A couple pages back, someone mentioned calculating "rouse." Could someone explain what "rouse" is? I googled it, but all I could find was the last name of someone and "rouse belts," which are related to earthquakes...

My test was plotting points, contouring a map, circling a drainage basin and a couple questions. We didn't need our notes at all.

The Rouse number is a non-dimensional number in fluid dynamics which is used to define a concentration profile of suspended sediment and which also determines how sediment will be transported in a flowing fluid.

:oops: I can't believe I forgot to check wikipedia... Thanks though, that clears it up a lot.

Edit: How have you guys been getting your information? I've just been googling things and it seems like I'm missing some things... Do you guys use textbooks, and which ones?

The Rouse number is a non-dimensional number in fluid dynamics which is used to define a concentration profile of suspended sediment and which also determines how sediment will be transported in a flowing fluid. It is a ratio between the sediment fall velocity and the upwards velocity on the grain as a product of the von Kármán constant and the shear velocity .


However, as I asked before, should we learn about this? Will they ask us to calculate it?

i don't know if this has already been asked, but what sources is everyone using for world's largest rivers/lakes? i've looked at a couple of different sources, and each one listed them in different orders

I doubt this will be asked. It's very complicated physics. This event will stick mostly with geography. The hardest test I've taken was mostly IDing, types of lakes, and interpreting graphs. Even at my state level, the test was disappointingly easy and barely went beyond basic vocabulary...

Could someone please give me a good website for topo maps?

The test probably won't have many questions on topo maps though... Even if they do, they will probably be very basic things that you can use common sense and figure out.

On the contrary, my regionals test was just 3 topo maps, with a lot of questions about them.
It was pretty hard, but i managed to get 3rd :)
