Take part in the Big River Watch
The Rivers Trust has a duty to look after the UK and Ireland’s rivers. A recent report by the group has found that many rivers were not in good health.

The Rivers Trust has a special project called Big River Watch in which the public help with scientific research. This project lasts for about seven days each time. The goal of the Big River Watch is to collect important information about the condition of rivers. The information would give scientists a clearer picture of river health.
To take part, you have to download the free Big River Watch app onto a smartphone. Then, go and choose a river to watch. You can go to your local river or somewhere new. After choosing a river, you need to find a place on the riverbank(河堤) or a bridge to watch what is going on for 15 minutes. In the end, you can send in information like the speed of the water and any pollution through the app.
