- Water reservoir will be filled prior to starting the pump.
- After a 1-2 minute waiting period, the remaining visible air bubbles will be removed from the tubing connections
- An additional running time of 1-2 minutes will ensue before taking readings.
- Using a 600 mL beaker, the runoff from the head low water will be collected for 20 seconds.
- The sample will then be transferred to a 25 mL graduated cylinder and the volume will be recorded.
- This process will be repeated 10 times per trial.
- After a designated waiting period of (??) hours, another ten readings will be taken in the same manner. This will help determine if sand settlement causes fluctuation.
- The process will be repeated in its entirety for each sediment variation using identical parameters.

I think we should also try waiting overnight and see if the settling makes a difference then. Assuming both 1 hour and 24 our waits don't make a difference, we'll be able to just refill whenever. If they do, then it'll be longer and annoying.
