’appuie aux notions d’écologie et de développement durable qui accompagnent la plupart des projets autour du fleuve. Cohérente avec l’importance actuelle concédée à l’impact et à l’héritage apprenant de cette expérience, interprétant le milieu, Saragosse a proposé une Exposition dont la principale vertu réside dans son échelle, dans son dialogue avec l’Ebre et d’au…
Vincenzo Melluso, Un viale urbano di 120 KM, conversazione a cura di Giuseppina Farina
2012
Una fase della presente ricerca si è svolta attraverso diversi incontri seminariali. Uno in particolare ha raccolto l’esperienza scientifica, didattica e professionale sviluppata intorno al tema del rapporto fra la città di Palermo e il suo sistema delle infrastrutture viarie come la circonvallazione e l’autostrada. Sono intervenuti, in questa occasione, in qualità di relatori: Giuseppe Guerrera, che ha illustrato lo studio condotto in ambito professionale in merito all’elaborazione del piano di fattibilità per alcuni progetti in relazione all’asse della circonvallazione di Palermo; Vincenzo Melluso, il cui intervento dal titolo Un viale urbano di 120 km ha riportato l’esperienza svolta con…

La valle dell'Oreto e la città di Palermo: quale parco?
2009
L’interpretazione dei caratteri storico-naturali e delle forme dell’insediamento nel territorio del fiume Oreto e l’individuazione di ambiti unitari suggeriscono strategie di mantenimento e/o recupero delle componenti attive del paesaggio agricolo e di gestione degli spazi aperti metropolitani come beni comuni.
A paradigm of extreme rainfall pluvial floods in complex urban areas: the flood event of 15 July 2020 in Palermo (Italy)
2021
Abstract. In the last few years, some regions of the Mediterranean area have witnessed a progressive increase in extreme events, such as urban and flash floods, as a response to the increasingly frequent and severe extreme rainfall events, which are often exacerbated by the ever-growing urbanization. In such a context, the urban drainage systems may not be sufficient to convey the rainwater, thus increasing the risk deriving from the occurrence of such events. This study focuses on a particularly intense urban flood that occurred in Palermo (Italy) on 15 July 2020; it represents a typical pluvial flood due to extreme rainfall on a complex urban area that many cities have experienced in rece…
OSL dating of sediments from the Gobi Desert, Southern Mongolia
2010
Abstract The present study focuses on the chronological relationship between alternating dune sand and silty water-lain sediments in the central part of the Khongoryn Els dune field in the Gobi Desert, Southern Mongolia. The 23 m high section evolved from the construction of a natural dam by west–east moving sand dunes and fluvial inundation by a river system from the mountain ranges in the south. To resolve the chronology of events, optically stimulated luminescence (OSL) dating was applied and from sedimentological and geochemical analysis the depositional processes could be characterised. Quartz OSL dating of these sediments is hindered by feldspar contamination. Thus, dating of coarse-g…
