Hi there! I was wondering if anyone could tell me what types of mathematical questions are on DynPlanet? Like....what are the types of equations I should know, aside from the stream flow, discharge, load, floods, and recurrence intervals?

Well in C division there is the Chezy Manning equation... I can't think of too many more besides what you already posted.

Wow! We have a lot of events in common
.
Considering you're not in division C, no need to worry about Cheezy/Manning equations (or however you spell it).
Hydraulic head and hydraulic gradient is important to learn.
Also, just remember stuff like how to find surface area, volume, pressure, etc. because they might be on the test too.

Thanks mnstrviola

So does anyone know what the difference is between infiltration and percolation? If there is any. Thanks in advance

At my invitational, there was a contour map and well information.

Infiltration is runoff/precipitation getting past the top of the ground. After that, the water percolates through the ground as groundwater.
EDITed because of grammar fail.

Infiltration is also generally downward, whereas percolation can be in any direction.

Infiltration is the process by which water on the ground surface enters the soil.
Percolation concerns the movement and filtering of fluids through porous materials.
So basically, infiltration is when the fluid goes into the soil, and percolation is when the fluid actually reaches the water table and goes past it. Hope my answer is not too confusing.

I am suddenly in this event 24 days before Regionals. Exactly what are we supposed to do? (Other than read the rules and look at the stuff there, of course. More specifics, preferably.)
Also, since apparently I'm doing 7 other events, I won't have all that much time to study for this. What would you guys prioritize and study?
