Optimazation of marine sediments characterization via statistical analysis
The task of geotechnical site characterization includes defining the layout of ground units and establishing their relevant engineering properties. This is an activity in which uncertainties of different nature (inherent, ...
Seawater intrusion, transition zone dynamics and reactive mixing : example of Argentona coastal alluvial aquifer
Freshwater quality and availability in coastal areas are affected by seawater intrusion into coastal aquifers. While coastal water quality and coastal ecosystems can be significantly affected by pollutants discharged into ...
Advanced exploitation of Sentinel-1 data for supporting landslide risk analysis
Satellite Synthetic Aperture Radar Interferometry (InSAR) and Persistent Scatterer Interferometry (PSI) are now consolidated tools for ground movement detection and monitoring. Sentinel-1 (S1) is the first satellite providing ...
Estudio comparativo de métodos para la evaluación de la susceptibilidad del terreno a la formación de deslizamientos superficiales : aplicación al Pirineo Oriental
Human and economic losses caused by landslides have attracted the interest of the scientific community for the identification of the threatened areas and preventing their consequences. The goal of the landslide susceptibility ...
Hydrogeology of salt flats : the Salar de Atacama example
This thesis aims to advance the knowledge of the hydrogeological functioning of salt flats in order to achieve a sustainable management of their mineral resources and ecosystems. Salt flats are a major source of Li, B, I, ...
Advancing in the characterization of coastal aquifers : a multimethodological approach based on fiber optics distributed temperature sensing
Detailed characterization of coastal aquifers is essential for proper management of coastal groundwater resources, and coastal areas in general. Still, there is a general lack of systematic monitoring and detailed ...
Landslide and debris flow warning at regional scale. A real-time system using susceptibility mapping, radar rainfall and hydrometeorological thresholds
Rainfall triggered shallow slides and debris flows constitute a significant hazard that causes substantial economic losses and fatalities worldwide. Regional-scale risk mitigation for these processes is challenging. ...
Estudio numérico del ataque ácido por CO2 en cementos de pozos de petróleo sellados
In order to cope with the serious and urgent problem of global warming, it is imperative to reduce the impact of CO2 emissions in the atmosphere. One of the alternatives proposed involves the injection of the CO2 in deep ...
Ejecución de túneles en terreno deltaico mediante tuneladora EPB : el caso de la línea 9
The urban tunneling may generate significant problems. One of the main concerns is the unavoidable ground movements generated; before, during and after the tunneling operations. In this context, the objective of this Thesis ...
Multirate mass transfer and biofilm growth modeling in porous media
Reactive transport modeling is a methodological tool to study the coupled physical, chemical and biological processes in Earth system. It is complex not only because of the nature of the equations, but also because of the ...
Construction and post-construction performance of vertical breakwaters on soft soils : the Port of Barcelona case
The design and construction of vertical caisson breakwaters on soft soils represents a significant challenge for the engineering of marine structures. Past experience reveals that this type of structures is sometimes prone ...
Mixing and chemical reaction hotspots in saline-freshwater mixing zones
Seawater intrusion presents one of the most unique and ubiquitous groundwater problems in the field of hydrogeology. Its complex boundary conditions coupled with variable density flow results in non-uniform flow which lead ...
Hydraulic fills liquefaction : effect on quay stability
The starting point of this thesis is the failure of part of a quay wall under construction. The quay was divided in two phases, failure affected Phase 1 only. The failure and all the relevant associated information on quay ...
Modelling time-dependent plastic behaviour of geomaterials
Representing the time-dependent plastic behaviour of geomaterials is a critical issue in the correct application of tunnelling design techniques such as the convergence-confinement method or numerical modelling. Furthermore, ...
Hydrodynamics and geochemistry at multiple scales : characterizing preferential flow-paths and wormholes in evaporitic sediments
The characterization of evaporitic aquifers for a better understanding of hydrodynamics and geochemical processes is of great importance, especially in environments where both the sustainability of unique ecosystems and ...
A double-porosity formulation for the THM behaviour of bentonite-based materials
The thermo-hydro-mechanical (THM) behaviour of expansive clays has been extensively studied in the last decades due to the potential use of bentonites as components of engineered barrier systems (EBS) in deep geological ...
Granular flow characterisation towards an enhanced bulk feeder selection
In the packaging industry, a wide range of powders and bulk solids are handled in bagging equipment using different bulk feeding techniques. Quality of the packaging is critically affected by feeder performance, which is ...
Modelling fragmentation in rockfalls
The fragmentation process in rockfalls is a complex phenomenon that is not well understood and only a few rockfall simulation models consider it explicitly. Fragmentation significantly affects the evaluation of the hazard ...
Physical, geochemical and microbial parameters driving the improvement of water quality in managed aquifer recharge
Worldwide water demand has been increasing over time, mainly due to population growth and society development. In addition, climate change is causing a significant alteration of the periodicity and intensity of precipitation ...
T-H-M coupling with large advection in fractured rock masses using zero-thickness interface elements
The study of hydro-mechanical (HM) coupled problems in different areas of civil, environmental or petroleum engineering is common in literature, but the effect of a thermal field by means of the heat transport by a fluid ...
