Sapriza Azuri, Gonzalo (Data de defensa: 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 ...
Vargas Alzate, Yeudy Felipe (Data de defensa: 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 ...
Domènech i Surinyach, Guillem (Data de defensa: 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 (Data de defensa: 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, ...
Butlanska, Joanna (Data de defensa: 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 (Data de defensa: 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) (Data de defensa: 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 ...
García Ríos, María (Data de defensa: 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 ...
Espinosa Martínez, Sara (Data de defensa: 2014-09-29)
To test the applicability of atmospheric chloride deposition balance and soil water balance in the estimation of aquifer recharge , the chosen area is Vall Baixa de I'Ebre. This is a coastal area of semi-arid climate, which ...
Cardona Arboleda, Omar Dario (Data de defensa: 2001-12-19)
The present research commences with a revision of the concepts of hazard, vulnerability, and risk. This is a basic requirement for the construction of the theoretical framework herein developed. A revision of commonly used ...
Barahona-Palomo, Marco (Data de defensa: 2014-02-28)
Characterization of aquifers hydraulic parameters is a difficult task that requires field information. Most of the time the hydrogeologist relies on a group of values coming from different test to interpret the hydrogeological ...
Martínez Santafé, Maria Dolors (Data de defensa: 1998-11-06)
El objetivo de este trabajo es el estudio de la estructura elástica y anelástica del sistema litosfera-astenosfera de la cuenca del mar Mediterráneo, a partir del análisis de la propagación y la atenuación de las ondas ...
Amorim, Samuel (Data de defensa: 2012-05-14)
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 ...
Mena Hernández, Ulises (Data de defensa: 2002-07-22)
Las grandes ciudades modernas situadas en áreas de peligrosidad sísmica moderada o baja tienden a minusvalorar el peligro sísmico y a descuidar precauciones básicas de protección frente a los terremotos. Ello conlleva un ...
Jaramillo Santana, Nayive (Data de defensa: 2014-06-12)
The risk coming from natural hazards is usually assessed in physical terms by estimating the losses they may cause. Nevertheless, the risk assessment can involve such aspects as the lack of economic and social development, ...
Aguilar Meléndez, Armando (Data de defensa: 2011-07-23)
In the present work a probabilistic methodology to estimate the seismic risk of buildings in urban areas is proposed. The seismic risk obtained through this methodology is expressed in terms of annual probabilities of ...
Ramon Tarragona, Anna (Data de defensa: 2014-10-27)
Geological formations containing sulphates are commonly associated with the development of severe expansions when they are involved in tunnel excavation. The intensity of the observed expansive behaviour in these materials ...
Hürlimann, Marcel (Data de defensa: 1999-12-20)
Los grandes deslizamientos volcánicos son uno de los procesos geológicos más devastadores y pueden representar un importante peligro para la población de las zonas volcánicas. Este tipo de deslizamientos puede sobrepasar ...
Velasco Mansilla, Domitila Violeta (Data de defensa: 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 ...
Pujades Garnes, Estanislao (Data de defensa: 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 ...
