3D physical modeling for checking Level III probabilistic design in breakwaters: A case study in Punta Langosteira Port, Spain
(Taylor & Francis, 2019)[Abstract:] The structural design of a breakwater is usually carried out by applying the verification equations existing in the literature in order to analyze the different failure modes. It is also common to perform ... -
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 continuous simulation approach for the estimation of extreme flood inundation in coastal river reaches affected by meso- and macrotides
(Springer, 2018)[Abstract:] Considering the joint probability of occurrence of high sea levels and river discharges, as well as the interactions between these sources of flooding, is of major importance to produce realistic inundation ... -
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 European Multi Lake Survey dataset of environmental variables, phytoplankton pigments and cyanotoxins
(Springer Nature, 2018)[Abstract:] Under ongoing climate change and increasing anthropogenic activity, which continuously challenge ecosystem resilience, an in-depth understanding of ecological processes is urgently needed. Lakes, as providers ... -
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 ... -
A rapid flood inundation model for hazard mapping based on least squares support vector machine regression
(Wiley, 2019)[Abstract:] Two-dimensional shallow water models are widely used tools for flood inundation mapping. However, even if High Performance Computing techniques have greatly decreased the computational time needed to run a 2D ... -
A Risk-Based Approach for the Analysis of Flood Impact in Villahermosa (Tabasco, Mexico)
(MDPI, 2023)[Abstract:] Floods in Villahermosa are events that have occurred frequently over the centuries, due to the city’s location at the mouth of two of the most powerful rivers in Mexico. Flooding effects on residents have become ... -
A robust method to update local river inundation maps using global climate model output and weather typing based statistical downscaling
(Springer, 2020)[Abstract:] Global warming is changing the magnitude and frequency of extreme precipitation events. This requires updating local rainfall intensity-duration-frequency (IDF) curves and flood hazard maps according to the ... -
A simple pseudo-Compact tension (pCT) test apparatus to determine the mode I fracture toughness
(Elsevier, 2024)[Abstract:] We introduce a simplified pseudo-compact tension (pCT) test apparatus, specifically designed to accurately determine the mode I fracture toughness (KIC) under direct tension conditions for rocks and other ... -
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 the reduction processes at the bottom of Lake Meirama: a singular case of lake formation
(Springer, 2023)[Abstract:] The formation of natural lakes is a process that takes place over thousands of years, although the volumetric formation depends on hydrological and climatological phenomena, reaching a stationary hydraulic ... -
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 ... -
