I use a lot! I have a rain-logger which measures how much it rains. I have a water-logger that measures how deep the river is. I also have something called a “turbidity sonde” that measures how clean the water is. The most complicated thing I use is called an “acoustic Doppler profiler”, it’s a small boat on a rope that I pull across the river and it draws a detailed picture of the water in the river on my computer.
