Fishermen predict flooding
A flooding costs billions.
Scientists can predict a flooding or droughts using sensors in a river or ditch. With the new sensing pair of waders, fishermen around the world, help scientists.
This new technology is a lot cheaper.
To determine where groundwater reaches the river or ditch, geoscientists developed distributed temperature sensor technology to predict a flooding.
Why do they want to know were groundwater reaches the river or ditch? Knowing where groundwater flows into the river or ditch helps to predict a flooding after heavy rainfall. Or it indicates coming droughts.
Expensive light technology
By sending light through a fiber optic cable (which already lays in the ditch), scientists are able to measure local temperatures. Usually groundwater is colder than the ditch water, so the measures determine where the groundwater flows into the ditch. The technique works, but is expensive.
Cheap alternative to predict a flooding
Industrial designer / engineer Rolf Hut thought: What if we equip fishermen pairs of waders with temperature sensors? Fishermen around the world could impending droughts or floods. With their sensing pair of waders, they can give scientists an additional source of information on stream-water–groundwater interaction.
Their cell phones could collect temperatures and GPS data and send it to a central platform. The plan worked. The research showed that data from temperature-sensing waders worn by the public and shared with scientists, can be used to decide where the most interesting places are to do more detailed and more expensive research.
A prototype temperature-sensing pair of waders is introduced and tested
Hut demonstrated his idea in 2015 at a conference in Vienna. After that, he improved the measurement system and did experiments. Yesterday, his findings were published in the scientific journal geoscientific instrumentation Methods and Data Systems.
