Nonintrusive Method to Compute Water Discharge in Pipes with a Low Depth-to-Diameter Ratio Using Ultrasonic Doppler Velocimetry
(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 ... -
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 ... -
Two-Dimensional Dam-Break Flood Analysis in Data-Scarce Regions: The Case Study of Chipembe Dam, Mozambique
(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 ... -
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 ... -
Impact of Urban Growth and Changes in Land Use on River Flood Hazard in Villahermosa, Tabasco (Mexico)
(MDPI, 2019)[Abstract:] The city of Villahermosa, a logistical center in the State of Tabasco’s economy, is affected by recurrent river floods. In this study, we analyzed the impact of two factors that are the most probable causes of ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -

(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 ... -
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 ... -
Modelling Pluvial Flooding in Urban Areas Coupling the Models Iber and SWMM
(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 ... -
Vertically Averaged and Moment Equations for Dam-Break Wave Modeling: Shallow Water Hypotheses
(MDPI, 2020)[Abstract] The dam-break wave modeling technology relies upon the so-called shallow water equations (SWE), i.e., mass and momentum vertically averaged equations by implementing the shallow water hypotheses, namely (i) ... -
Rainwater Harvesting Techniques to Face Water Scarcity in African Drylands: Hydrological Efficiency Assessment
(MDPI, 2020)[Abstract] The sub-Saharan climate is experiencing a marked increase in temperature and intensification of precipitation intensity and variability. Besides, longer dry spells are compromising the reliability of local ... -
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 ... -
Sustainable Urban Drainage Systems in Spain: A Diagnosis
(MDPI, 2021)[Abstract] Sustainable urban drainage systems (SUDS) were almost unknown in Spain two decades ago; today, urban drainage in the country is transitioning towards a more sustainable and regenerative management in a global ... -
