Introduction
I am a Ph.D. candidate in Environmental Engineering at the Federal University of Paraná (Brazil) and a visiting Ph.D. student in the Environmental Physics group at the University of Koblenz-Landau (Germany). My research interests are in physical limnology and dynamic of stratified flows, with a focus on internal waves. https://sites.google.com/view/rafaelbueno/initial

Conference Paper
Full-text available
This study presents some applications of Dyenamic, an automatic dye tracing software which has is designed to analyze gravity currents from laboratory experiments and numerical models. Dyenamic tracks flow features of dye-coloured experimental setups. Through video observations obtained with standard cameras (e.g. professional cameras or cell phone...

An internal wave is a propagating disturbance within a stable density-stratified fluid. The internal seiche amplitude is often estimated through theories that describe the amplitude growth based on the Bulk Richardson number (Ri). However, most theoretical formulations neglect secondary effects that may influence the evolution of internal seiches....
Article
Interwave Analyzer is an open source software that provides detailed characterization of the dynamics of internal waves in lakes and reservoirs. It is based on well-established theories and empirical knowledge on internal waves and lake mixing and facilitates a general physical classification of lakes and reservoirs. As input data, the program requ...
Conference Paper
Full-text available
Observations have shown that gravity currents, a horizontal buoyancy driven flow generated by density differences commonly observed in lakes and reservoirs, may be an important agent of sediment resuspension, playing an important role for water quality of these ecosystems. We ran laboratory experiments in a rectangular tank to characterize the sedi...
Conference Paper
Full-text available
Environmental monitoring is an important issue to guarantee continuous preservation of the natural resources. Lakes and reservoirs are closed water bodies that often have an inherent dynamic, in which modify spatially and temporally many environmental parameters. One of the most important parameters to evaluate the water quality is the turbidity, w...
Conference Paper
Full-text available
Gravity currents are a common phenomenon that occurs in ocean, lakes, and atmosphere. Many studies have explored the propagation of gravity currents in ideal situations, thus avoiding the comparison between the well-known theory and specific situations, such as when the gravity current flows in a roughness bottom or in a stratified ambient. This pa...
Thesis
Full-text available
Internal wave is a oscillating disturbance within a stable density-stratified fluid. In stratified water basins, these waves have been detected and pointed as one of the most important process of water movements and vertical mixing. Most part of wind momentum and energy that cross the water surface is responsible to generate large standing internal...
Article
Full-text available
The vertical movements caused by internal waves in lakes and reservoirs have chemical and biological consequences for these ecosystems. The vast majority of studies that investigate internal waves are conducted on large lakes. There are just few researches that investigate this phenomenon on dendritic reservoirs. The purpose of this research was to...
Conference Paper
Full-text available
Resumo: Correntes de gravidade e de intrusão ocorrem quando há variações na massa específica em um fluido sob a ação de um campo gravitacional. Para o caso de correntes de gravidade em um experimento lock-eschange, as diferenças na pressão hidrostática fazem com que o fluido mais denso flua numa direção ao longo do fundo, enquanto o fluido mais lev...

Resumo: O transporte vertical de nutrientes, compostos químicos e microrganismos causado pela presença de ondas internas causam um grande efeito no estado trófico de reservatórios e, consequentemente, afetam de forma significativa a qualidade da água destes ecossistemas. Poucas pesquisas no cenário nacional e internacional buscam verificar a ocorrê...

Study effects of floating photovoltaic systems in reservoirs or lakes, such as: - effects on evaporation - effects on gas-transfer at the air-water interface, i.e. dissolved oxygen - effects due to reduction of radiation (less photosynthesis, less heating) - effects on reduced mixing and transport due to reduced wind-shear
