Pervious concrete is a special material with high permeability usually obtained by reducing the amount of fine aggregates in the composition of concrete. The properties of pervious concrete not only depend on its composition ...
The main objective of this thesis is to characterize hydrological processes in a Mediterranean mountain catchment, by combining distributed hydrological measurements and environmental tracers in order to improve the ...
Seawater intrusion (SWI) causes not only salinization of coastal aquifers, but also a reduction submarine groundwater discharge (SGD) and nutrient fluxes to marine ecosystems. We have developed a small scale experimental ...
The concrete-steel composite slabs show a complex structural characterization due to the different behaviours at the two materials. The materials are exposed to different deformations, large deflections and complex stresses ...
(English) Light attenuation is a critical factor in aquatic ecosystems for many physical and biological processes. Water transparency plays an essential role in understanding the variations of the ecological environment ...
(English) The exponential growth of world population is leading to a high demand of food products and, consequently, to the development of intensive agricultural and livestock systems. In this sense, synthetic fertilizers ...
Coastal zones concentrate an elevated number of values both natural and socio-economic, making them very vulnerable to the potential effects of natural hazards. Therefore, effective risk management requires a holistic ...
This thesis proposes a coupled continuous and hybridizable discontinuous Galerkin formulation to solve conjugate heat transfer problems. This model is then used to find the thermal response of Glass Fiber Reinforced Polymer ...
This thesis discusses which transit network structure is the best option to serve urban mobility. As a consequence of the evolution of urban form, cities have undergone a dispersion process of their activities. This fact ...
Anaerobic digestion (AD) is currently spread all over the world for sewage sludge stabilisation, volume reduction and green energy production. Its implementation contributes to turn a wastewater treatment plant (WWTP) into ...
The present thesis explores the viability of the proper generalised decomposition (PGD) as a tool for parametric studies in a daily industrial environment. Starting from the equations modelling incompressible flows, the ...
This thesis analyzes the hydro-mechanical behavior under a generalized stress state of a compacted mixture of sand (30%) and clayey (70%) at a low density. The experimental study focuses on the analysis of shear strength ...
Rockfill is a coarse material widely used in geotechnical works such as earth-fill dams (shoulders and toe drains), as well as in embankments and well-graded quarry materials for railway infrastructures. These structures ...
The objectives of this thesis are (i) to understand the thermal, metallurgical and mechanical behavior during AM, (ii) to shed light on the generation of residual stresses and the stress-induced deformations and cracks, ...
Masonry is an ancient building material that has been used throughout the history, and it is still used nowadays. Masonry constitutes the main building technique adopted in historical constructions, and a deep understanding ...
This thesis focuses on the numerical modeling of fracture and its propagation in heterogeneous materials by means of hierarchical multiscale models based on the FE2 method, addressing at the same time, the problem of the ...
Uncertainty quantification is important in assessing and predicting the performance of complex engineering systems and processes, especially in the absence of adequate experimental or real-world data. With the increase ...
[English] In n-dimensional adaptive applications, conformal simplicial meshes must be lo cally modified. One systematic local modification is to bisect the prescribed simplices while surrounding simplices are bisected ...
The use of the fibre reinforced concrete (FRC) as a construction material has expanded beyond the traditional applications since the publication of design codes and structural guidelines. Fibre reinforced concrete for ...
Horizontal Subsurface Flow Constructed Wetlands (HSSF CWs) are natural wastewater treatment systems showing a marked redox gradient between the surface of the system and the bottom zone of the treatment bed. Therefore, ...
