SUMMARY:Micro-scale evolution of pore water characteristics in unsaturated sand under triaxial compression
DESCRIPTION:On Monday\, June 8\, a seminar titled “Micro-scale evolution of pore water characteristics in unsaturated sand under triaxial compression” will be held in Fassò Room (Building 4A) at 11:00 CET.\nThe seminar will be given by Ryunosuke Kido\, Associate Professor at Graduate School of Advanced Science and Engineering\, Hiroshima University. \nAbstract\nUnsaturated soil consists of granular particles and pore fluids (liquid and gas)\, and understanding its behavior requires clarifying the relationship between microscale phenomena and macroscale responses to better understand and predict the failure of earth structures and slopes. My research focuses on microscale phenomena in unsaturated soils that cannot be captured using conventional techniques. The objective is to visualize these invisible processes during laboratory testing through X-ray micro-computed tomography (CT) and advanced image analysis. In this seminar\, I will introduce the microscale evolution of pore water characteristics in unsaturated sand during triaxial compression\, with a particular focus on water retention states\, the spatial distribution of liquid bridges\, and the curvature of air–water interfaces. These observations provide new insights into the mechanisms governing the deviatoric stress responses observed in triaxial compression tests. \nBio-sketch\nDr. Ryunosuke Kido is an Associate Professor in the Graduate School of Advanced Science and Engineering\, Civil and Environmental Engineering Program at Hiroshima University\, Japan. He received his Doctor of Engineering from Kyoto University in 2019. During his doctoral studies\, he was awarded a Research Fellowship for Young Scientists by the Japan Society for the Promotion of Science (JSPS). Following the completion of his doctorate\, he served as an Assistant Professor at Kyoto University before joining Hiroshima University as an Associate Professor in 2024. In 2023\, he spent 10 months as a visiting scholar at Université Grenoble Alpes in France.

SUMMARY:Wonderful World of SPE (Solid Particle Erosion) and Challenges in Erosion Testing and Modeling
DESCRIPTION:On Tuesday\, June 16\, a seminar titled “Wonderful World of SPE (Solid Particle Erosion) and Challenges in Erosion Testing and Modeling” will be held in Grandori Room (Building 4) at 11:00 CET.\nThe seminar will be given by Prof. Siamack A. Shirazi\, Director\, Erosion/Corrosion Research Center\, The University of Tulsa.\n \nAbstract\nSolid particles entrained in fluids can impact pipelines and equipment causing wear and material removal.  In addition to interaction of particles with the carrier fluids\, particles interaction with solid materials makes this process highly complex and produces effects that are interesting and yet important to predict for practical engineering applications.  Solid particle erosion of pipeline and equipment depends on many parameters that can be categorized into three interacting components or elements:  One element is solid particles themselves that vary in shape\, size\, hardness and density.  Another important element is the materials characteristics such as hardness of materials\, ductility\, density\, and wear characteristics.  The last and certainty not the least is the carrier fluid properties and complexity of the flow regimes.  Interaction between these three elements are the most difficult to understand and model especially in multiphase gas-liquid-particle flows. Fluids and their interactions with solid particles add another order of magnitude in complexity for the prediction of solid particle erosion.\n\nBio-sketch\nSiamack A. Shirazi is a Professor of Mechanical Engineering and the Director of the Erosion/ Corrosion Research Center (E/CRC) at The University of Tulsa (TU). He is also the Director and Co-Founder of the TU Sand Management Projects (TUSMP). Over his distinguished career\, Professor Shirazi has contributed to more than 770 professional outputs\, including peer-reviewed publications\, conference papers\, technical conference and invited presentations. Over the past 36 years at TU\, Professor Shirazi’s teaching and research have significantly advanced the state of the art in erosion mitigation for oil and gas\, mining\, and renewable energy applications. He is internationally recognized through the sponsorship of his research programs\, his extensive publication record\, and the delivery of short courses worldwide. Dr. Shirazi\, together with his students and colleagues at E/CRC\, has developed widely adopted models for predicting erosion rates and threshold velocities. These methods are implemented in the software package SPPS (Sand Production Pipe Saver)\, also known as the “Tulsa Model\,” which is extensively used by practicing engineers for facility design\, re-design\, and equipment sizing. As a result of contributions\, Professor Shirazi has received numerous prestigious honors\, including the NACE (AMPP) Technical Achievement Award (2013)\, ASME Fellow (2008)\, NACE Fellow (2015)\, the ASME FED Moody Best Paper Award (2017)\, the SPE International Projects\, Facilities\, and Construction Award (2018)\, the ASME Petroleum Fluids Engineering Award (2019)\, the University of Tulsa Best Researcher Award (2023)\, and the SPE International Distinguished Member Award (2025).

