Extension of the two‐component pressure approach for modeling mixed free‐surface‐pressurized flows with the two‐dimensional shallow water equations
(Wiley, 2021)[Abstract:] Numerical models based on the two-dimensional shallow water equations (2D-SWE) are routinely used in flood risk management and inundation studies. However, most of these models do not adequately account for ... -
Field campaign on pressure on the crown wall at the outer port of Punta Langosteira breakwater
(MDPI, 2022)[Abstract:] Punta Langosteira port, located in A Coruña (Spain), was monitored during the winters of 2017 and 2018, measuring wave pressure in the crown wall structure. Furthermore, the metocean variables were measured on ... -
Field measurements of angular motions of a vessel at berth: Inertial device application
(Romanian Soc Control Tech Informatics, 2018)[Abstract]: The study and characterization of the oscillations of a moored vessel has a major importance in port operational efficiency, not only in the design of mooring and anchoring systems, but also in order to prevent ... -
Flood risk in urban areas: modelling, management and adaptation to climate change. A review
(MDPI, 2022)[Abstract:] The modelling and management of flood risk in urban areas are increasingly recognized as global challenges. The complexity of these issues is a consequence of the existence of several distinct sources of risk, ... -
Global and local sensitivity analysis to improve the understanding of physically-based urban wash-off models from high-resolution laboratory experiments
(Elsevier, 2019)[Abstract:] Physically-based urban wash-off models are a promising means of studying the transport of finer suspended solids and their associated pollutants during rain events, considering spatial and temporal heterogeneities. ... -
How Do Modeling Choices and Erosion Zone Locations Impact the Representation of Connectivity and the Dynamics of Suspended Sediments in a Multi-Source Soil Erosion Model?
(Copernicus GmbH, 2021)[Abstract] Soil erosion and suspended sediment transport understanding is an important issue in terms of soil and water resources management in the critical zone. In mesoscale watersheds (>10 km2) the spatial distribution ... -
Hydraulic modeling of bridges in two-dimensional shallow water models
(American Society of Civil Engineers, 2022)[Abstract:] The backwater effect generated by bridges can significantly increase the risk of flooding. In this work we compare two different methods to include the effect of bridges in two-dimensional (2D) shallow water ... -
Hydraulic, Wash-off and Sediment Transport Experiments in a Full-Scale Urban Drainage Physical Model
(Nature, 2020)[Abstract] This paper presents a dataset obtained from hydraulic and sediment transport experiments performed in a full-scale urban drainage physical model of 36 m2. The study seeks to accurately measure sediment mobilization ... -
Hydrostatic, strike-slip and normal stress true triaxial hydrofracturing testing of Blanco Mera Granite: breakdown pressure and tensile strength assessment
(Springer, 2023)[Abstract:] We have designed and built a versatile testing device to perform hydraulic fracturing experiments under true triaxial conditions. The device, based on a stiff biaxial frame that can be installed in a servocontrolled ... -
IberWQ: A GPU Accelerated Tool for 2D Water Quality Modeling in Rivers and Estuaries
(MDPI, 2020)[Abstract] Numerical models are useful tools to analyze water quality by computing the concentration of physical, chemical and biological parameters. The present work introduces a two-dimensional depth-averaged model that ... -
IberWQ: new simulation tool for 2D water quality modelling in rivers and shallow estuaries
