3-Dimensional numerical study on the critical orientation of the flooded passenger vehicles
(International Association of Engineers (IAENG), 2023-09)
Article
Accés restringit per política de l'editorialVehicles are one of the most common objects that are usually washed away by the water flow during flood events resulting in several damages and casualties. Regardless of the vehicle type and flow condition, vehicle ... -
3D downscaling model for radar-based precipitation fields
(2006-10)
Article
Accés obert -
A comparison of Eulerian and Lagrangian transport and non-linear reaction algorithms
(Elsevier, 2017-01)
Article
Accés obertWhen laboratory-measured chemical reaction rates are used in simulations at the field-scale, the models typically overpredict the apparent reaction rates. The discrepancy is primarily due to poorer mixing of chemically ... -
A CUDA Fortran GPU-parallelised hydrodynamic tool for high-resolution and long-term eco-hydraulic modelling
(Elsevier, 2023-03)
Article
Accés obertEco-hydraulic models are wide extended tools to assess physical habitat suitability on aquatic environments. Currently, the application of these tools is limited to short river stretches and steady flow simulations. However, ... -
A fuzzy logic technique for identifying nonprecipitating echoes in radar scans
(American Meteorological Society, 2006-09)
Article
Accés obertBecause echoes caused by nonmeteorological targets significantly affect radar scans, contaminated bins must be identified and eliminated before precipitation can be quantitatively estimated from radar measurements. Under ... -
A large bridge pier in an alluvial channel: local scour versus morphological effects and the role of physical models
(American Society of Civil Engineers, 2022-08)
Article
Accés restringit per política de l'editorialThe large pier of an emblematic bridge built in 2008 in the Ebro River (Zaragoza, Spain) obstructs the flow in high floods. Clear-water scour experiments in a scale model were conducted to anticipate maximum local scour ... -
A methodology for attenuation correction based on the minimization of a cost function
(American Meteorological Society, 2003)
Text en actes de congrés
Accés obert -
A model based on Hirano-Exner equations for two-dimensional transient flows over heterogeneous erodible beds
(Elsevier, 2016-01)
Article
Accés obertIn order to study the morphological evolution of river beds composed of heterogeneous material, the interaction among the different grain sizes must be taken into account. In this paper, these equations are combined with ... -
A new experiments-based methodology to define the stability threshold for any vehicle exposed to flooding
(Taylor & Francis, 2017-09)
Article
Accés obertA vehicle exposed to flooding, after losing stability, becomes buoyant and may be washed away with potential injuries and fatalities. Such vehicles cause additional disruption to traffic that is already affected by flooding, ... -
A novel expert opinion-based approach to compute estimations of flood damage to property in dense urban environments. Barcelona case study
(Elsevier, 2021-07)
Article
Accés obertA certain acceptable level of risk in a major drainage system must be established since urban areas cannot be made entirely free from pluvial flooding. Among the diversity of flood risks in urban areas, direct damage to ... -
A physical-chemical study of water resources in 5 hydropower projects
(Brazilian Journals Publicações de Periódicos e Editora Ltda, 2022-11-14)
Article
Accés obertOver the last 60 years, renewable energies have substantially developed; in 2021, around 12.8% of global primary energy came from these technologies. Thus, even though renewable energies have good global acceptance present ... -
A radar-based flash flood forecasting for the Llobregat river basin in the Catalonia region (Spain)
(American Meteorological Society, 2011)
Comunicació de congrés
Accés obertIn this research paper, a flash flood modeling system implemented in a Mediterranean river basin is presented. Radar precipitation estimation along with hydrological modeling techniques are implemented within the system ... -
A random walk solution for modeling solute transport with network reactions and multi-rate mass transfer in heterogeneous systems: Impact of biofilms
(Elsevier, 2015-12)
Article
Accés obertThe interplay between the spatial variability of the aquifer hydraulic properties, mass transfer due to sub-grid heterogeneity and chemical reactions often complicates reactive transport simulations. It is well documented ... -
A review of flood impact assessment approaches for underground infrastructures in urban areas: a focus on transport systems
(2020-06)
Article
Accés obertFlooding events can produce significant disturbances in underground transport systems within urban areas and lead to economic and socioenvironmental well-known consequences, which can be worsened by variations in the ... -
A review of safety guidelines for vehicles in floodwaters
(2021-04)
Article
Accés obertThe development of guidelines for the design and analysis of street drainage systems to ensure safety of pedestrians and vehicles is an issue of fundamental importance. To prevent pedestrians and vehicles from being swept ... -
A sand-gravel Gilbert delta subject to base level change
(American Geophysical Union (AGU), 2018-05)
Article
Accés obertLaboratory experiments were conducted on a sand-gravel Gilbert delta to gain insight on its dynamics under varying base level. Base level rise results in intensified aggradation over the topset, as well as a decrease in ... -
