(English) When concrete is subject to an environment characterised by a high humidity index and rich in sulphate ions, a concrete degradation process may be initiated due to External Sulphate Attack (ESA). The sulphate ...
La modelació del transport reactiu multifàsic (TRMF) involucra la simulació del flux de fases fluïdes, el transport de compostos químics i energia, i les reaccions químiques. La majoria dels codis de transport reactiu ...
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 ...
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 ...
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 ...
(English) Driven piles in granular soils gain shaft capacity after installation in a phenomenon known as “pile set-up”. Set-up effects in sand have not been incorporated into design procedures largely because the underlying ...
This thesis explores the potential of models based on the discrete element method (DEM) to study dynamic probing of granular materials, considering realistic particle-scale properties. The virtual calibration chamber ...
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 ...
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, ...
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 ...
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 ...
La tesis se compone de dos partes: en primer lugar se combina de manera totalmente acoplada una nueva formulación para el problema de transporte reactivo con una formulación termo-hidro-mecánica (THM) ya existente. A ...
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 ...
Materiales arcillosos rígidos, que se encuentran en la zona de transición entre suelos duros y rocas blandas, están siendo considerados actualmente en varios países como la roca huésped para el almacenamiento geológico ...
El treball presentat en aquesta memòria aplica la tecnologia dels Sistemes de Información Geogràfica (SIG) a l'evaluació de la susceptibilitat del terreny a lliscaments i a la seva representació cartogràfica. Amb aquesta ...
Concrete is one of the most used materials in construction, and its application spans to all kinds of structures. For this reason, concrete has been the subject of intense study. In spite of that, there are still apects ...
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 ...
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 ...
(English) The term rockfall applies to blocks or masses of rock that, after separating from a steep wall, experience free fall and then impact against the ground, with the consequent rebound and possible rolling and sliding ...
En las últimas décadas la literatura se ha centrado en la estimación de la recarga natural y los parámetros que la controlan, incluyendo clima, vegetación, suelo, y topografía. Por el contrario, pocos son los trabajos ...
