Following on from the development of the Mjolnir triaxial deformation rig (Butler et al., 2020), we present an upscaled design: Heitt Mjolnir, covering a wider temperature range and larger sample volume while operating at similar pressure, enabling a wide range of time-resolved investigations. This device is designed to characterise coupled hydraulic, chemical and mechanical processes, occurring at various temperatures, from the µm to the centimetre scale in cylindrical samples of 10 mm diameter and 20 mm length. Heitt Mjolnir can simultaneously reach confining pressures of ≤30 MPa (hydraulic), 500 MPa of axial stress while the sample’s pore fluid pressure is controlled in a dedicated fluid channel and can reach 30 MPa. This apparatus has an internal heating system and is able to reach temperatures of 573 K in the sample with a minimal vertical thermal gradient of <0.5 K/mm. This portable and modular device has been successfully deployed in operando studies at TOMCAT (SLS) and I12 JEEP (DLS) beamlines for 4D X-ray microtomography with scan intervals of a few minutes. Heitt Mjolnir allows the 4D characterisation of low-grade metamorphism, fluid-rock interaction and deformation processes. It enables spatially and temporally resolved fluid-rock interaction studies at a wide range of conditions and, by covering most geological reservoirs, will be particularly valuable for geothermal, carbonation or subsurface gas storage research.

International audience; The LHC-forward experiment (LHCf), located at the Large Hadron Collider (LHC), is designed tomeasure the production cross section of neutral particles in the very-forward region, covering thepseudorapidity region above 8.4 (up to zero-degree particles). By measuring the very-forwardparticle production rates at the highest energy possible at an accelerator, LHCf will providefundamental informations to improve phenomenological hadronic interaction models used in thesimulation of air-showers induced by ultra-high-energy cosmic rays in the atmosphere. Theexperiment consists of two small independent detectors placed 140 metres away from the ATLASinteraction point (IP1), on opposite sides. Each detector is made of two sampling and positionsensitive calorimeters.This contribution will focus on the Run II physics results of LHCf in proton-proton collisions at 13TeV. At first the photon energy spectrum will be presented and compared with the predictions ofseveral hadronic interaction models. The advantages of the ATLAS-LHCf combined analysis willthen be discussed and the preliminary spectrum of very-forward photons produced in diffractivecollisions (tagged by ATLAS) will be shown together with models predictions. The preliminaryFeynman-x and transverse momentum spectrum of $\pi^0$, and the Feynman-x spectrum of $\eta$ will alsobe presented. Photons and $\pi^0$ production cross section provides important information about theelectromagnetic component of an air-shower, while $\eta$ measurements give the possibility to probethe strange-quark related contribution. Finally, the neutron energy spectrum measured in severalpseudorapidity regions will be shown and compared with the predictions of various hadronicinteraction models. From these measurements the average inelasticity of the collisions, whichstrongly affects the development of an air-shower, has also been extracted.

Here, faults and related fracture networks can compromise sealing by providing an interconnected pathway for injected fluids to reach overlying aquifers or even the surface or sea bottom. In this work, we apply an integrated workflow [1] that, combining single fracture stress-permeability laboratory measurements and detailed fault and fracture network outcrop data, builds permeability models of naturally faulted caprock formations for in situ stress conditions.</p><p>We focus our study on two-dimensional (2D) fault-related fracturing within caprock sequences cut by extensional faults. 2D data of fault and fracture networks were collected from an Upper Jurassic to Lower Cretaceous shale-dominated succession in the Konusdalen area (Nordenskioldland, Svalbard, Norway). The studied rock succession represents the regional caprock and seal for the reservoir of the nearby Longyearbyen CO<sub>2</sub> Lab. By digitising all the visible features over the images and then inputting them into the open-source toolbox FracPaQ [2], we obtain information about the fault and fracture networks. In particular, we study the variations in fracture size (i.e., length, height) and density distribution near and away from the fault zone(s), together with the connectivity of fractures within the network. These three parameters are fundamental to establish if the network provides permeable pathways. They also enable us to statistically reproduce and upscale a fracture network in a realistic way.</p><p>Combining laboratory single fracture stress-permeability measurements with outcrop fracture network data allow us to create an accurate coupled mechanical-hydromechanical model of the natural fracture network and to evaluate the effective permeability of a fault related fracture network. These results are also compared against analytical estimates of effective permeability [3]. With this workflow, we overcome the geometrical simplifications of synthetic fracture models, thus allowing us to establish representative stress-permeability relationships for fractured seals of geological CO2 storage.</p><p>Reference:&#160;[1] March et al., 2020, Preprint; [2] Healy et al., 2017, JSG; [3] Seavik & Nixon, 2017, WRR</p>