SUMMARY:Shallow mixing interfaces between streams of unequal densities and their relevance for understanding mixing downstream of river confluences
DESCRIPTION:On Monday\, June 22\, a seminar titled “Shallow mixing interfaces between streams of unequal densities and their relevance for understanding mixing downstream of river confluences” will be held in Grandori Room (Building 4) at 11:00 CET. \nThe seminar will be given by George Constantinescu\, Professor in the Civil and Environmental Engineering Department at the University of Iowa. \nAbstract \nAs opposed to the case of shallow mixing layers forming between parallel streams of unequal velocities and equal densities\, the spatial development of the mixing interface between two parallel streams of unequal velocities and sufficiently large density contrast is controlled by the formation of a spatially developing\, lock-exchange-like flow in transverse planes. Eddy-resolving numerical simulations conducted in a wide and very long channel are used to investigate the mean flow structure and the effects of the lock-exchange-like flow and the associated coherent structures (e.g.\, streamwise-oriented vortical cells along the interface separating the regions containing heavier and lighter fluids) on mixing and the capacity of the flow to entrain sediment from the channel bed. These results are contrasted with the limiting case of shallow mixing layers with no density contrast where the dynamics of the quasi-two-dimensional Kelvin–Helmholtz vortices controls the structure and streamwise development of the mixing layer. These results are then used to explain how mixing is affected by density contrast at natural river confluences.  Using field measurements of the mean temperature at a small river confluence\, we show that accounting for stratification effects is critical for eddy-resolving simulations to accurately capture the mean temperature distribution downstream of the confluence apex. We then show that a temperature contrast of only couple of degree Celsius can have a large effect on the position and structure of the mixing interface at one of the largest river confluences in the world. For both confluent flows over a flat bed and over natural bathymetry\, density contrast between the incoming flow enhances mixing. Most of this mixing takes place beneath the free surface and is driven by coherent structures induced by stratification effects. \nBio-sketch \nDr. Constantinescu is a Professor in the Civil and Environmental Engineering Department at the University of Iowa. Dr. Constantinescu got his Ph.D. at the University of Iowa in 1998. Following this\, he occupied various research positions at Arizona State University and at the Center for Turbulence Research and the Center for Integrated Turbulence Simulations at Stanford University where he worked on the development of novel numerical algorithms for viscous flows\, Detached Eddy Simulation and computational aero-acoustics. He then joined the University of Iowa as an Assistant Professor in 2004. His research program is based on the use of eddy-resolving simulations to understand the physics of several important classes of environmental and geo-physical flows. Dr. Constantinescu’s current research focuses on turbulence and transport in rivers and lakes\, stratified flows\, shallow flows\, eco-hydraulics\, numerical modeling of floods and dam break waves of non-Newtonian fluids and flow in porous media. \n

SUMMARY:Seismic Wave Propagation in Complex Geological Domains: From Site Effects in Earthquakes to Diffuse Fields in Passive Seismology
DESCRIPTION:Within the PhD course on Elastic Wave Propagation with applications to Earthquake Engineering at Politecnico di Milano\, Prof. Francisco José Sánchez-Sesma\, Instituto de Ingeniería\, UNAM México\, will deliver a lecture on Seismic Wave Propagation in Complex Geological Domains: From Site Effects in Earthquakes to Diffuse Fields in Passive Seismology. \n  \n\nThe lecture will be delivered on June 22\, 2026\, at 16:00 (Italian time) in the Webex personal room: politecnicomilano.webex.com/meet/roberto.paolucci\nThis will be a repetition of the Joyner Memorial Lecture\, awarded jointly by the Earthquake Engineering Research Institute (EERI) and the Seismological Society of America (SSA)\, which recognizes outstanding individuals working at the intersection of earthquake science and engineering\, whether it involves contributions from earthquake science to earthquake engineering\, or from earthquake engineering to earthquake science. For 20 years\, these distinguished speakers have contributed to building codes\, seismic design guidelines\, probabilistic seismic hazard analysis\, and the characterization of site effects. Francisco José Sánchez-Sesma of the Universidad Nacional Autónoma de México (UNAM) delivered the 2026 Joyner Lecture at the SSA Annual Meeting in Pasadena\, CA\, and will do so again at the 13NCEE in Portland\, OR.