How Do Modeling Choices and Erosion Zone Locations Impact the Representation of Connectivity and the Dynamics of Suspended Sediments in a Multi-Source Soil Erosion Model?
(Copernicus GmbH, 2021)[Abstract] Soil erosion and suspended sediment transport understanding is an important issue in terms of soil and water resources management in the critical zone. In mesoscale watersheds (>10 km2) the spatial distribution ... -
Hydraulic modeling of bridges in two-dimensional shallow water models
(American Society of Civil Engineers, 2022)[Abstract:] The backwater effect generated by bridges can significantly increase the risk of flooding. In this work we compare two different methods to include the effect of bridges in two-dimensional (2D) shallow water ... -

Improving the predictive skills of hydrological models using a combinatorial optimization algorithm and artificial neural networks
(Springer, 2023)[Abstract:] Ensemble modelling is a numerical technique used to combine the results of a number of different individual models in order to obtain more robust, better-fitting predictions. The main drawback of ensemble ... -
Incorporating Antecedent Moisture Conditions and Intraevent Variability of Rainfall on Flood Frequency Analysis in Poorly Gauged Basins
(Wiley, 2018)[Abstract:] Rainfall-runoff models are frequently used for the prediction of flood discharges from extreme rainfall data in poorly gauged basins. However, the conventional methods used to estimate the frequency of flood ... -
Influence of sediment characteristics on long-term hydrology and water quality behaviour during the clogging process of a permeable asphalt
