Vietnamese and American researchers joined efforts to develop a satellite-based system approach to monitor and manage transboundary flooding.
The teams from the Viet Nam National Center for Water Resources Planning and Investigation (NAWAPI) and the University of Washington co-developed and implemented an advanced water forecasting system. Recently, Viet Nam launched the satellite-based system aiming to improve timely access to upstream reservoir information in transboundary river basins of the Red and Mekong rivers. The satellite-based system provides various ways to achieve this objective.
With the mass balance approach users can calculate reservoir storage and outflow with satellite data. The key inputs of the dam system are precipitation and inflow. Therefore, satellite precipitation data and hydrologic models provide…

The activation was requested by the Brazilian Disaster and Risk Management National Centre (CENAD). The country’s Ministry of Regional Development is acting as project manager for the activation.
A dam at an iron ore mine in the south-eastern town of Brumadinho collapsed, releasing a torrent of tailings. The large volume of sludge that spilled out of the dam then swept south west to Paraopeba River, burying the site’s cafeteria where workers were eating, as well as nearby homes and vehicles. The mud has reached a depth of 50 ft in some areas. According to media reports, 134 people were killed in the event, while another 199 are still missing.

Mudslides and floods triggered by sudden rain over the western area of the Brazilian state of Rio Grande do Sul have caused the Ibirapuita, Ibicui and Uruguai rivers to break their banks and cause widespread flooding.
The rains have swept away entire neighbourhoods in a mountainous tourist area near RioMetSul Meteorologia reported 497mm of rainfall in 72 hours in the state of Uruguaiana.
Over 2000 people have been displaced and moved to temporary accommodation as the floods damaged houses, blocked roads and water supplies were disrupted.
Local reports say the flooding peak in the city of…
