Process understanding of induced seismicity during stimulation of enhanced geothermal systems
(English) This doctoral thesis investigates the causes that induce (micro)seismicity as a result of hydraulic stimulation in fractured low-permeability rock. Understanding such phenomenon is of paramount importance to ...
Understanding and mitigating the post-injection seismicity induced by fluid injection in enhanced geothermal systems
(English) Induced seismicity due to hydraulic stimulation and circulation is a hurdle for the development of Enhanced Geothermal Systems (EGS). The monitored seismicity has occasionally reached magnitudes large enough to ...
Sistema de evaluación y priorización de inversiones públicas
(English) This doctoral thesis addresses one of the most significant challenges facing the Spanish administration: the efficient selection and management of public investments. To achieve this goal, the 'Public Investment ...
Novel tools for port environmental management systems
(English) This thesis addresses the development and evaluation of novel tools and strategies for Environmental Management Systems (EMS) implementation in ports for water quality. Integrating computer vision-based systems ...
A methodology for the design, implementation and evaluation of community and impact-based flood warnings
(English) The present thesis focuses on developing, implementing, and evaluating a comprehensive community and impact-based early warning system (EWS) framework to support the protection actions of authorities and citizens ...
Sedimentación fina y corrientes de turbiedad en embalses. Caso de estudio: Embalse Amaluza (Ecuador)
(English) Turbidity currents in reservoirs are of strong scientific interest because they can be responsible for the contribution of large amounts of fine sediments that can cause early sediment filling. The case study ...
Design, management, and simulation of mixed station-based and free-floating vehicle-sharing systems
(English) This thesis provides tools, based on mathematical modelling, for the analysis, optimization and simulation, of vehicle-sharing systems. The thesis addresses various implementation levels of such systems, from ...
Quick assessment through analytical solutions of induced seismicity in geo-energy applications
(English) Understanding the triggering mechanisms of induced seismicity remains one of the most critical challenges in geo-energy applications. This Thesis aims at assessing (1) fault stability and induced seismicity ...
Topology optimization of incompressible structures for fluid-structure interaction problems
(English) Topology optimization of incompressible structures, in which the loads on the structure come from the stresses exerted by a surrounding fluid, is a highly complex problem. This work presents a compilation of the ...
Assessment of groundwater hydrology of the Quaternary aquifer of Lake Chad Basin
(English) This thesis aims to enhance the conceptual model of the Lake Chad Basin's quaternary aquifer by gathering updated hydrological, geological, meteorological, and groundwater data. Objectives include analyzing natural ...
Experimental velocity profile distribution characterization of mountain rivers
(English) The aim of this thesis is to improve our understanding of the behaviour of mountain rivers and to predict their morphological functioning under conditions of low relative submergence. Mountain rivers have received ...
Metodología para estimación del daño sísmico en edificios en base a modelos numéricos avanzados y monitorizaciones RAR
(English) In post-seismic scenarios, the rapid and safe evaluation of structural damage is essential to develop an effective response during the recovery, rehabilitation and reconstruction stages. The development of new ...
New updated reference Lagrangian smooth particle hydrodynamics framework for large strain solid dynamics ans its extension to dynamic fracture
(English) This work presents a new updated reference Lagrangian Smooth Particle Hydrodynamics (SPH) algorithm for the analysis of large deformation by introducing a novel system of first order conservation laws. Both ...
Coupling shallow water models with three-dimensional models for the study of fluid-structure interaction problems using the particle finite element method
(English) This thesis investigates numerical methods for the simulation of surface water flows, focusing on the interaction between the large scale and the local scale and its application to natural hazards. Several families ...
Incisión de ríos por extracción aluvial y retirada de presas. Estudio matemático y experimental.
This Thesis deals with incision (bed degradation or general bed scouring) in rivers. More specifically it deals with the incision caused by gravel mining and by dam removal. The main goal of the research is to know ...
Finite element simulation of additive manufacturing with enhanced accuracy
This thesis develops numerical methods to improve the accuracy and computational efficiency of the part-scale simulation of Additive Manufacturing (AM) (or 3D printing) metal processes. AM is characterized by multiple ...
Model order reduction methods for sensor data assimilation to support the monitoring of embankment dams
The latest monitoring and asset management technologies for large infrastructures involve digital representations that integrate information and physical models, exist in parallel to the real-life structures, and are ...
Anàlisi de susceptibilitat torrencial en conques d’alta muntanya a partir de la proposta de paràmetres indicadors : construcció d'una base de dades multidisciplinària per al desenvolupament d'una zonificació de perillositat torrencial : cas específic d’Andorra
Over the last 40 years, in Europe in general and in many mountainous regions in particular, there have been major instances of severe flood episodes (more than 100) which have resulted in more than 700 deaths and billions ...
Evaluación de proyectos de infraestructuras de transporte en dos etapas con impactos de no directa monetización
The constant and rapid population growth goes hand in hand with an increased demand for services that governments have the duty to satisfy with the problem of limited financial resources. Transport infrastructure is one ...
Identification of material properties and phase distribution of heterogeneous materials through data-driven computational methods : towards an enhanced constitutive space
Identifying the constitutive relations of materials is an essential task to understand their behavior. Classical methods like testing can be effective in understanding these relationships, but introducing models can lead ...
