Occurrence of debris flows has received little attention in the Pyrenees, probably due to the small risk faced by most of the debris-flow prone sites in this mountain range. Nevertheless, the event of Biescas, which occurred ...
El crecimiento continuo de las ciudades, o la ocurrencia de un evento extraordinario de lluvia, en muchas ocasiones sobrepasa las medidas de diseño de algunos de los elementos del drenaje urbano (principalmente elementos ...
The finite element method is a valuable tool for simulating complex physical phenomena. However, any finite element based simulation has an intrinsic amount of error with respect to the exact solution of the selected ...
This thesis deals with uncertainty in radar-based precipitation estimation and nowcasting in two ways: its quantification in a probabilistic manner, and its reduction in the precipitation estimates. A straightforward way ...
Tradicionalmente la construcción de aliviaderos escalonados en presas de hormigón compactado con rodillo (HCR) se caracteriza por la presencia de muretes guías que imponen un ancho constante a lo largo del aliviadero y que ...
Magnetohydrodynamics (MHD) is the physics branch that studies electrically conducting fluids under external magnetic fields. This thesis deals with the numerical approximation using stabilized finite element methods of two ...
L’objectiu de la Monitorització de la salut estructural (SHM) és la verificació de l’estat o la salut de les estructures per tal de garantir el seu correcte funcionament i estalviar en el cost de manteniment. El sistema SHM ...
Climate change is a hot research topic due to the consequent impacts on our environment in the near future. The last report of the International Panel on Climate Change' the leading international body for assessment of ...
The Doñana wetlands, in Southwest Spain, undergo yearly cycles of inundation in fall and drying out during the spring season. As any wetland ecosystem, Doñana depends critically on its water resources. Important monitoring ...
The process of containerization and its continuous development involves changes and technological innovations in containerships and maritime container terminals. In the current era of "gigantism", despite existing fleet ...
This paper presents a numerical approach for the simulation of reinforced concrete pieces in three dimensions, using embedded discontinuity elements, based on the strong discontinuity approach. In turn, this work is divided ...
Las biomembranas constituyen la estructura de separación fundamental en las celulas animales, y son importantes en el diseño de sistemas bioinspirados. Su simulación presenta desafíos, especialmente cuando ésta implica ...
The accumulation of sediments in combined sewer systems may give rise to significant quality problems, which sometimes are overlooked. Solids deposited in the network may lead to more frequent overflows into natural waters, ...
El flujo desbordado en secciones de ríos con llanuras de inundación (secciones compuestas) presenta fuertes fenómenos tridimensionales que lo diferencian del flujo confinado en el cauce principal (asimilable a secciones ...
The use of concrete in disposal facilities to store low- and intermediate-level nuclear waste requires that the durability of this material is optimal for the lifetime of these repositories. One of the most important ...
This thesis aims to develop a predictive control for irrigation canals to improve the management of water resources. Water is necessary for life and it is a scarce good that we need for drinking, in the agriculture, etc. ...
Huge modifications have been made to landscape or urban watersheds, especially in twentieth century, caused by increases in urbanization have led to progressive increases in runoff flows and therefore sediment production. ...
The development and population prosperity in the transition zone between the Sahara desert in the north and the tropical humid savannah in the south, known as Sahel, depends to a great extent on the rainfall regime. The ...
Geochemical and reactive transport modelling are essential tools in hydrogeology. They help to identify and assess geochemical processes occurring in applications such as groundwater contamination, water-rock interactions ...
The present work is a compilation of the research produced in the field of wave propagation modeling. It contains in-depth analysis of stability, convergence, dispersion and dissipation of spatial, temporal and spatial-temporal ...
