my life as a math word problem

Part A. If a PhD student runs a trickle of water overnight into a flume that isn't draining:

1. how many gallons of water will spill over the top of the flume onto the geology department floor?
2. how many gallons of water will leak out the flume seams onto the geology department floor?
3. how many gallons of water will the PhD student have to bail out of the flume the following morning between classes?

Part B. If the PhD student is bailing the flume with a 4 gallon bucket that doesn't have a handle at 4 gallons per minute, and the janitor is bailing the flume with a 5 gallon bucket that does have a handle at 2.5 gallons per minute, how long will it take for them to clean up the flume?

I had raked out the flume to set up a braided stream system, onto which I will plant sprouts in order to create a meandering stream system, and accidentally set up a Lake Bonneville system. Amazingly enough, despite the epic mess on a Friday morning, I did end up with a lovely braided stream, and as an added bonus, a lovely "flume delta".
