:D :sl:

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. :D

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 :mmokay:

Hope that helps :hiding:



:w:

Edit: That link is very good :p

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 :mmokay: grr! Maths is annoying
