El reciclado de los pavimentos asfálticos deteriorados no es una idea nueva, no obstante, con el aumento de las exigencias medioambientales y económicas se ha convertido en una alternativa cada vez más utilizada por ...
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 ...
The results presented in this doctoral thesis aims to evaluate the possible Climate Change effects on the water resources yield by the Fluvià river basin and the Tordera river basin, both located in the autonomous region ...
In recent years the increase in waste generated by various sectors has caused problems of waste management that mostly have as final destination the landfills; however, this option it is unacceptable for the economic and ...
Las transformaciones que se han venido produciendo en el sistema productivo, a lo largo de los últimos cincuenta años en España, con la pérdida de peso de la actividad propiamente manufacturera en beneficio de los servicios, ...
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 ...
This thesis presents an experimental approach on the subject of cracking in soils due to changes in environmental conditions, where research is mainly directed to the soil-air interface and the effect of boundary conditions. ...
The thesis focuses on the experimental and theoretical aspects of the process of cracking in drying soils. The results and conclusions were drawn from an exhaustive experimental campaign characterised by innovative ...
Fluvial bifurcations are systems that have a great influence on human society. Their formation and evolution can affect to activities as agriculture or industry and a good knowledge of the mechanisms that affect the processes ...
Torrential flows have so far been studied less than have river flows, due to the difficulty of faithfully reproducing them in the laboratory, and the few field measurements available. For this reason, this present research ...
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. ...
(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 ...
Research on fine sediment transport (silt and clay) is less advanced than research on sand and gravel movement. Nevertheless, fine sediment can be the predominant fraction of the suspended load in some rivers, and its ...
La tesis se enmarca en la caracterización, a nivel material, de la fractura del hormigón reforzado con fibras de acero (SFRC) bajo solicitaciones de tracción y cortante, y sobre la determinación de parámetros que representan ...
Ocean turbulence is a classic example of turbulent motion and observations of turbulence in the ocean lack in regions of complex topography since in-situ and experimental data are complicated to obtain. As a result, ocean ...
The objective of the thesis is to develop a numerical tool to describe how the concentration of one or more substances distributed in a fluid environment changes under the effect of three transport processes: advection, ...
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 ...
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 ...
(English) Cycles in the construction sector and economy disguise what appears to advance in occupational risk prevention when, unfortunately, the AECO sector maintains very high accident rates. The zero accident target is ...
