Modelling Pluvial Flooding in Urban Areas Coupling the Models Iber and SWMM
Sañudo, Esteban; Cea, Luis; Puertas, Jerónimo (MDPI, 2020)[Abstract] Dual urban drainage models allow users to simulate pluvial urban flooding by analysing the interaction between the sewer network (minor drainage system) and the overland flow (major drainage system). This work ... -
Modelling Weirs in Two-Dimensional Shallow Water Models
García-Alén, Gonzalo; García Fonte, Olalla; Cea, Luis; Pena Mosquera, Luis; Puertas, Jerónimo (MDPI, 2021)[Abstract] 2D models based on the shallow water equations are widely used in river hydraulics. However, these models can present deficiencies in those cases in which their intrinsic hypotheses are not fulfilled. One of ... -
New insights to study the accumulation and erosion processes of fine-grained organic sediments in combined sewer systems from a laboratory scale model
Regueiro-Picallo, Manuel; Suárez-López, Joaquín; Sañudo, Esteban; Puertas, Jerónimo; Anta, Jose (Elsevier, 2020)[Abstract:] The deposition and resuspension of sediments are issues of considerable concern in combined sewer systems management. Sediments can produce the loss of hydraulic capacity and odour generation in sewers, and are ... -
Nonintrusive Method to Compute Water Discharge in Pipes with a Low Depth-to-Diameter Ratio Using Ultrasonic Doppler Velocimetry
Fraga, Ignacio; Cea, Luis; Puertas, Jerónimo; Anta, Jose (ASCE, 2015)[Abstract] A nonintrusive method to calculate water depth and discharge in partially full pipes using data from a single ultrasonic Doppler velocimeter (UDV) profiler is presented. The position of the free surface is ... -
On the resolution of the viscous incompressible flow for various SUPG finite element formulations
Vellando, Pablo; Puertas, Jerónimo; Bonillo Martínez, Juan José; Fe, Jaime (The International Center of Numerical Methods in Engineering, 2000)[Abstract] A Finite Element based program has been released to solve the steady 2D Navier- Stokes equations. The mixed-variable algorithm is used as a first approach to solve the differential problem. In order to reduce ... -
Pool-Type FishDesign for a Potamodromous Cyprinid in the Iberian Peninsula: The Iberian Barbel—Synthesis and Future Directions
Silva, Ana T.; Bermúdez, María; Santos, José Maria; Rabuñal, Juan R.; Puertas, Jerónimo (M D P I AG, 2020-04-21)[Abstract] The Iberian barbel (Luciobarbus bocagei) is one of the most common cyprinids in the Iberian Peninsula, whose migratory routes are often hampered by anthropogenic barriers. Fishways might be an effective mitigation ... -
Quantifying local rainfall dynamics and uncertain boundary conditions into a nested regional-local flood modeling system
Bermúdez, María; Neal, Jeffrey; Bates, Paul; Coxon, Gemma; Freer, Jim; Cea, Luis; Puertas, Jerónimo (Wiley, 2017)[Abstract:] Inflow discharge and outflow stage estimates for hydraulic flood models are generally derived from river gauge data. Uncertainties in the measured inflow data and the neglect of rainfall-runoff contributions ... -
Resolution of the flow in clarifiers by using a stabilized finite element method
Vellando, Pablo; Puertas, Jerónimo; Colominas, Ignasi (John Wiley and Sons, 2004)[Abstract] The description of the flow that takes place in clarifiers and other wastewater treatment basins may be a powerful tool to attain an optimum design of these structures, in order to make the most of the wastewater ... -
Revealing the spatio-temporal characteristics of drought in Mozambique and their relationship with large-scale climate variability
Araneda-Cabrera, Ronnie J.; Bermúdez, María; Puertas, Jerónimo (Elsevier, 2021)[Abstract:] Study region: Mozambique. Study focus: Mozambique does not currently have the necessary tools for systematic monitoring and forecasting of drought at a subnational scale. The purpose of this study was to ... -
SUPG stabilized finite element resolution of the Navier-Stokes equations: application to water treatment engineering
Vellando, Pablo; Puertas, Jerónimo; Colominas, Ignasi (Elsevier, 2002)[Abstract] In this paper an analysis of the viscous incompressible flow has been carried out, from the very definition of the governing equations, up to the resolution of some practical problems, passing through the ... -
Two-Dimensional Dam-Break Flood Analysis in Data-Scarce Regions: The Case Study of Chipembe Dam, Mozambique
Álvarez, Manuel; Puertas, Jerónimo; Peña González, Enrique; Bermúdez, María (MDPI AG, 2017)[Abstract:] This paper presents the results of a modeling study of the hypothetical dam break of Chipembe dam in Mozambique. The modeling approach is based on the software Iber, a freely available dam break and two-dimensional ... -
Urban pluvial flood modelling in the absence of sewer drainage network data: a physics-based approach
Montalvo Montenegro, Carlos Israel; Reyes-Silva, Julián David; Sañudo, Esteban; Cea, Luis; Puertas, Jerónimo (Elsevier, 2024)[Abstract:] 1D/2D dual drainage models have become one of the most useful tools in the study of urban pluvial floods. However, such models require information about the sewer network that is not always readily available. ... -
Using a 2D shallow water model to assess Large-Scale Particle Image Velocimetry (LSPIV) and Structure from Motion (SfM) techniques in a street-scale urban drainage physical model
Naves, Juan; Anta, Jose; Puertas, Jerónimo; Regueiro-Picallo, Manuel; Suárez-López, Joaquín (Elsevier, 2019)[Abstract:] Physically-based numerical modelling of surface processes in urban drainage, such as pollutant wash-off or the assessment of flood risks, requires appropriate calibration and terrain elevation data to properly ... -
Using integrated hydrological–hydraulic modelling and global data sources to analyse the February 2023 floods in the Umbeluzi Catchment (Mozambique)
Cea, Luis; Álvarez, Manuel; Puertas, Jerónimo (Copernicus Publications, 2024)[Abstract:] On 9–13 February 2023 an intense flood event took place in the province of Maputo (Mozambique), resulting in severe damage to agricultural lands and transport infrastructure and with serious consequences for ...