\n\nAbstract\nThis lecture emerges from decades of research on seismic waves in complex geological media to assess ground motion\, from strong shaking to weak ambient vibrations such as microtremors and seismic noise. It is dedicated to William B. Joyner\, who bridged the gap between seismologists and engineers to achieve an earthquake-resilient society. Personally\, the 1985 Michoacán earthquake (Mw 8.1)\, which caused catastrophic damage in Mexico City\, was a key motivation. The Random Vibration Theory\, reformulated by Boore and Joyner\, helped us to craft the Mexico City building code\, which incorporated the Fourier spectrum as a design concept. Seismic hazard is a big puzzle; we take little pieces and try to solve each one. The Indirect Boundary Element Method (IBEM) enabled the study of the seismic response of topographic features and alluvial valleys to educate the intuition. The need for a geomorphological description is evident. Diffuse fields allowed us to establish the exact retrieval of Green’s functions from noise cross-correlations. This leads to a theory for the H/V spectral ratio to model ambient seismic noise measurements and infer subsurface layered structures. However\, including lateral irregularity is a major challenge. Preliminary results suggest it is possible to spot\, from H/V results\, zones that may trap energy in earthquakes.

SUMMARY:The vadose zone: a multifaceted perspective
DESCRIPTION:On Thursday\, June 25\, two seminars will be held in Grandori Room (Building 4) at 10:30 CET.\n\nThe first seminar will be given by Anna Dabudyk\, ITES Strasbourg Institute of Earth and Environment\, and is titled: Optimization of Monte Carlo simulations for physically-based groundwater recharge modelling: convergence\, sensitivity analysis and spatial upscaling.\n\nIt will also be possible to follow them online at the following link: https://politecnicomilano.webex.com/meet/aronne.delloca\n\nAbstract\nPhysically-based integrated hydrological models have become essential tools to inform quantitative management at the catchment scale. Recharge is a key process that is either computed internally or computed externally and then read as an input. In both cases\, a high level of uncertainty is expected as no real measurement of recharge are available.\nIn this work\, we use a chain of physically-based models comprising a Land Surface Model for groundwater recharge and a hydrological model that couples surface and subsurface flow processes. The main goal is to assess the impact of anthropogenic withdrawals on low flows and provide a rigorous quantification of uncertainties for both piezometric level and surface discharge.\nComputing groundwater recharge using a physically-based LSM model is a rather parameter intensive approach. To quantify the uncertainties\, this model uses a Monte Carlo framework to randomly sample 178 parameters per simulation. We first established that a minimum of 3\,000 simulations was required for convergence. Next\, we conducted a sensitivity analysis which revealed that uncertainties related to parameters are more significant than those related to meteorological forcing.\nOur next step is to focus on model efficiency. Using clustering methods\, we intent to select relevant pixels to compute groundwater recharge before upscaling to the entire catchment. This is a critical step\, as the groundwater recharge is then used as input data for the hydrological model\, for which computation times are significantly more challenging.\n\nBio-sketch \nAnna Dabudyk is a PhD student in hydrology at ITES (Strasbourg Institute of Earth and Environment). Her research focuses on catchment-scale quantitative hydrology\, using numerical modelling and statistical approaches to evaluate simulation reliability and quantify uncertainty. The main goal of her work is to understand the relationship between anthropogenic withdrawals and surface and groundwater water dynamics. Her work aims to bridge the gap between complex hydrological modelling and practical decision-making by providing uncertainty-aware numerical solutions for water management. \n\nThe second seminar will be given by Tomás Aquino\, IDAEA Spanish National Research Council institute\, Barcelona\, and is titled: From geometry to velocity: How medium structure and water saturation shape global flow statistics.\n \n\nAbstract\nSubsurface flows exhibit rich structure across multiple scales due to complex medium geometry. In the vadose zone\, i.e.\, the partially-saturated region that acts as a reactive filter for nutrients and contaminants\, flow heterogeneity is further enhanced by the simultaneous presence of air and water. Understanding\, quantifying\, and predicting transport and reaction in such systems requires models that can be parameterized based on incomplete information about the pore-scale structure and saturation\, which are typically known only to a limited extent.