In particular, the Fisher–Shannon method allows to calculate two quantities, the Fisher Information Measure (FIM) and the Shannon entropy power (SEP), which are used to characterise the complexity of a time series in terms of organisation/disorder. Pilot sites located both in urban (Milano, Torino, and Roma) and peri-urban areas (Appia Park, Castel Porziano, and Castel Volturno) were selected. Among the six sites, Roma, Castel Porziano, and Castel Volturno are affected by the parasite Toumeyella parvicornis. The time series was analysed using the products available in Google Earth Engine. To explore and characterise long-term vegetation dynamics, the time series was analysed using a multistep processing chain based on the (i) normalisation of the satellite ti...

For this study, two commercial varieties of industrial hemp with low tetrahydrocannabinol (THC) content were used to test its reintroduction chance in the study area and to evaluate its response in terms of yield with respect to the soil and drought conditions of the area. During the vegetative period, non-invasive measures of the soil’s water status were performed using Watermark probes and ground penetrating radar. In addition, hemp crops vigour monitoring was performed by means of Sentinel 2 multispectral optical remote sensing data. In the absence of precipitation and/or irrigation, and with high consumption of soil water by the hemp crop due to evapotranspiration, the crop has completed its cycle thanks to its resistance to water stress conditions. From the soil water and satellite monitoring resul...

In this study, a calibration procedure was applied to estimate SM based on the integration of in situ and airborne thermal remote sensing data. To this aim, on April 2018, two airborne campaigns were carried out with the TASI-600 multispectral thermal sensor on the Petacciato (Molise, Italy) area. Simultaneously, soil samples were collected in different agricultural fields of the study area to determine their moisture content and the granulometric composition. A WorldView 2 high-resolution visible-near infrared (VNIR) multispectral satellite image was acquired to calculate the albedo of the study area to be used together with the TASI images for the estimation of the apparent thermal inertia (ATI). Results show a good correlation (R2 = 0.62) between the estimated ATI and the SM of the soil samples ...

Groundwater resources, which are exposed to overexploitation and pollution at regional and local ... more Groundwater resources, which are exposed to overexploitation and pollution at regional and local levels, may take benefit from fast, nonintrusive, and inexpensive monitoring methods based on electromagnetic techniques. In fact, the available technologies can help to improve management and protection of the aquifers. This chapter deals with the role of electromagnetic sensing techniques in water monitoring with a specific focus to pollution surveys in groundwater bodies. Being sensitive to the presence of water in the subsoil and its electrical conductivity, which in turn depends on the ionic content, the electromagnetic sensing techniques are useful tools for groundwater identification and soil quality assessment. In fact, these sensing techniques offer advantages such as quickness, nonintrusivity, and the possibility of investigating large areas at reasonable costs. However, the appropriate use of these techniques implies an adequate knowledge of their working principles as well as of their on field application procedures, which mainly depend on the survey aim and the geological and logistic conditions of the site. This chapter also discusses the uncertainty in the interpretation of results, which is due to the fact that the electromagnetic sensing techniques are based on indirect inspections. Several strategies can be exploited to reduce ambiguity of results, such as the integration of different electromagnetic techniques and the comparison between field data and those provided by laboratory experiments. These issues are herein addressed through practical examples concerning two study cases, one referred to a site located in Serbia-Herzegovina and one located in Italy. In particular, we illustrate the physical concepts, the operative aspects, the data processing, and the integration of results concerning the following measurement techniques: electrical resistivity tomography (ERT), ground-penetrating radar (GPR), time-domain-induced polarization (time domain IP), and self-potential method (SP). The two study cases concerns an industrial site and a large waste dump structure. These sites represent specific examples of soil monitoring and have been selected in order to evaluate the performance of the proposed techniques. For each site, we provide a description of the survey results accounting for geological evidences, logistic constraints, and physical limitation of the used techniques. Finally, we highlight the advantages offered by a cooperative use of different techniques and suggest strategies to overcome intrinsic limitations of each one of the considered survey methods.

In fact, an effective use of irrigation water for a sustainable agriculture helps to cut irrigation cost and the exploitation of technologies for water resource monitoring and management can help to achieve this objective. The work has regarded a flat experimental vegetable area of about 1000 m2 with the bean crop (Phaseolus vulgaris L), which was an subdivided in two adjacent plots of land five meters distant each from other. From sowing and for the whole cultural cycle, irrigation monitoring was performed by using non-invasive surveys, based on measurements of physical properties of the soil, as the dielectric constant and the electrical resistivity. A drip irrigation system was used with the water pumped by a nearby water reserve, represented by a small artificial lake, but a diff...

However, despite of its large number of successful cases of application, the use of geophysics is still often not considered; this due to different reasons as: the poor knowledge of the potential performances; the difficulties in the practical implementation; the cost limitations. In this work, an integrated study of non-invasive (geoelectrical) and direct surveys is described, aimed at identifying a subsoil foundation where it possible to set up a watertight concrete structure able to protect the purifier of Senise, a little town in Basilicata Region (Southern Italy). The purifier, used by several villages, is located in a particularly dangerous hydrogeological position, as it is very close to the Sinni river, which has been obstructed from many years by the Monte Cotugno dam. During the rainiest periods, the river could flood the purifier, causing the drainage of waste waters in the Monte Cotu...

Such approach does not solve all the questions related to the interpretation of historical data (graphics, descriptions) useful for finding previous configurations of the building. The historical building structure and shape, as they appear at the present are often the final result of a stratification of different phases deeply connected with artistic and technological features of the age during which the building has been designed and realized. Stylistic features, building techniques and functional aspects change in time leaving often written traces in archive sources such as on the building masonry texture (sometimes hidden by plaster) or under the floor. In such situation the Non Destructive Testing investigations by means o...

Time-lapse acquisition allows us to monitor in real time the variation of resistivity values in the first layers of the subsoil, closely connected with variation of the water content and potentially associated to the reactivation of the landslide. A weather station installed in the test site gives information about the rainfall intensity and frequency and suggests the acquisition time interval. Resistivity trend analysis was carried out in different ways: at first acquiring many sets of data that were inverted by the software RES2DINV, in order to obtain a series of ERT representative of the resistivity distribution in the subsoil during different periods of the year; then, considering resistivity data coupled with TDR ones and rainfall, realizing a statistical study in the time and space. Statistical study has been made by using a MATLAB script specifically created for this work. The installed system and the results are presented.
