    Well I would talk about all of that but then link it back to the cross profile, for example, in the upper course of river, higher level above sea level, therefore more gravitational potential energy, so rates of vertical erosion are higher than lateral rates, therefore channel will be narrow etc... As you go to the middle course, river effected less by gravity so there is less GPE and so lateral rates of erosion are more dominant than vertical, therefore channel is wider etc...

    Well meander is the natural bend in a river

    Meander belt is a phrase I haven't heard of :s is it a question in an exam?

    Apparently it's the total width across which the river meanders

    damn! thanks for pointing that out planning to spend tomorrow continuing revision of the rivers/coats topics so I shall make sure I know that by the end of tomorrow

    Is there any mention on what it means?

    Long profile is the profile from source to mouth.

    Cross profile is like if you went to one part of the river and cut a slice and you looked at the banks and the curvature of the river etc.

    (Original post by homefind)
    Long profile shows how the gradient/height above sea level changes over the course of the river

    Cross profile shows the characteristics of the valley/river channel over the rivers course (for example, upper course = narrow v shaped valley etc....


    I think that's right

    What are eddie currents? Is it turbulent flow formed from water going over more frictional stuff like rocks?

    I googled it came up with random physics coils etc

    Well I'm not one of the people you asked but I'm doing this section in the exam too! As far as I know Eddy currents are turbulent flow, yeah They're like circular water currents... I think!

    Ye turbulent flow is caused due to friction, hence in upper course when there is a lot of friction you get a lot of turbulence.

    Eddie Currents - am I right in thinking its just another name for helicoidal flow?

    Hmm seems legit, anyone want to add to that I think we're right!

    Just thinking that in bold right now sherlock


    Ok one more question
    Explain one way in which people can cause flooding ive got urbanisation etc etc, buttttttttt


    "Building bridges may constrict the flow, encouraging the build-up of water and flooding. "

    I thought if you build a bridge it goes over the water so it doesn't affect it??? Explain please

    nope it is do with cross proifle of rier downstream

    ANd one more question try out june 2011 question 1a ii)

    Explain the formation of landforms show in in figure 1

    It says in the MS

    "Level 2 (Clear) 5-7 marks
    Seeks to explain the sequence of the formation of the landforms – waterfall and
    gorge.
    There is some reference to both landforms, although one may be dealt with in
    greater detail. There will be greater reference to gorge through the level.
    Sequence is clear and there is reference to specific processes, such as
    abrasion.
    Appropriate geographical terminology is used."

    What does that even mean do I have to keep on quoting gorge each time?
    Why?????

    I thought a gorge was just A deep narrow passage with steep rocky sides; a ravine.

    Okay well you have urbanisation, deforestation, farming (affecting soils etc..)

    Ye that's a hard one to get around, but I think it's trying to get you to think of what would happen during a flood, so I know for example, in Boscastle during the flooding the bridge restricted the huge discharge of the river causing debris like cars and rocks to get caught up behind the bridge, leading to the water breaching the banks and going elsewhere (severely flooding the village)

    That's what a gorge is yes, but it also shows how far the waterfall has retreated, not too sure why you would be referring to the gorge more than the waterfall though I would be referring to waterfall more probably. Unless the 'referring' part is to do with the picture I.e describing some characteristics of the gorge shown in the picture, maybe?
