Morphological characteristics of ephemeral gullies in Sicily, south Italy
2011
Ephemeral gullies (EGs) are channels of different sizes refilled by tillage equipment normally used on farms. In this paper, the data-set collected from 1995 to 2007 in a wheat-cultivated area in Raddusa (Sicily, Italy), having a surface of almost 80 ha, were used to analyze the morphological characteristics of EGs. The measurements show an high temporal variability in EG characteristics. The EG measurements and the rill erosion measurements carried out in 15 plots located in the experimental “Sparacia” area (Sicily), demonstrated that a morphological similarity condition exists between rills and ephemeral gullies. The occurrence of step-pool structures in an EG occurring in the observation…
Rilievo e modellazione della rill erosion nell'area di Sparacia
2012
Nella presente indagine, l’applicabilità sia delle relazioni che caratterizzano morfologicamente i rill di Sparacia sia di quelle che ne caratterizzano la geometria idraulica viene testata utilizzando nuove misure condotte in occasione dell’evento del 3 Ottobre 2011. Le suddette misure sono state effettuate su una parcella in cui sono stati rilevati 19 rill e 231 sezioni trasversali. Il confronto delle nuove misure con la relazione lunghezza-volume e con quella dedotta teoricamente sulla base dell’analisi dimensionale, entrambe calibrate con i dati rilevati in precedenti eventi, ha confermato l’applicabilità delle suddette espressioni.

Sviluppo e valutazione di pratiche soglie per separare le piogge erosive responsabili di processi interrill e rill
2018
For the experimental station Masse threshold levels able to separate interrill erosive events from non erosive events were developed and tested. The Masse database was composed of 258 rainy events (189 non-erosive events and 70 interrill erosive events). Thresholds for separating erosive-interrill events from erosive-rill events were developed and verified at Sparacia analysing 77 erosive events (64 interrill and 13 rill). At Masse the threshold in terms of event rainfall depth, Pe, was, among the analyzed variables, the most effective one to distinguish between non-erosive and erosive interrill rainfall events. The rainfall events with a total depth Pe > 13 mm are identified as interrill e…
In vivo exposure of the marine sponge Chondrilla nucula Schmidt, 1862 to cadmium (Cd), copper (Cu) and lead (Pb) and its potential use for bioremedia…

Abstract The study aimed to test the cadmium (Cd), copper (Cu) and lead (Pb) bioaccumulation capacity of the marine sponge Chondrilla nucula and to measure the expression of metallothioneins (MTs) by a western blotting assay to explore metal tolerance and its potential use as a bioremediator in contaminated coastal areas. C. nucula was sampled in a protected marine area in order to perform experiments on organisms living in a healthy environment. Under laboratory conditions, the sponges were exposed to increasing concentrations of Cd, Cu and Pb in tanks filled with artificial seawater set up for the experiments. For each metal, three waterborne concentrations (mgL−1) of Cd (0.02–0.04-0.08),…
