Quantifying the role of individual flood drivers and their correlations in flooding of coastal river reaches
(Springer, 2019)[Abstract:] Flooding in coastal river reaches is the result of complex interactions between coastal and inland drivers. Flood hazard assessments need to consider how these drivers interact in space and time, for which a ... -
Application of an Analytic Methodology to Estimate the Movements of Moored Vessels Based on Forecast Data
(MDPI, 2019-09)[Abstract]: A port’s operating capacity and the economic performance of its concessions are intimately related to the quality of its operational conditions. This paper presents an analytical methodology for estimating the ... -
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) ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 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 ... -
MERLIN: a flood hazard forecasting system for coastal river reaches
(Springer, 2020)[Abstract:] This study presents MERLIN, an innovative flood hazard forecasting system for predicting discharges and water levels at flood prone areas of coastal catchments. Discharge forecasts are preceded by a hindcast ... -
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 ... -
New insights to study the accumulation and erosion processes of fine-grained organic sediments in combined sewer systems from a laboratory scale model
(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 ... -
Assessment of the performance of drought indices for explaining crop yield variability at the national scale: Methodological framework and application to Mozambique
(Elsevier, 2020)[Abstract:] Droughts are one of the most damaging and complex natural disasters in the world, and they frequently affect agricultural production. Drought monitoring is essential for decision-makers seeking to minimize the ... -
