Climent Pera, Natalia (Date of defense: 2016-10-17)
During the oil recovery a hole is drilled, the sandstone is left unsupported next to the cavity and disloged sand grains can enter the oil recovery system. This process is called sand production and several problems may ...
Vasconcellos, Ramon Barboza de (Date of defense: 2021-05-18)
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 ...
Sapriza Azuri, Gonzalo (Date of defense: 2013-12-20)
There is a growing concern about the combined effect of climate change and groundwater overexploitation on the availability of water resources in the Upper Guadiana basin (UppGb) in central Spain. General Circulation Models ...
Barra, Anna (Date of defense: 2022-04-22)
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 ...
Parera Morales, Ferran (Date of defense: 2020-01-27)
The understanding of soil behavior is the foundation where the geotechnical engineering is built on. Experimentation is essential to improve this comprehension, and then to be able to translate it into models, theories, ...
Del Val Alonso, Laura (Date of defense: 2020-06-03)
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 ...
Criollo Manjarrez, Rotman A. (Date of defense: 2019-03-08)
The conceptualisation of a groundwater system involves continuous monitoring and evaluation of a large number of parameters (e.g., hydraulic parameters). Regarding hydraulic properties of the aquifers, their quantification ...
Salami, Younes (Date of defense: 2017-01-11)
Au cours des dernières années, les analyses multi-échelles en mécanique des sols granulaires deviennent de plus en plus répandues. L’avantage de ce type d’approches réside dans leur capacité à établir un lien entre les ...
Cuadrado Cabello, Agustín (Date of defense: 2019-03-07)
Coupled processes between the soil and the atmosphere control soil water evaporation in its first stage, which leads to soil shrinkage and cracking by drying. However, soil-atmosphere interaction has received little attention ...
Russian, Anna (Date of defense: 2013-03-01)
This thesis studies diffusion phenomena in heterogeneous media, which includes Darcy flow and diffusive solute transport in geological media. Natural media are heterogeneous at different scales, which induces complexity ...
Ferrer Ramos, Núria (Date of defense: 2019-07-18)
One of the main drivers of the current global change is the climate change characterized by increased number and increased length of drought periods. Another relevant driver that will imply greater pressure on natural ...
Domènech i Surinyach, Guillem (Date of defense: 2015-10-14)
Due to the exponential grown of the population within the last decades, the landslide hazard assessment of earthflows and rockfalls and their hazard mapping have become an essential tool for the territory management, mostly ...
Herrera Lameli, Christian (Date of defense: 2001-07-06)
La Isla de Fuerteventura se sitúa en el borde oriental del Archipiélago de Canarias, a sólo 100 km del continente africano. Presenta un relieve topográfico relativamente suave respecto a las otras islas del Archipiélago, ...
Alvarado de Menéndez, Clara Elena (Date of defense: 2017-05-18)
Rockfill is a coarse material widely used in geotechnical works such as earth-fill dams (shoulders and toe drains), as well as in embankments and well-graded quarry materials for railway infrastructures. These structures ...
Butlanska, Joanna (Date of defense: 2014-07-21)
Cone penetration test (CPT) is a fast and reliable site investigation tool for exploring soils and soft ground. While the interpretation of the test results in clay has advanced considerably from a theoretical and numerical ...
Gran Esforzado, Meritxell (Date of defense: 2015-05-27)
Unsaturated flow plays an important role in numerous environmental phenomena. It is complex in arid regions, where liquid water fluxes are small and vapor fluxes become relevant, so that heat, water and solute mass transport ...
Núñez Andrés, M. Amparo (María Amparo) (Date of defense: 2006-11-10)
The following dissertation partially gathers the research carried out within two projects of the DGICyT (Dirección General de Investigación Científica y Técnica, Spanish Government Department for Scientific and Technical ...
Raïmat Quintana, Carles (Date of defense: 2018-07-23)
Debris flows are one of the most dangerous mass movements in mountainous regions, but with many outstanding issues on hydrological conditions, mechanisms triggering, dynamic flow and mitigation measures. This work in the ...
García Ríos, María (Date of defense: 2015-03-13)
A test site for CO2 geological storage is situated in Hontomín (Burgos, northern Spain) with a reservoir rock that is mainly composed of limestone (80-85%) and sandstone (15-20%). The reservoir rock is a deep saline aquifer ...
Villarraga Díaz, Claudia Juliana (Date of defense: 2018-02-28)
The environmental conditions may play a relevant role in the stability of rock slopes. In fact, weathering can contribute to the reduction of strength of the material, while atmospheric actions may increase internal stresses ...