\nOver the last few decades\, stochastic models have gained in popularity as useful and elegant tools to fill this role. In addition to the classical inverse problem\, where Monte Carlo type methods are traditionally employed to quantify uncertainty\, recent stochastic transport and mixing models rely on statistical descriptions of the underlying flow field to make deterministic predictions of macroscopic quantities\, such as breakthrough curves and dispersion\, at larger scales. These methods typically rely on the probability of finding a certain velocity value anywhere in the domain together with a characteristic correlation length\, without need for detailed knowledge of the spatial structure. Despite their success\, the predictive power of such models remains limited by our inability to connect the statistics of geometric features\, such as pore throat widths\, to flow statistics. Indeed\, current mean field theories fail to capture the flow statistics even in simple disordered media.\nIn the first part of this talk\, I will discuss a new theory of flow statistics for saturated\, disordered media\, which employs a pore network description to connect flow distributions to macroscopic metrics like the porosity and the coeMicient of variation of pore throat widths. I will show that this theory performs very well for simple model porous media in two dimensions\, composed of disordered arrays of circular obstacles. In the second part of the talk\, I will discuss how flow statistics models can be extended to partially saturated conditions.\n\nBio-sketch\nTomás Aquino is a Researcher at the IDAEA\, a Spanish National Research Council institute in Barcelona dedicated to environmental sciences. He obtained his undergraduate and MSc degrees in Physics from the University of Lisbon\, Portugal\, where he is originally from\, and his PhD from the University of Notre Dame\, IN\, USA. He is the recipient of the ongoing ERC Starting Grant Uplift\, which is dedicated to advancing our understanding of flow\, transport\, mixing and reaction in partially saturated porous media across scales.

SUMMARY:Active dynamics of epithelial tissues
DESCRIPTION:On Thursday\, June 25\, a seminar titled “Active dynamics of epithelial tissues” will be held in Grandori Room (Building 4) at 14:00 CET. \nThe seminar will be given by Prof. Alexandre Kabla\, University of Cambridge. \nAbstract \nEpithelial tissues play a crucial role during embryonic development and in adult organisms\, forming essential physiological barriers within the body. These tissues frequently undergo and even instigate significant deformations while maintaining mechanical integrity. This presentation examines the autonomous force-generating behaviours of epithelial tissues and their mechanical consequences\, emphasizing theoretical and computational modelling strategies. Experimental investigations of in vitro MDCK cell monolayers reveal spontaneous contractility that generates tissue-scale tension and induces curling at free edges\, behaviours absent in isolated cells but emergent at the collective level. Epithelial tissues also continuously remodel through cell neighbour exchanges\, particularly during embryonic morphogenesis when coordinated cell rearrangements drive large-scale tissue flows. The interplay between active force generation and passive mechanical response determines the rate and spatial organization of these processes. Through modelling\, we investigate how individual cell rheology\, active contractility\, and mechanical coupling give rise to tissue-scale behaviours. Our findings reveal that mechanical coupling amplifies both internal and external mechanical signals\, creating sensitivity to stress states and boundary conditions that cannot be predicted from single-cell properties alone. \nBio-sketch \nProfessor Alexandre is a professor of mechanobiology in the Engineering Department. He trained as a physicist and computer scientist. His early research focused on the mechanics of sandcastles and liquid foams. He then progressively drifted towards fibrous materials\, and later to biological tissues and cell mechanics in general. \nHis group’s research focuses on the mechanobiology of tissues. They use numerical and analytical modelling\, as well as experimentation\, to study how cell assemblies respond to forces and control their mechanical properties\, as well as how active processes such as cell migration lead to tissue morphogenesis. \nHis research is collaborative and interdisciplinary. From a technical perspective\, the group has expertise in soft matter physics\, rheology\, mechanical characterisation of materials\, microfluidics\, and scientific software engineering. \n
