Drinking Water Provision and Quality at the Sahrawi Refugee Camps in Tindouf (Algeria) From 2006 to 2016
(Elsevier, 2021)[Abstract] Drinking water provision has been a constant challenge in the Sahrawi refugee camps, located in the desert near Tindouf (Algeria). The drinking water supply system is itself divided in three zones which pump ... -
Dynamic calculation of breakwater crown walls under wave action: influence of soil mechanics and shape of the loading state
(MDPI, 2019)[Abstract:] As a consequence of the action of waves on rubble mound breakwaters, there are loads—both on the vertical and horizontal sides of the crown walls—which modify the conditions of their stability. These loads ... -
Dynamical Study of a Moored Vessel Using Computer Vision
(Springer, 2018)[Abstract]: Wind and wave effects have a major impact on the design of mooring and anchoring systems, whose purpose is to prevent the movement of the cargo and the moored ship while optimizing the operations which have to ... -
Editorial: flood susceptibility and risk maps as a crucial tool to face the hydrological extremes in developing countries: technical and governance aspects linked by a participatory approach
(Frontiers Media, 2022)[Abstract:] In summary, this Research Topic wants to draw attention to two points of reflection: 1) The need to involve stakeholders at all levels in the planning of actions aimed at reducing the risks associated with ... -
Editorial—Physical Modelling in Hydraulics Engineering
(MDPI, 2021)[Abstract] Note: In lieu of an abstract, this is an excerpt from the first page: Laboratory experiments and field works play a crucial role in hydraulic research, development, and design as many hydraulic processes elude ... -
Effect of rainfall uncertainty on the performance of physically based rainfall–runoff models
(Wiley, 2019)[Abstract:] This paper analyses the effect of rain data uncertainty on the performance of two hydrological models with different spatial structures: a semidistributed and a fully distributed model. The study is performed ... -
Estimation of flood-exposed population in data-scarce regions combining satellite imagery and high resolution hydrological-hydraulic modelling: A case study in the Licungo basin (Mozambique)
(Elsevier, 2022)[Abstract:] Study Region Licungo basin (Mozambique) Study Focus The Licungo basin (23,263 km2) suffers frequent severe flooding due to tropical storms, in a country that is among the world’s most vulnerable in terms of ... -
European stakeholders’ visions and needs for stormwater in future urban drainage systems
(Taylor & Francis, 2023)[Abstract:] Transitioning urban drainage systems to serve water-smart societies requires the involvement of different disciplines and stakeholders. However, stakeholders have different visions and needs from the transitioning ... -
Evaluation of 2D Hydrodynamic-Based Rainfall/Runoff Modelling for Soil Erosion Assessment at a Seasonal Scale
(Elsevier, 2024)[Abstract:] Badlands are often the source of a significant fraction of the sediment reaching the river network due to the exposure of the bare soil to the impact of rain drops and to the bed shear stress generated by the ... -
Experimental and Numerical Analysis of Egg-Shaped Sewer Pipes Flow Performance
(Multidisciplinary Digital Publishing Institute, 2016)A Computational Fluid Dynamics (CFD) model was developed to analyze the open-channel flow in a new set of egg-shaped pipes for small combined sewer systems. The egg-shaped cross-section was selected after studying several ... -
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 ... -