Abstract The conservation of historical buildings in Cairo represents a complex matter, influenced by several key factors such as the cultural context, the intrinsic features of a vast and heterogeneous architectural heritage and the environmental conditions. An Italian-Egyptian research group is working on the peculiarities of the monument conservation in old Cairo, concerning the material decay in relation to the anthropic and climatic factors and the pollution levels. Monument vulnerability levels strongly need to be identified and systematized to delineate adequate programs of control, management and intervention. One of the main topics developed is the study of the deterioration mechanisms of stone materials in medieval walls, connected to the capillary damp rising from the ground, common in Egypt, always accentuated by the combination with other factors. The research examines some historic buildings in different areas (El-Gamaleya, El Darb El Ahmar, Al Qarafah). The variety of materials has led to limiting the first phases of the study to the masonry materials, with special attention to the limestone blocks. The intersection of data collected on the field with those relating to underground water and environmental factors has allowed us to focus on some aspects of the problem. Some syntheses have been proposed on the main mechanisms affecting the studied material in situ and the necessary directions for further investigation have been identified. Our first results highlight the relationship existing between the environmental thermo-hygrometric excursions and the capillary water rising from the ground, which affect the evaporation speed, the imbibition levels and the crystallization of salts inside and on the rock surface. The studied rocks display intense weathering (decohesion, dissolution) due to a number of chemical and physical phenomena, responsible for a generalized decay of the mechanical properties of the original material. The observed widespread phenomena of carbonate sulphation also suggest the atmospheric contribution of particulate matter and polluting compounds. The mineralogical and physical characterization of the limestone allowed us to estimate its resistance to the decay processes.

Alessandri; V. Baiocchi; S. Del Pizzo; F. Di Ciaccio; M. Onori; M. F. Rolfo; S. Troisi;Abstract. Caves have been used by humans and animals for several thousand years until present but, at these time scales, their structures can rapidly change due to erosion and concretion processes. For this reason, the availability of precise 3D models improves the data quality and quantity allowing the reconstruction of their ancient appearance, structure and origin. However, caves are usually characterised by lack of light, high percentage of relative humidity, narrow spaces and complex morphology. Thus, quite often the traditional topographic instruments cannot be employed. In the La Sassa cave (Sonnino, Italy) a huge deposit ranging from Pleistocene to the Second World War has been found and stratigraphic evidence suggested that the shape of the cave and its entrance might have been different. In this paper, the fusion of the internal and external 3D photogrammetric models of the La Sassa, made to support the archaeological excavations, is presented, A Nikon camera with a fisheye lens and a smartphone camera have been used to survey the internal part of the cave, while an aerial drone has been employed for the external area. The two models have been georeferenced and scaled using GCPs acquired by a double frequency GNSS (GPS and GLONASS) receiver. A low-resolution DTM derived from a previous aerial laser scanning survey and the 3D models have been elaborated in CloudCompare environment to highlight the complete morphology of the cave and its surroundings.

