Charting the Irrawaddy with balloons and GPS trackers

A team of TU Delft researchers and students travelled to Myanmar the last week of January 2017 to chart the flow of the country’s largest river, the Irrawaddy. The delegation took with them 15 specially-made GPS trackers and 400 balloons with LED lights to help complete the task. Once the devices were put to water, the team tracked their progress as they travelled several hundred kilometres downstream. Using this method, the researchers collected data on the variations in the flow rate of the river. The team also measured the quality of the water. The data will be used to calibrate a model of the river’s hydraulics and water quality. The team’s progress could be followed on the TU Delft Instagram account,  via #theweekof, and on the account of one of the participating scientists Rolf Hut. Their combined posts are listed below.
