L’idea della ricerca nasce dalla presenza sulla costa est della Corsica dell’antica città romana di Aléria scavata negli anni 1950-60 dai Coniugi Jehasse, su tale sito archeologico a 45 metri di quota, a 3 KM dal mare si applica tale progetto pilota, atto a promuoverne la ripresa e ottimizzazione degli studi, sia delle evidenze architettoniche, che dei reperti e dei dati delle stratigrafie romane e preromane degli scavi per una migliore fruizione del bene.

The aqueducts are the most impressive and original building of the ancient Rome. The aqueducts moved water only by gravity, being constructed with a slight downward slope, within conduits of stone, brick or concrete. All along valleys or plains, the conduit was supported by buildings with arches, or its contents were placed to pressure in lead, ceramic or stone pipes. The aim of this work is to study and determine the slope and so to evaluate the actual flows, considering also that the area is interested by crustal movements.

In the last years, Ground Penetrating Radar (GPR) technology has been extensively used in several different fields, including archaeology and cultural-heritage diagnostics. The integration of GPR with other positioning devices, such as a Global Positioning System (GPS) and an Inertial Measurement Unit (IMU), can significantly improve the accuracy of buried-object location, by means of an efficient control of GPR route and attitude.

The knowledge of water vapour distribution is a key element in atmospheric modeling and considerable information, also at the local scale, can be derived from the GPS-ZTD (global positioning system-Zenith total delay) data.
This paper shows the assimilation of GPS-ZTD data into the RAMS@ISAC (Regional Atmospheric Modeling System at Institute of Atmospheric Sciences and Climate of the National Research Council) to improve the representation of the water vapour in the meteorological model.

Landfill monitoring requires knowledge of the landfill body's volumetric characteristics at frequent time intervals. In addition to this three-dimensional information, other information may also be useful, such as surface temperature, which may be influenced by the chemical, physical and geotechnical processes inherent in the development of the landfill itself. On the other hand, the logistical and environmental conditions normally encountered at such sites make it difficult to use traditional geomatic techniques.

The drones allow to acquire geometric and thematic information quickly and with considerable operational advantages in close range surveys. The lower flight altitude, and the possibility of rapidly replacing the sensors between panchromatic, multispectral and thermal sensors allow the detection of useful characteristics for monitoring and control, even periodically, of areas with reduced size.

The sinkhole known as 'Pozzo del Merro' possesses unusual, geological and natural features, providing an important opportunity to study the geological and hydrological characteristics of the area, and, at the same time, to preserve an ecosystem inhabited by rare species. The site has been the object of numerous studies carried out by scholars from a wide range of disciplines, but a true morphological survey has not been performed until now due to logistical difficulties that include the lack of adequate measuring positions and the difficulty of establishing a clear view between points.

The aim of this study is to test the applicability of GNSS receivers for monitoring the movement of trees associated with the wind. The analysis was carried out locating a single frequency GNSS receiver at the top of the trunk of an Italian stone pine (Pinus pinea L.) and evaluating the results obtained in terms of speed, positions and frequencies. Subsequently, the values obtained were correlated to the characteristics of the wind. Preliminary goal of the experimental activity was investigating the quality of the data obtainable.