Side weirs are particular structures used in hydraulic engineering for flow control in rivers and channels. In movable bed situations, the lateral discharge withdrawal can influence sediment transport processes causing an unexpected functioning of the weir; due to the possible changes in bed morphology, sediments from the main channel can be diverted in the evacuation channel as well. This paper summarizes the results of experimental analyses carried out to study these interactions for inclined weirs, under different hydraulic and geometric conditions. The results show the influence of weir’s length and inclination of the crest on the pattern of deposition and erosion zones in the main channel. The analysis of the experimental observations also confirm the validity of the De Marchi’s approach for modelling the behavior of inclined side weirs on movable beds. In addition, the predictive capability of a numerical method for estimating the diverted solid discharge from side weirs is tested. The comparison of observed and predicted sediment discharges outflowing from the lateral structure indicates the reliability of the tested method also for inclined side weirs.

In time, this expanded to become the most notable man-made landscape feature on the entire island. Mining operations are supported by a large array of workshops and facilities, scattered from the top of the mountain down to the seashore. They include large camps and mining villages hosting the workforce and their families. In this work, we present the results of a project to help mining company staff define triggers for an early warning system (EWS) for shallow landslides using meteorological forecasts and rain gauge measurements. This would help to mitigate the risk for the Grasberg mine and surrounding valleys of sudden detachment, routing and runout of shallow landslides.

A processing chain jointly employing Sentinel-1 and Sentinel-2 data is presented. It aims at monitoring changes in the status of the vegetation cover by integrating the three red-edge (RE) bands of Sentinel-2, at 20 m pixel spacing, with textural features calculated from the Interferometric Wide (IW) Ground Range Detected (GRD) product of Sentinel-1, available at 10 m pixel spacing. Hyper-sharpening on Sentinel-2 multispectral bands and modulation-based integration of Sentinel-1 SAR acquisitions are applied on a multitemporal dataset acquired before and after a recent fire event. New color-composite results of the proposed fusion procedure may be useful for visual inspection and analysis by experts in vegetation status monitoring.

Following on from the development of the Mjolnir triaxial deformation rig (Butler et al., 2020), we present an upscaled design: Heitt Mjolnir, covering a wider temperature range and larger sample volume while operating at similar pressure, enabling a wide range of time-resolved investigations. This device is designed to characterise coupled hydraulic, chemical and mechanical processes, occurring at various temperatures, from the µm to the centimetre scale in cylindrical samples of 10 mm diameter and 20 mm length. Heitt Mjolnir can simultaneously reach confining pressures of ≤30 MPa (hydraulic), 500 MPa of axial stress while the sample’s pore fluid pressure is controlled in a dedicated fluid channel and can reach 30 MPa. This apparatus has an internal heating system and is able to reach temperatures of 573 K in the sample with a minimal vertical thermal gradient of <0.5 K/mm. This portable and modular device has been successfully deployed in operando studies at TOMCAT (SLS) and I12 JEEP (DLS) beamlines for 4D X-ray microtomography with scan intervals of a few minutes. Heitt Mjolnir allows the 4D characterisation of low-grade metamorphism, fluid-rock interaction and deformation processes. It enables spatially and temporally resolved fluid-rock interaction studies at a wide range of conditions and, by covering most geological reservoirs, will be particularly valuable for geothermal, carbonation or subsurface gas storage research.

