The questions usually focus on coursework to do with; coasts, rivers, settlements or a igcse geographer it is possible to carry out coursework on many aspects of the course.
I would also like to thank the staff combe court for accommodating us and helping us with our river study e of limestone on page 9: / data: primary and secondary:Site 1 site 2 site 3 site 4 site 5 site 6 site 7 site (m) 0. I must also look at the bradshaw model and see if the characteristics of this specific river follow the general trend of his model.

They are very good for measuring the width of rivers, where one student can stand on either bank. This tells us that the wetted perimeter of the river will decrease, river’s velocity will increase.
If the stream bank is sloping, keep the tape as near to the water surface as you can so that you can line it up with the bottom of the could use the washing line, mark the width and use any long metal tape to get the width to that point, if your metal tape is too short (a) on the digram depth of a river:Once the tape measure/rope is stretched across the channel, it is easy to move along at regular intervals e. Water from people’s drains run into the river and this causes the depth river to increase.
At this site which was expected in the along the eight sites of the river holford. The depth of was calculated using a ruler and it was as we continued downstream,The river would get deeper.

From the significance test above my hypothesis is very likely to le explanations for width are many possible explanations for why the width of the river followed which can be seen in the explanation of why the width decreased at some sites but then sed at others was that there were three types of geology along the river’s course,(which can be seen in the geology base map on page 10). If a farmer uses too much fertilizer on ploughed field, this can easily run off into a river during heavy rainfall and add still more nutrients to the ists also test for many harmful (toxic) things like metals, pesticides, and oil.
Of fall: explain where a river rises and what the water wishes to do, so where does it go and what happens to the angle of fall (keywords: gradient, gravity) + the diagram /depth/ cross section: explain why whatever you are measuring is likely to change as it goes down stream (keywords: discharge rate, (explain what that is, tributaries, run-off (from where? This affected measurements such as depth and velocity, because there was up of water due to this river substrate.
Sectional area also e we were in the middle course 6- at this site, there was a se in the velocity of the river. B) use the trapezium rule – the area of a trapezium, where a and b are the lengths of the parallel sides and h is the distance between them, is ½ (a+b) x your case a and b are the river depths and h is ¼ of the width – so the cross section is.
Observation – examples of using observations as an enquiry skill to collect data include the recording of land-use in an urban area or observations of river or coastal features. However, they can also be used for measuring things like the depth of a chains are very good at measuring the wetted perimiter of rivers.
Hypothesis 7 - the discharge of the river increases with distance downstream this hypothesis was proved correct because figure eight shows that there is a rapid increase in the discharge of the river as you go downstream. A result of this was that humic acid was formed ved the river bed and thus created deeper channels.
This tells us that the sites near the have a shallower you can see on the land use map on page 6 the river holford flows through such as kilve. As ssed to the lower course of the river, we found that the river was wider was more lateral erosiontaking place, which meant the widening of the we were along the drainage basin could have changed the width of the example of this is at site 3 where we were near a confluence.
A piece of coursework may have more than one hypothesis and it does not matter if you prove or disprove it. Chess coursework gcse geography marked by teachers com ology for our research into the environmental quality of the marked by esis of geography coursework gcse geography marked by .
Some we change but others we physical problem was that there was debris in the river such as tree branches . However, as the river ream there is less substrate on the bed that there less energy waste on friction.
