GIS-based hydrogeologica platform for sedimentary media 

Velasco Mansilla, Domitila Violeta (Date of defense: 2013-12-17)

The detailed 3D hydrogeological modelling of sedimentary media that form important aquifers is very complex because of: (1) the natural intrinsic heterogeneity of the geological media, (2) the need for integrating reliable ...

A methodology to assess the combined effect of climate change and groundwater overexploitation over the Upper Guadiana basin, Spain 

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 ...

Sediment-water interaction in a water reservoir affected by acid mine drainage : experimental and modeling 

Torres Sánchez, Ester (Date of defense: 2013-11-15)

The discharge of acid mine drainage into a water reservoir may seriously affect the water quality. In this setting, sediment is commonly thought to act as a sink for pollutants. However, redox oscillations in the bottom ...

Monitoring and geomorphologic characterization of debris flows at catchment scale : contributions to debris-flow hazard assessment 

Abancó Martínez de Arenzana, Clàudia (Date of defense: 2013-06-27)

Debris flows are very fast mass movements and are considered as one of the most hazardous phenomenain mountainous regions. Research on this field has strongly improved during the last decades. However,many open questions ...

Interaction between groundwater and underground constructions 

Pujades Garnes, Estanislao (Date of defense: 2013-11-27)

Underground constructions below the water table may be problematic if the role of groundwater is not properly acknowledged. Difficulties worsen in urban environments. Two aspects should be taken into account in the interaction ...

Análisis estructural estático y dinámico probabilista de edificios de hormigón armado. Aspectos metodológicos y aplicaciones a la evaluación del daño. 

Vargas Alzate, Yeudy Felipe (Date of defense: 2013-07-09)

Esta tesis propone una metodología de evaluación del daño sísmico basada en el método del espectro de capacidad pero con un enfoque probabilista que se apoya en simulaciones Monte Carlo. Así la acción sísmica, la estructura ...

Tools and analysis of spatio-temporal dynamics in heterogeneous aquifers: applications to artificial recharge and forced-gradient solute transport 

Pedretti, Daniele (Date of defense: 2012-12-21)

This thesis deals with the development of tools and analysis to characterize and predict artificial recharge and radial convergent solute transport processes in heterogeneous media. The goal is to provide new insights to ...

Effect of redox conditions on the fate of emergin organic micropollutants during artificial recharge of groundwater: batch experiment 

Barbieri, Manuela (Date of defense: 2011-07-22)

La recarrega artificial de les aigües subterrànies consisteix en infiltrar aigua als aqüífers per mitjà de les instal·lacions dissenyades per a tal fi i representa una eina important en la gestió dels recursos. A més de ...

Riego y fertilización nitrogenada en maíz (zea mays l.): efecto sobre el rendimiento del cultivo y la contaminación subterránea por nitratos 

Poch Massegú, Ricard (Date of defense: 2012-03-30)

Intensive farming often leads environmental consequences. This is the case of the study area of this thesis: the Empordà, a region with a variety of intensive crops (fruits, cereals, forage,...) and manifest problems of ...

Interaction between groundwater and TBM (Tunnel Boring Machine) excavated tunnels 

Font Capó, Jordi (Date of defense: 2012-09-26)

A number of problems, e.g. sudden inflows are encountered during tunneling under the piezometric level, especially when the excavation crosses high transmissivity areas. These inflows may drag materials when the tunnel ...

Proposal of energy spectra for earthquake resistant design based on turkish registers 

Yazgan, Ahmet Utku (Date of defense: 2012-09-07)

This work proposes design energy spectra in terms of an equivalent velocity, intended for regions with design peak acceleration 0.3 g or higher. These spectra have been derived through linear and nonlinear dynamic analyses ...

Un Nuevo enfoque de los precursores sísmicos: monitorización de la interacción frágil-dúctil de la litosfera y su relación con grandes terremotos 

Tarela Alonso, Ester (Date of defense: 2012-06-22)

The main goal of this thesis is to test the brittle-ductile (BD) interaction hypothesis of the lithosphere. The model uses the correlation of two parameters, the seismicity characterizing the brittle part and the attenuation ...

Comportamiento deformacional del suelo no saturado bajo condiciones drenadas y no drenadas 

Lloret Morancho, Antonio (Date of defense: 1982-07-12)

Se ha elaborado un modelo general para la consolidación del suelo parcialmente saturado en condiciones unidimensionales. El modelo acopla los cambios de succión con la deformación volumétrica a través del concepto de ...
