OUR SERVICES
Thanks to many years of experience gained in the academic field, today it is possible to use the avant-garde in in 3D modeling to improve all your design and prevention phases, up to the quantitative risk analysis (QRA) of civil works, infrastructures and territorial areas of different scales.
3D Rockfall
Hy-STONE: an advanced tool to understand the phenomenon and protect the territory
Hy-STONE
The Hy-STONE Software used for rockfall analysis allows the execution of "physically based" 3D models with the following characteristics: Read More
3D Geotechnical Modeling
We bring the geotechnical calculation to a more advanced level
Static and dynamic analysis
The analysis of the construction phases. Reproducing the interaction of lands and three-dimensional structures, the models that we implement allow us to represent and analyze in a faithful way the gradual construction of the works, the realization of the excavations and surveys, the installation / removal of temporary works up to the completion of the final works.

Reliability and security margins. This representation of reality allows to reduce the uncertainty related to the calculation of the analyzes and of the design safety margins.
Even monitoring can finally measure the distance of reality from calculation forecasts free from the uncertainty of two-dimensional geometric representations.
Reduction of construction costs and better allocation of resources. The design and construction solutions can be optimized on the basis of less redundant and costly safety margins that make it possible to better allocate resources in favor of an increase in the performance of the work, its features and of its functionality.
3D Hydrogeological modeling
Advanced 3D modeling for the management of present and future water resources
Models of hydrogeology, thermal potential and heat transport
The management of groundwater resources requires the study of the chemical and physical characteristics of the aquifers, their balance and the existing interactions with the surface waters and the human activities. Read More
EG4Risk provides an expertise in the fields of hydrogeophysics and hydrogeology with skills in the characterization of saturated and unsaturated sites through geophysical surveys, well’s measurements, sampling and direct and indirect parameter estimation. EG4Risk has experience in the geostatistical analysis of chemical-physical data and pollutants, in the reconstruction of three-dimensional conceptual geological models using modeling tools, in the generation of numerical models for the study of the outflow and transport phenomena of the heat and the mass. EG4Risk has produced: hydrogeological models and models of the heat potential and of the thermal transfer at a local and regional scale, considering the interactions between the surface and underground waters, between aquifers and structures and infrastructures, between land use and the aquifers.
3D landslides modeling
Ten years experience in the characterization and modeling of the slope instabilities
Dependence on the geomorphology, geology and atmospheric agents
Several instability phenomena can be characterized by a high mobility, both for the presence of a high water content, and for high energy or to the action of mechanisms that favor a decrease in the resistance of the materials involved. Read More
EG4Risk participants have considerable experience in modeling such phenomena, both for small events (debris flows and debris avalanches) and for large rock and ice avalanches. The models, realized both in national and international contexts, allowed the preparation of the hazard maps and of the quantitative estimate of the risk, the support to the drafting of Civil Protection Plans, and the design of containment structures from the geometric point of view (overcoming) and from the structural sizing (in static and dynamic conditions). The collaboration with the FEAT company also offers the possibility to develop advanced 3D modeling in different topographical, environmental and structural conditions.
Reliefs and Monitoring
Direct and remote acquisition of topographic, hydrological, hydrogeological, geophysical and geotechnical data
Implement the dataset to support analysis, modeling and forecasting
The prediction of slope instability events implies the need to identify: The availability of the monitoring tools and data, methods of analysis and modeling is essential in these forecasting phases. EG4Risk has a long experience in the design of monitoring networks, data collection, analysis and forecasting modeling for the triggering of landslides from intense meteoric events, snow fusion, earthquakes and from the human activities. EG4Risk is expert in the analysis of data from monitoring networks and remote acquisition of topographic, hydrological, hydrogeological and geotechnical variables. In particular, EG4Risk performed data analysis activities detected by laser scanners, ground-based interferometric synthetic aperture radar (GB-InSAR) and by satellite, with development of approaches for the analysis and use of such data in classifications of the activity status and prediction of evolution in terms of expected displacements and evolution by rapid collapse. EG4Risk staff has developed such activities for both superficial and deep instability, in very different environmental conditions, for natural and artificial slopes, in mining excavations, in soil and rocks, for some of the landslides considered to be among the most dangerous in Italy. In these activities, trigger and warning thresholds have been defined to be used in Early Warning systems and for the management of civil protection plans.

Probabilistic study of seismic hazard
Estimation of the expected shaking in a given area over a given period of time
The probabilistic study of seismicity is carried out according to a Cornell approach (Cornell, 1968):
- Phase 1: Identification and description of the seismic sources, represented and defined through seismogenic zones.
- Phase 2: Definition of the magnitude recurrence patterns for each source through magnitude-frequency relationships (Gutenberg-Richter)
-Phase 3: Estimation of the probability to exceed a certain ground shaking, through Ground Motion Prediction Equation
-Phase 4: Calculation of the hazard curve and response spectrum derived from logic tree analysis
- Phase 5: Introduction of the recurrence component, considering different return times
