A comparison of missing value imputation methods applied to daily precipitation in a semi-arid and a humid region of Mexico
(Universidad Nacional Autónoma de México, 2023)[Abstract:] Climatological data with unreliable or missing values is an important area of research, and multiple methods are available to fill in missing data and evaluate data quality. Our study aims to compare the ... -
A decision-making tool for port operations based on downtime risk and met-ocean conditions including infragravity wave forecast
(MDPI, 2023)[Abstract:] Port downtime leads to economic losses and reductions in safety levels. This problem is generally assessed in terms of uni-variable thresholds, despite its multidimensional nature. The aim of the present study ... -
A Hybrid Neural Network-Based Technique to Improve the Flow Forecasting of Physical and Data-Driven Models: Methodology and Case Studies in Andean Watersheds
(Elsevier, 2020)[Abstract] Study region The present study was conducted in the Machángara Alto and Chulco rivers, which belong to the Paute basin in the provinces of Azuay and Cañar in southern Ecuador. Study focus Andean watersheds ... -
An accelerated tool for flood modelling based on Iber
(MDPI, 2018)[Abstract:] This paper presents Iber+, a new parallel code based on the numerical model Iber for two-dimensional (2D) flood inundation modelling. The new implementation, which is coded in C++ and takes advantage of the ... -
An Application of Fish Detection Based on Eye Search with Artificial Vision and Artificial Neural Networks
(MDPI AG, 2020-10-27)[Abstract] A fish can be detected by means of artificial vision techniques, without human intervention or handling the fish. This work presents an application for detecting moving fish in water by artificial vision based ... -
An Augmented Reality Facility to Run Hybrid Physical-Numerical Flood Models
(MDPI, 2020)[Abstract] This article presents a novel installation for the development of hybrid physical-numerical flood models in an augmented reality environment. This installation extends the concept introduced by the well-known ... -
An UAV and Satellite Multispectral Data Approach to Monitor Water Quality in Small Reservoirs
(MDPI, 2020)[Abstract] A multi-sensor and multi-scale monitoring tool for the spatially explicit and periodic monitoring of eutrophication in a small drinking water reservoir is presented. The tool was built with freely available ... -
Analysis of Particulate Matter Concentration Intercepted by Trees of a Latin-American Megacity
(MDPI, 2021)[Abstract] Urban areas with trees provide several ecosystem services to citizens. There is a growing interest in ecosystem services for the removal of air pollutants such as particulate matter. The objective of this paper ... -
Analysis of surrogate physicochemical parameters for studying heavy metal pollution in urban road runoff
(MDPI, 2023)[Abstract:] The pollution associated with road runoff water can generate significant impacts on the receiving natural environment due to the significant masses mobilized under certain climate, morphological, and anthropic ... -
Analysis of two sources of variability of basin outflow hydrographs computed with the 2D shallow water model Iber: Digital Terrain Model and unstructured mesh size
(Elsevier, 2022)[Abstract:] Modelling hydrological processes with fully distributed models based on the shallow water equations implies a high computational cost, which often limits the resolution of the computational mesh. Therefore, in ... -
Análisis integral del lavado y arrastre de sólidos en suspensión en cuencas urbanas utilizando un simulador de lluvia a escala real
(Universitat Politècnica de València, 2022)[Resumen:] Ante la falta de datos experimentales precisos para el desarrollo y validación de modelos de lavado y transporte de sedimentos en la superficie de cuencas urbanas, en este estudio se presenta una serie de ensayos ... -
Análisis y evaluación de las alternativas de protección de las aguas subterráneas durante las operaciones de extracción de los residuos (alquitranes ácidos) en una laguna de Arganda del Rey (Madrid)
(Instituto Geológico y Minero de España, 2021)[Resumen:] La Comunidad de Madrid está llevando a cabo la restauración integral de una antigua gravera contaminada con residuos peligrosos, mayoritariamente sulfonatos de petróleo (alquitranes ácidos), procedentes del ... -
Anisotropic deformability and strength of slate from NW-Spain
(Elsevier, 2021)[Abstract:] Slates are metamorphic rocks characterized by the pervasive occurrence of cleavage or foliation producing a highly anisotropic mechanical behavior characterized by fissility. Deformability and strength of these ... -
Assessing Different Imaging Velocimetry Techniques to Measure Shallow Runoff Velocities During Rain Events Using an Urban Drainage Physical Model
(Copernicus GmbH, 2021)[Abstract] Although surface velocities are key in the calibration of physically based urban drainage models, the shallow water depths developed during non-extreme precipitation and the potential risks during flood events ... -
Assessing the Effects of Climate Change on Compound Flooding in Coastal River Areas
(AGU Journals, 2021)[Abstract] Flood assessment in coastal river areas is subject to complex dependencies and interactions between flood drivers. In addition, coastal areas are especially vulnerable to climate change, and thus its effects ... -
Benchmarking of Drought and Climate Indices for Agricultural Drought Monitoring in Argentina
(Elsevier, 2021)[Abstract] Site-specific studies are required to identify suitable drought indices (DIs) for assessing and predicting drought-related impacts. This study presents a benchmark of eight DIs and 19 large-scale climate indices ... -
Comparison of machine learning techniques for reservoir outflow forecasting
(European Geosciences Union, 2022)[Abstract:] Reservoirs play a key role in many human societies due to their capability to manage water resources. In addition to their role in water supply and hydropower production, their ability to retain water and control ... -
Comparison of three different numerical implementations to model rainfall-runoff transformation on roofs
(Wiley, 2022)[Abstract:] Roofs represent a high percentage of the impervious surfaces in urban areas, and hence their implementation in urban drainage models is essential for accurate results to be achieved. Current modelling approaches ... -
Development and Calibration of a New Dripper-Based Rainfall Simulator for Large-Scale Sediment Wash-off Studies
(MDPI, 2020)[Abstract] Rainfall simulators are useful tools for controlling the main variables that govern natural rainfall. In this study, a new drop-forming rainfall simulator, which consists of pressure-compensating dripper grids ... -
Development of a global SDG progress index aimed at “leaving no one behind”
(MDPI, 2020)[Abstract:] The United Nation’s Sustainable Development Goals (SDGs) constitute a set of shared global objectives for the development over the coming years, which both developed and developing countries are working together ...