International audience; The LHC-forward experiment (LHCf), located at the Large Hadron Collider (LHC), is designed tomeasure the production cross section of neutral particles in the very-forward region, covering thepseudorapidity region above 8.4 (up to zero-degree particles). By measuring the very-forwardparticle production rates at the highest energy possible at an accelerator, LHCf will providefundamental informations to improve phenomenological hadronic interaction models used in thesimulation of air-showers induced by ultra-high-energy cosmic rays in the atmosphere. Theexperiment consists of two small independent detectors placed 140 metres away from the ATLASinteraction point (IP1), on opposite sides. Each detector is made of two sampling and positionsensitive calorimeters.This contribution will focus on the Run II physics results of LHCf in proton-proton collisions at 13TeV. At first the photon energy spectrum will be presented and compared with the predictions ofseveral hadronic interaction models. The advantages of the ATLAS-LHCf combined analysis willthen be discussed and the preliminary spectrum of very-forward photons produced in diffractivecollisions (tagged by ATLAS) will be shown together with models predictions. The preliminaryFeynman-x and transverse momentum spectrum of $\pi^0$, and the Feynman-x spectrum of $\eta$ will alsobe presented. Photons and $\pi^0$ production cross section provides important information about theelectromagnetic component of an air-shower, while $\eta$ measurements give the possibility to probethe strange-quark related contribution. Finally, the neutron energy spectrum measured in severalpseudorapidity regions will be shown and compared with the predictions of various hadronicinteraction models. From these measurements the average inelasticity of the collisions, whichstrongly affects the development of an air-shower, has also been extracted.

Here, faults and related fracture networks can compromise sealing by providing an interconnected pathway for injected fluids to reach overlying aquifers or even the surface or sea bottom. In this work, we apply an integrated workflow [1] that, combining single fracture stress-permeability laboratory measurements and detailed fault and fracture network outcrop data, builds permeability models of naturally faulted caprock formations for in situ stress conditions.</p><p>We focus our study on two-dimensional (2D) fault-related fracturing within caprock sequences cut by extensional faults. 2D data of fault and fracture networks were collected from an Upper Jurassic to Lower Cretaceous shale-dominated succession in the Konusdalen area (Nordenskioldland, Svalbard, Norway). The studied rock succession represents the regional caprock and seal for the reservoir of the nearby Longyearbyen CO<sub>2</sub> Lab. By digitising all the visible features over the images and then inputting them into the open-source toolbox FracPaQ [2], we obtain information about the fault and fracture networks. In particular, we study the variations in fracture size (i.e., length, height) and density distribution near and away from the fault zone(s), together with the connectivity of fractures within the network. These three parameters are fundamental to establish if the network provides permeable pathways. They also enable us to statistically reproduce and upscale a fracture network in a realistic way.</p><p>Combining laboratory single fracture stress-permeability measurements with outcrop fracture network data allow us to create an accurate coupled mechanical-hydromechanical model of the natural fracture network and to evaluate the effective permeability of a fault related fracture network. These results are also compared against analytical estimates of effective permeability [3]. With this workflow, we overcome the geometrical simplifications of synthetic fracture models, thus allowing us to establish representative stress-permeability relationships for fractured seals of geological CO2 storage.</p><p>Reference:&#160;[1] March et al., 2020, Preprint; [2] Healy et al., 2017, JSG; [3] Seavik & Nixon, 2017, WRR</p>

Abstract The conservation of historical buildings in Cairo represents a complex matter, influenced by several key factors such as the cultural context, the intrinsic features of a vast and heterogeneous architectural heritage and the environmental conditions. An Italian-Egyptian research group is working on the peculiarities of the monument conservation in old Cairo, concerning the material decay in relation to the anthropic and climatic factors and the pollution levels. Monument vulnerability levels strongly need to be identified and systematized to delineate adequate programs of control, management and intervention. One of the main topics developed is the study of the deterioration mechanisms of stone materials in medieval walls, connected to the capillary damp rising from the ground, common in Egypt, always accentuated by the combination with other factors. The research examines some historic buildings in different areas (El-Gamaleya, El Darb El Ahmar, Al Qarafah). The variety of materials has led to limiting the first phases of the study to the masonry materials, with special attention to the limestone blocks. The intersection of data collected on the field with those relating to underground water and environmental factors has allowed us to focus on some aspects of the problem. Some syntheses have been proposed on the main mechanisms affecting the studied material in situ and the necessary directions for further investigation have been identified. Our first results highlight the relationship existing between the environmental thermo-hygrometric excursions and the capillary water rising from the ground, which affect the evaporation speed, the imbibition levels and the crystallization of salts inside and on the rock surface. The studied rocks display intense weathering (decohesion, dissolution) due to a number of chemical and physical phenomena, responsible for a generalized decay of the mechanical properties of the original material. The observed widespread phenomena of carbonate sulphation also suggest the atmospheric contribution of particulate matter and polluting compounds. The mineralogical and physical characterization of the limestone allowed us to estimate its resistance to the decay processes.

