tRIBS-Erosion: combining mechanistic approaches for investigating eco-hydro-geomorphic response of river basins to climate change
2011
Vegetation interacts with hydrology, geomorphology and processes of a river basin in profound ways. Despite recent advances in hydrological modeling, the dynamic coupling between these processes is yet to be adequately captured at the basin scale to elucidate key features of process interaction and their role in the organization of vegetation and landscape morphology. In this study, a newly integrated geomorphic component of the physically-based, spatially distributed hydrological model, tRIBS, the TIN-based Real-time Integrated Basin Simulator, is presented. Hillslope and channel erosion processes are parsimoniously coupled with vegetation-hydrology dynamics, making it possible to study ho…
Mountain Environment and Landscape in prehistoric Sicily: The Madonie region (Palermo, Italy)
2008
The present paper would like to show a research project still in progress, presenting the first preliminary archaeological data. The aim of the Madonie project is to analyse mobility strategies and the use of a mountain territory by prehistoric and historic age population, relating geomorphological features, raw material sources and landscape to settlements. In this occurence we are going to discuss about the prehistoric periods.
Coastal erosion in the archaeological area of Selinunte
2010
Coast erosion is a widespread phenomenon and is a considerable issue for the dwellers of coastal areas today. Our study is based on the archaeological area of Selinunte in which we have noticed a process of erosion in progress. In this area we have considered a particular portion of the coast, around 8 km long, since our purpose is the individuation of anthropic elements such as ports, and natural elements, such as rivers. In this area we have set some point of reference using historical and recent cartography in a 1:25.000 scale dating back to 1971, a regional technical paper in a 1: 10.000 scale from 1994, and aerial pictures from 2000 and 2008, all of which we have geo-related starting f…

Surveying in the Valley of the Temples
2014
Full-waveform terrestrial laser scanning enables high-precision 3D topographic modelling of unstable rock valleys that is valuable for various geomorphological investigations. The area below the archaeological site of Temple of Juno in Agrigento, Sicily, is characterised by the presence of large sections of rock that have fallen down from the upper ridge. In this context, full-waveform laser scanning technology was tested for the production of a highly detailed 3D topographic model at two resolutions (2cm and 20cm) for simulating potential rockfall paths at the site.

Full-Waveform Terrestrial Laser Scanning for Extracting a High-Resolution 3D Topographic Model: a Case Study on an Area of Archaeological Significance
2014
AbstractThis paper describes a method, which uses full-waveform terrestrial laser scanning to survey the surface of the slope below the Temple of Juno, located in the Valley of the Temples in Agrigento (Sicily, Southern Italy). The surface is characterized by the presence of large rock blocks, which have fallen down from the upper side; possible further detachments of rock blocks would cause a situation of general instability, with a very high risk to the archaeological structures in the near future. The methodology was designed to evaluate the potential of full-waveform laser scanning technology for the production of a very high resolution 3D topographic model of the slope, to be used as a…
Stochastic assessment of climate impacts on hydrology and geomorphology of semiarid headwater basins using a physically-based model
2015
Hydrologic and geomorphic responses of watersheds to changes in climate are difficult to assess due to projection uncertainties and nonlinearity of the processes that are involved. Yet such assessments are increasingly needed and call for mechanistic approaches within a probabilistic framework. This study employs an integrated hydrology-geomorphology model, the Triangulated Irregular Network-based Real-time Integrated Basin Simulator (tRIBS)-Erosion, to analyze runoff and erosion sensitivity of seven semiarid headwater basins to projected climate conditions. The Advanced Weather Generator is used to produce two climate ensembles representative of the historic and future climate conditions f…
