Dam-break due to overtopping failure: experiments in homogeneous earthfill dams
(2024) [Artículo de periódico]This work physically simulates the effect of low and high flow rates and filling times of reservoirs and rupture due to overtopping (caused by intense rains) of small homogeneous silty-sand earthfill dams. The experiments ... -
A framework to improve churn prediction performance in retail banking
(2024) [Artículo de periódico]Managing customer retention is critical to a company’s proftability and frm value. However, predicting customer churn is challenging. The extant research on the topic mainly focuses on the type of model developed to predict ... -
Submerged hydraulic jump : a computational analysis in different scales a computational analysis in different scales
(2024) [Artículo de periódico]Advancements in computational capabilities have enabled engineers and scientists to numerically model complex turbulent phenomena such as hydraulic jumps. This research assesses the capability of numerically simulating a ... -
Adsorption of the fungicide carbendazim on activated carbon: analysis of isotherms, kinetics, rapid small-scale column tests, and impacts of the presence of organic matter
(2024) [Artículo de periódico]The adsorption of the fungicide carbendazim (CBZ) on granular activated carbon (GAC) made from bovine bone was investigated in deionized water (DW) and DW with the addition of natural organic matter (DWNOM). The study ... -
Sub-daily flow alterations (hydropeaking) due to reservoir operations in brazil
(2024) [Artículo de periódico]International studies have focused on the hydrological impacts on an hourly or sub-daily scale that hydroelectric plants can cause through hydropeaking operations. However, this topic is still underexplored in Brazil, ... -
Analysis of hydraulic parameters in determining the occurrence of cavitation in the spillways of the Furnas, Luiz Carlos Barreto de Carvalho and Batalha hydroelectric power plants
(2024) [Artículo de periódico]The hydrodynamic conditions to which hydraulic structures such as spillways and stilling basins of dams are submitted under given conditions favor the occurrence of cavitation, damaging the concrete surfaces. This damage ... -
Sub-seasonal streamflow forecasts for hydropower dams in the brazilian eletrical interconnected system
(2024) [Artículo de periódico]Inflow prediction on sub-seasonal timescale have the potential for important contributions to the management of water resources in hydroelectric dam operations. These forecasts challenge the limitations of the medium-term ... -
Seasonal streamflow forecasting in South America's largest rivers
(2023) [Artículo de periódico]Study region: South America large basins (>5000 km²). Study focus: This work represents a first assessment of seasonal streamflow forecasts in South America based on a continental-scale application of a large scale ... -
A simple model of flood peak attenuation
(2024) [Artículo de periódico]A simple analytical model was developed for evaluating the attenuation of flood wave peak discharge. The physically-based model represents the flood wave along its trajectory, based on the diffusive model. Relative peak ... -
Most influential feature form for supervised learning in voltage sag source localization
(2024) [Artículo de periódico]The paper investigates the application of machine learning (ML) for voltage sag source localization (VSSL) in electrical power systems. To overcome feature-selection challenges for traditional ML methods and provide more ...
