Hydrologists collect stream measurements to ensure we are not using our water resources too quickly or in unsustainable ways. With a few household items, you can collect river measurements too!
Different rivers naturally have different planforms – and that’s a good thing! You will find healthy streams and rivers with a variety of different natural planforms – no one planform is necessarily better than the others. What is best is for a river to be in as close to its natural state as reasonably possible.
