No full textDuring September 2015, some municipalities of Val Nure and Val Trebbia areas (Piacenza province) have been affected by a severe rainstorm event which has caused flooding along rivers and debris flows and landslides on slopes. A toll of 3 casualties and serious damages to infrastructures and roads was paid. In the mostly affected areas, rainfall in 6 hours reached 298 mm with an hourly precipitation peak of 107,6 mm/h. In an area of approximately 500 km2, 103 debris flow have occurred. The distribution of debris flows seems to be controlled by the distribution of the intensity of the rainstorm. Debris flows seems to have in many cases caused by slope failures in the upper part of the sub-basins. These phenomena remobilized slope debris that, subsequently, was transported by channelized debris flows. Major damages were suffered at locations where roads are crossing the creeks and streams along which the debris flow occurred. A preliminary analysis of affected sub-basins in one of the areas mostly affected by debris flows, indicates that a straightforward discrimination of the susceptibility of sub-basins based on simple morphometric and lithologic factors is not possible
Transcalarità e adattabilità nel landscape urbanism
No full textNel variegato panorama di contesti disciplinari nel quale il Landscape Urbanism ha sviluppato la propria identità multiforme, esiste chi, come Ciro Najle, ne ha fatto emergere i principi metodologici validi per elaborare una teoria architettonica per progetti di sistemi complessi, a prescindere dal proprio registro scalare.
Tale teoria, come si tenta qui di dimostrare, ha radici lontane e trova in Koolhaas uno dei padri fondatori. Ma è la generazione di architetti formatisi negli anni ’90 che ne determina i connotati più autentici, ristabilendo quella continuità tra forma e strategia, tra forma e tecnica, tra forma e produzione che fin dai tempi del Bauhaus ha definito un approccio pedagogico e sociale all’architettura, e ha delineato un “comportamento disciplinante” dell’architetto chiamato a introdurre lo statuto figurativo e formale nel disegno e nell’attuazione di infrastrutture per il territorio.
I progetti mostrati nel libro – alcuni appartenenti al repertorio di ricerche svolte in ambito accademico dall'autrice - raccontano una sintesi tra architettura e paesaggio che travalicando la tradizionale suddivisione disciplinare in ambiti scalari e tipologici, trovano la propria coerenza non solo nelle premesse scientifiche e ideologiche attribuite a tale metodo ma anche nell’adozione di strumenti operativi e nello sviluppo di tecniche formali – come diagrammi e mapping generativi - che rendono la complessità contemporaneamente il dispositivo e l’oggetto della ricerca

No full textLandslide occurrences and rainfall trend during the period 1951-2010, Emilia-Romagna Region, Northern Italy
No full textThe relation between rainfall trend and landslide occurrences in the Emilia-Romagna region (Northern Italy) is presented. This study is based on the availability of long-term (1931-2017) rainfall data and the Catalogue of Landslide OCcurrences in the Emilia-Romagna region (CLOCkER), which reports the date of more than 14,000 landslides from the Middle Ages to the present. In particular, the analyses focus on the role of rainfall as main triggering factor of landslides that occurred in the Emilia-Romagna region during the period between October 1951 and September 2010. Early findings suggest a well-defined correlation, for different intervals of analyses (annual, seasonal, antecedent rainfall period of ninety days), between the landslide occurrences recorded and the rainfall trend. This demonstrates that rainfall can be considered the main triggering factor for landslides occurring in the Emilia-Romagna region