Alessandri; V. Baiocchi; S. Del Pizzo; F. Di Ciaccio; M. Onori; M. F. Rolfo; S. Troisi;Abstract. Caves have been used by humans and animals for several thousand years until present but, at these time scales, their structures can rapidly change due to erosion and concretion processes. For this reason, the availability of precise 3D models improves the data quality and quantity allowing the reconstruction of their ancient appearance, structure and origin. However, caves are usually characterised by lack of light, high percentage of relative humidity, narrow spaces and complex morphology. Thus, quite often the traditional topographic instruments cannot be employed. In the La Sassa cave (Sonnino, Italy) a huge deposit ranging from Pleistocene to the Second World War has been found and stratigraphic evidence suggested that the shape of the cave and its entrance might have been different. In this paper, the fusion of the internal and external 3D photogrammetric models of the La Sassa, made to support the archaeological excavations, is presented, A Nikon camera with a fisheye lens and a smartphone camera have been used to survey the internal part of the cave, while an aerial drone has been employed for the external area. The two models have been georeferenced and scaled using GCPs acquired by a double frequency GNSS (GPS and GLONASS) receiver. A low-resolution DTM derived from a previous aerial laser scanning survey and the 3D models have been elaborated in CloudCompare environment to highlight the complete morphology of the cave and its surroundings.

Side weirs are particular structures used in hydraulic engineering for flow control in rivers and channels. In movable bed situations, the lateral discharge withdrawal can influence sediment transport processes causing an unexpected functioning of the weir; due to the possible changes in bed morphology, sediments from the main channel can be diverted in the evacuation channel as well. This paper summarizes the results of experimental analyses carried out to study these interactions for inclined weirs, under different hydraulic and geometric conditions. The results show the influence of weir’s length and inclination of the crest on the pattern of deposition and erosion zones in the main channel. The analysis of the experimental observations also confirm the validity of the De Marchi’s approach for modelling the behavior of inclined side weirs on movable beds. In addition, the predictive capability of a numerical method for estimating the diverted solid discharge from side weirs is tested. The comparison of observed and predicted sediment discharges outflowing from the lateral structure indicates the reliability of the tested method also for inclined side weirs.

In time, this expanded to become the most notable man-made landscape feature on the entire island. Mining operations are supported by a large array of workshops and facilities, scattered from the top of the mountain down to the seashore. They include large camps and mining villages hosting the workforce and their families. In this work, we present the results of a project to help mining company staff define triggers for an early warning system (EWS) for shallow landslides using meteorological forecasts and rain gauge measurements. This would help to mitigate the risk for the Grasberg mine and surrounding valleys of sudden detachment, routing and runout of shallow landslides. To achieve such a scope, the work has been split into three main tasks:

A processing chain jointly employing Sentinel-1 and Sentinel-2 data is presented. It aims at monitoring changes in the status of the vegetation cover by integrating the three red-edge (RE) bands of Sentinel-2, at 20 m pixel spacing, with textural features calculated from the Interferometric Wide (IW) Ground Range Detected (GRD) product of Sentinel-1, available at 10 m pixel spacing. Hyper-sharpening on Sentinel-2 multispectral bands and modulation-based integration of Sentinel-1 SAR acquisitions are applied on a multitemporal dataset acquired before and after a recent fire event. New color-composite results of the proposed fusion procedure may be useful for visual inspection and analysis by experts in vegetation status monitoring.
