Análise do rompimento hipotético da barragem de Ernestina
(1997) [Artigo de periódico]O rompimento de uma barragem é um evento que pode ocorrer devido a diferentes causas. A avaliação dos seus potenciais impactos é um processo preventivo que faz parte das ações de planejamento da Defesa Civil. Essa análise ... -
Dam-Break analysis : proposal of a simplified approach
(2021) [Artigo de periódico]Simplified methods are useful alternatives for prior analysis of the effects of dam rupture and can guide the decision-making process for carrying out more complete studies. In this context, a new simplified approach is ... -
Dam-break due to overtopping failure: experiments in homogeneous earthfill dams
(2024) [Artigo 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 ... -
Experiments on initial stages of development of dam-break waves
(2021) [Artigo de periódico]The initial stages of instantaneous dam-break waves are here evaluated spatially and temporally through 36 physical experiments. Different conditions were tested for downstream (J) and upstream (M) water depths and their ... -
A simple model of flood peak attenuation
(2024) [Artigo 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 ... -
Uncertainty assessment in hydrodynamic modeling of floods generated by dam break
(2018) [Artigo de periódico]The objective of the present work was to evaluate sources of uncertainty in dam break simulations for areas with contrasting characteristics: one in a narrow valley with high slopes, and another an open valley with low ... -
Use of large-scale hydrological models to predict dam break-related impacts
(2020) [Artigo de periódico]In this research study, the MGB-IPH (acronym for Large Scale Model in Portuguese - Modelo de Grandes Bacias) was used to simulate the propagation of a dam breach hydrograph estimated from predictor equations for the Três ...
