Full-wavefield modeling and reverse time migration of laser ultrasound data: A feasibility study

Laser ultrasound (LU) data acquired on cylindrical core samples effectively probe the physical properties of geologic materials. Although most LU analyses focus on estimating and inverting traveltimes of direct arrivals, it is important to recognize that L ...

Analysis of TBM tunnelling performance in faulted and highly fractured rocks

Erika Paltrinieri

The thesis focuses on the study of the performance of TBMs in highly jointed and faulted rocks. Despite the great production rates recorded in favourable ground conditions, the TBM advance can be significantly slowed down in limiting geological situations ...

A hydromechanical approach to assess CO2 injection-induced surface uplift and caprock deflection

Lyesse Laloui, Chao Li

This study focuses on the derivation of a semi-analytical approach for the evaluation of surface uplift and caprock deflection induced by underground injection of CO2. The adopted methodology includes the development of a mathematical model that incorporat ...

Uranium Isotopes Fingerprint Biotic Reduction

Rizlan Bernier-Latmani, Yuheng Wang, Malgorzata Alicja Stylo

Knowledge of paleo-redox conditions in the Earth's history provides a window into events that shaped the evolution of life on our planet. The role of microbial activity in paleo-redox processes remains unexplored due to the inability to discriminate biotic ...

Sediment dynamics in the subaquatic channel of the Rhone delta (Lake Geneva, France/Switzerland)

Nicolas Le Dantec

With its smaller size, well-known boundary conditions, and the availability of detailed bathymetric data, Lake Geneva's subaquatic canyon in the Rhone Delta is an excellent analogue to understand sedimentary processes in deep-water submarine channels. A mu ...

The Signature of Hillslope Aspects on the Hydrologic Response of Snow-Covered Catchments

Andrea Rinaldo, Michael Lehning, Bettina Schaefli, Francesco Comola, Gianluca Botter, Pierfrancesco Da Ronco

The hydrologic response of Alpine catchments embeds the geomorphologic signature of the dominant drivers influencing snowmelt runoff dynamics. The focus of this work is the role of aspect as the main control on incoming radiation. We investigate the link b ...

Flow and Temperature Dynamics in the Hydrologic Response of Alpine Catchments: Travel Time Formulation and Geomorphologic Signatures

Andrea Rinaldo, Michael Lehning, Bettina Schaefli, Francesco Comola

We present a travel time formulation of water and energy transport at sub-catchment scale. The derived equations are implemented in Alpine3D, a physically-based model of snow processes, which provides the necessary boundary conditions to perform hydro-ther ...
