David researches a temporary stream close by his place with the help of the CrowdWater app. He presents the Hamble Brook and its changes over time in this video:

In his article, published in Chiltern Environment he talks more about the stream and its specialty as a chalk stream – a stream heavly influenced by the limestone rich surroundings.


“Chloe’s research focuses on chalk streams within the Colne catchment, Hertfordshire, which have naturally intermittent and perennial reaches – which are influenced, in places, by abstraction and physical modification” (p 11).

Chloe explains how she used CrowdWater for her research on temporary streams, specifically chalk streams. She was interested in the plants growing around the streams and used the CrowdWater app to observe the current water situation. You can read more about it in the article:


In a Greenpeace article about climate change, Auria introduces the CrowdWater app. CrowdWater is a way for the public to participate in research. Auria explains in an interview why she likes collecting data for CrowdWater. In a short video on Facebook, you can take a closer look at the observations at one of her spots.


Some schools, such as the Kantonsschule Baden or the Kantonsschule Kreuzlingen, have learned about CrowdWater in their lessons. We present some of the results here (in German).
