Abstract:

This paper addresses the exploitation of mineral resources and suggests that an environmental management that meets a set of measures and mutual cooperation between public and private managers, civil society, and mining companies that exploit natural, renewable, and non-renewable resources is needed. Cooperation between managers and joint safety measures can prevent present and future accidents like the one that occurred in Mariana City in Minas Gerais State (MG). The questioning presented puts into discussion the disaster that occurred in Mariana City due to the rupture of the ore tailings da

On November 5, 2015, the rupture occurred of the Fundão dam of the mining company Samarco, located in the sub-district of Bento Rodrigues-MG, 35 km from the center of the Brazilian municipality of Mariana-MG, approximately 16.000 Olympic pools of mining residue circulated through the district of Bento Rodrigues in a period of only 11 minutes. The plume of this environmental impact extended approximately 800 km in the Rio Doce basin, between Minas Gerais and Espirito Santo.

Abstract:

Experimental and theoretical models are used to explore the break of a moraine dam by catastrophic erosional incision initiated by an overtopping wave. The experiments are conducted in a rectangular tank with an erodible barrier made from sand and grit. Theory combines shallow-water hydrodynamics with an empirical model of erosion. The models confirm that dams can be broken by a catastrophic incision. However, the displacement wave does not break the dam in its first passage but excites a long-lived seiche that repeatedly washes over the dam. The cumulative erosion of the downstream face by th

No entanto, o formato complexo da face da barragem, com regiões côncavas e convexas, não foi considerado devido às limitações das ferramentas empregadas.

Abstract:

To quantify the flood risks in cascade dam systems, it is critical to analyze the risk factors and potential breaking failure paths. In this study, Bayesian networks (BNs) were applied to create a flood risk analysis model for a cascade dam system. Expert experiment, historical data, and computational formulas were employed to estimate the prior probability and original conditional probability tables (CPTs) in the BN model; sensitivity analysis was used to ensure the original continuous breaking failure path in the system.

Abstract:

Tailings dam failure accidents occur frequently, causing substantial damage and loss of human and animal life. The prediction of run-out tailings slurry routing following dam failures is of great significance for disaster prevention and mitigation. Using satellite remote sensing digital surface model (DSM) data, tailings pond parameters and the advanced meshless smoothed particle hydrodynamics (SPH) method, a 3D real-scale numerical modelling method was adopted to study the run-out tailings slurry routing across real downstream terrains that have and have not been affected by dam failures.

Mine tailings containing trace metals arrived at the Doce River estuary, after the world’s largest mine tailings disaster (the Mariana disaster) dumped approximately 50 million m3 of Fe-rich tailings into the Doce River Basin. The metals in the tailings are of concern because they present a bioavailability risk in the estuary as well as chronic exposure hazards. Trace metal immobilization into sulfidic minerals, such as, pyrite, plays a key role in estuarine soils; however, this process is limited in the Doce River estuarine soil due to low sulfate inputs.

Abstract:

Macrophytes are plant organisms that live partially or totally submerged in water, being fixed and free. The Doce River is one of the main rivers in southeastern Brazil and, in 2015, it was hit by ore tailings from the Fundão dam burst in Mariana, Minas Gerais. This work aims to provide a floristic survey of macrophytes in the lower Doce River basin and to compare the species composition between lentic and lotic environments. Expeditions were carried out monthly from October 2018 to September 2019, in five stations in lotic and six in lentic environments. A total of 105 species belonging to 33

Abstract:

Unmanned aerial vehicles (UAVs; or drones) are an emerging tool to provide a safer, cheaper, and quieter alternative to traditional methods of studying marine megafauna in a natural environment. The UFES Nectology Laboratory team developed a drone-monitoring to assess the impacts on megafauna related to the Fundão dam mining tailings disaster in the Southeast Brazilian coast. We have developed a systematic pattern to optimize the available resources by covering the largest possible area. The fauna observer can monitor the environment from a privileged angle with virtual reality and subsequentl

Abstract:

An open reuse of public data and tools can turn the government into a powerful ‘platform’ also involving external innovators. However, the typical information system of a public agency is not open by design. Several public administrations have started adopting technical solutions to overcome this issue, typically in the form of middleware layers operating as ‘buses’ between data centres and the outside world. Open-DAI is an open source platform designed to expose data as services, directly pulling from legacy databases of the data holder. The platform is the result of an ongoing project funded

Abstract:

Tsunami run-up on the flat horizontal beach is studied by using the Benney shallow water equations. The dam-breaking flow includes vortexes, vertical shear flow and dissipation of momentum and energy on the front due to bore breaking. Propagating of hydrodynamics bores with breaking is analyzed by the mass, momentum and energy relations on the shock wave. Non dissipative wave front propagates faster than classical bore, while taking into account the dissipation and wave breaking leads to slowing of the wave front.

Abstract:

Purpose – The present work is a numerical study of a breaking dam problem. The purpose of this paper is to assess the effect of turbulence and surface tension models in the prediction of the interface position in a long-term analysis. Additionally, dimensional effects are analyzed by carrying out both 2D and 3D simulations. Design/methodology/approach – Finite volume simulations performed with the different models are compared between them and contrasted with numerical results computed using other numerical techniques and experimental data. Findings – The reported numerical results are in gene

PurposeThe major purpose of this paper is to answer the overarching questions of how multinational corporations (MNCs) address the multiple institutional logics of accountability and pressures of the field in which they operate and how the dominant logic changes and shifts in response to such pressures pre- and post-disaster situation.Design/methodology/approachIn-depth interpretive textual analyses of multiple longitudinal data sets are conducted to study the case of the Fundão dam disaster. The data sources include historical documents, academic articles and public institutional press releas
