Seismic Simultaneous Source Separation via Patchwise Sparse Representation

The concept of simultaneous source has recently become of interest in seismic exploration, due to its efficient or economic acquisition or both. The blended data overlapped between shot records are acquired in simultaneous source acquisition. Separating th ...

Locating transient disturbance sources and modelling their interaction with transmission lines

Gaspard Lugrin

This thesis deals with the application of electromagnetic time reversal to locating transient disturbance sources and the use of the asymptotic theory for the modelling of their interaction with transmission lines. We demonstrate that the time-of-arrival, ...

The role of mass-transport deposits and turbidites in shaping modern lacustrine deepwater channels

Nicolas Le Dantec

Subaquatic canyons are an important pathway for sediment transport into oceanic and lacustrine basins. Understanding the mechanisms governing their geomorphological evolution is a key to predict the sediment distribution patterns through these sediment con ...

Coupled inverse modeling of a controlled irrigation experiment using multiple hydro-geophysical data

Gabriele Manoli, Damiano Pasetto, Matteo Rossi

Geophysical surveys can provide useful, albeit indirect, information on vadose zone processes. However, the ability to provide a quantitative description of the subsurface hydrological phenomena requires to fully integrate geophysical data into hydrologica ...

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

Thomas Emmanuel Blum

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 ...

An iterative particle filter approach for coupled hydro-geophysical inversion of a controlled infiltration experiment

Gabriele Manoli, Damiano Pasetto, Matteo Rossi

The modeling of unsaturated groundwater flow is affected by a high degree of uncertainty related to both measurement and model errors. Geophysical methods such as Electrical Resistivity Tomography (ERT) can provide useful indirect information on the hydrol ...
