Studio e monitoraggio dei processi idrologici

Scheme of the HYDROMON project. L'IRPI è da molti anni impegnato nel monitoraggio di variabili idrologiche (umidità del suolo, pioggia, portata e velocità dei corsi d'acqua) che è risultato fondamentale per la rappresentazione del processo di formazione del deflusso e quindi per lo studio delle piene e delle ...

Preventive evaluation of land instability hazards

project-vapit-evidenza The urbanisation of seismically active areas, coupled with the ongoing change in climate patterns, require a shift in the approaches to land/infrastructure instability hazard assessment and risk reduction. This is particularly relevant in seismically active regions where the recurrent damage from landsliding, subsidence and ground deformations can be widespread. Geotechnical investigations and in situ monitoring of land prone to instability are ...

Hydrological monitoring and prediction of shallow landslides through remote sensing observations

project-LANDHYDRO-evidenza Rainfall-induced shallow landslides and floods are the most common and dangerous natural hazards, mainly due to their high temporal frequency, which causes fatalities and high economic damage worldwide. Climate changes will exacerbate this critical framework since an increase in extreme weather events is ...

A new independent GLOBAL rainfall product from ASCAT soil moisture observations through SM2RAIN

project-EUMETSAT_GLOBAL_SM2RAIN-evidenza Accurate rainfall estimates are of paramount importance as rainfall plays a key-role in many fields as, to cite a few, natural hazard assessment (floods and landslides), drought management, weather forecasting, agriculture and diseases prevention. State-of-the-art rainfall products obtained by satellites are often the only way for measuring rainfall in remote areas of the ...

What is the origin of the large Isidis Planitia, on Mars?

Focus-mars-p1-evidenza The characterization of an impact crater requires an understanding of the impact phenomena, considering the properties of the materials involved in the impact. The size and energy of the projectile control the width and depth of the crater. Related to impact craters is the formation of mass concentrations, or mascons, which produce intense positive gravity anomalies. One of the largest mascons is in the Isidis Planitia, Mars.Using the ...

Detecting rainfall from the bottom up

sm2rain-evidenza-1 SM2RAIN is an innovative system for the estimation of the rainfall, based on measurements of the soil water content. SM2RAIN considers the soil as a natural rain gauge, and by measuring temporal variations of the soil water content, it estimates the rainfall falling on the soil, adopting a “bottom up” approach. Technically, SM2RAIN relies on the inversion of the soil water balance equation that computes the repartition of rainfall in ...

Radar remote sensing techniques for the detection and measurements of ground surface deformations

DInSAR-in_evidenza- Space-borne radar interferometry or DInSAR (Differential Interferometric Synthetic Aperture Radar) is one of the latest techniques used for the detection and measurement of ground surface deformations caused by natural and / or man-made events. The DInSAR technique has been successfully used in the measurement of seismic deformations and of the effects of subsidence, unstable slopes and inflation of magma in volcanoes. The growth of space ...

Methodology for the estimation of environmental risk indicators, using satellite remote sensing techniques

project-mirasat-evidenza EPSILON Italia, the leader of the partnership proposing the project, is a SME, located in Calabria, specializing in the delivery of advanced services for the protection and management of natural resources, with a high standard of quality and technological content. The SME is also actively involved in the development and implementation of new technologies and in R&D activities conducted both in their own and in partnership with universities ...

Threedimensional Displacement Analysis

prodotti-servizi-3da-evidenza The 3DA software is a new procedure that allows retrieving in near-real-time 3D surface deformation models starting from data acquired via robotized total stations or others system that acquire the surface displacements. The measurements are first pre-processed and then implemented on 3D maps that include vector arrows representative of the intensities and of the real directions of motion in a given system of coordinates. The 3D surface ...

STSE Water Cycle Multi-mission Observation Strategy for the Mediterranean

ESA_WACMOS_MED_IMMEV Monitoring the water cycle from satellite observations is one of the major goals of the EO community and closing the water budget has been a long-standing objective of international programs. After years of hard work, calibrating satellite data, improving inversion techniques, and facilitating the coherency of retrievals, it is admitted that the water cycle budget can now be ...
