Commission IIKEY WORDS : Emergency survey, Digital recording method, Close range photogrammetry, Virtual archaeology, AR and VR for CH ABS TRACT:The research is an analysis of the recording, reconstruction and visualisation of the 3D data of a XVIII century watermill, identified in an emergency archaeological excavation during the construction of the mini-hydroelectric plant on the bank of the Adda river in the municipality of Pizzighettone (Cremona, Lombardy, Italy ). The work examines the use and the potentials of modern digital 3D modelling techniques applied to archaeological heritage aimed to increase the research, maintenance and presentation with interactive products. The use of three-dimensional models managed through AR (Augmented Reality) and VR (Virtual Reality) technologies with mobile devices gives several opportunities in the field of study and communication. It also improves on-site exploration of the landscape, enhancing the "minor" archaeological sites, daily subjected to numerous emergency works and facilitating the understanding of heritage sites. INTRODUCTIONThis research is an analysis of the recording, processing reconstruction and visualisation of the 3D data of a XVIII century watermill identified in an emergency archaeological excavation. The discovery, unearthed during the construction of the minihydroelectric plant, is located on the left bank of the Adda river in the municipality of Pizzighettone (Cremona, Lombardy, Italy).The aim of the paper is to show the possibilities offered by digital technologies, mostly the digital photogrammetry and the virtual archaeology, to record and enhancing the "minor" archaeological sites that are daily subjected to numerous emergency surveys over the entire territory. M ost of these interventions consistently produce vast amounts of data that are often confined to the archives and therefore not accessible to the public. * Corresponding authorThis work examines the use and the potentials of modern digital 3D modelling techniques applied to archaeological heritage to increase the divulgation and visualisation with interactive products. During fieldwork, the methodology and software employed were very sustainable, intended at surveying the site and considering the issues related to the disclosure of the acquired and processed archaeological data; in this way the collected information could be understood not only by scholars and professionals, but also by a larger audience.The paper presents furthermore a case study, replicable in other emergency excavations sites, where archaeological remains, discovered as a result of urban works, are acquired and processed directly on the place of occurrence, non-invasively and through the use of low cost technologies.

The Estimation of the relative intensity of different cold periods occurring during the Late Quaternary is a difficult task, particularly in non-glaciated mountain landscapes and where high- to medium-resolution archives for proxy data are lacking. In this paper, we study a Holocene polycyclic soil sequence in the central Alps (Val Cavargna, Northern Italy) to estimate climatic parameters (specifically Temperature) changes in non-glaciated, high altitude environments. We investigate this key site through palaeopedological and micromorphological analyses in order to understand phases of soil development and detect hidden evidence of cold conditions during its formation. Three phases of pedogenesis can be recognized and attributed in time to different periods during the Holocene. Pedogenetic phases were separated by two truncation and deposition episodes related to the reactivation of slope processes under cold conditions at the onset of the Neoglacial and the Iron Age Cold Epoch, respectively. Micromorphological evidence of frost action in the soil can instead relate to pedogenetic processes acting in the Little Ice Age. The different expression of these three cold periods corresponds to changes in climatic conditions, pointing to the Little Ice Age as a cooler/drier period in comparison to the preceding ones.

<p><strong>Abstract.</strong> The work is an analysis of the recording, processing and presentation of the 3D data of two late roman towers inside the area of the Archaeological Museum of Milan, part of the city previously occupied by the Monastery of St. Maurizio and rich of historical and ancient monuments. The aim of this research is to examine the possibilities offered by digital technologies to record and enhance the archaeological heritage and to increase the divulgence and presentation with interactive products.</p>
