geography coursework, anyone???

[Maarya]

for calculating the discharge of a river you need to do velocity x area, but how do i work out the area of a river??? i know you need to use the river cross-section, and i've got that, but i dont understand how you do it :grumbling

help!!!! anyone please!!!!!

i really appreciate your help, thankyou in advance.

[Maarya]

i would've aswell, but i had no other choice but to chose music, pe, dance etc so i did geog...its not too bad - u get to push the teacher in the river

help....anyone....i need to hand it in on monday

[deen_2007]

lol............i just didnt pay any attention to it...was too lazy about it...but i guess if i sit in the classes now...id probably be able to push the teacher in the th river too!!

(funny how when you leave a certain level in education..it is easier for u to understand it then & you also want to study it)

Ok, I have absolutely no clue, but, I found this online and maybe it will help you:

Measuring River Discharge

Hope it helps.

Wow, this is pretty...tough lol. This is why they don't do geography at GCSE level at my school. Good!

Well look at it from a logical point of view, using estimation. Area=Length x Width, so split up the river into parts and use that. if you find yourself with bends...I suggest you....think extra hard. Try using Area.Circle=PixRadius divided by 2. :confused: subhanallah...Some really hard stuff lol.

At the end add up all the areas you found. Apart from that I don't really know, unless there's some sort of universal eq. that brings light to this situtation...Google didn't help either

Hope that helps





Edit: That link is very good

PS.

you can use the equation and make 'A' the subject. for example:

Q=VxA

Q=A
V

Give that a try :confused: Which will only work if you have the value for Q and V grr! Maths is annoying

lol alhamdulillah...This hasn't got anything to do with GCSE maths though does it? cos if it is I'm done for

[Maarya]

nahh, dnt worry, i'm sure its just geog

[strider]

I was just about to suggest using the triangle formula. Those rock!

I hated geography. Good luck with your coursework!
