The girlwhoknewtoomuch would you be able to help me with my aqa gcse controlled assessment on rivers, its about why rivers change as you downstream?

What are you supposed to write about in the interpretation?

it's quite hard to remember what i did as i did this almost 2 years ago now, but i think the interpretation is where you write about what your results from  your data show you. have you done your presentation part yet? if you have then the interpretation will be a lot easier. the presentation is the bit where you put all your data into graphs and things.

i'm finding it hard to remember what i wrote, is the interpretation the bit before the evaluation, cause i know in the evaluation you have to say what was good and bad about your investigation and the data you got from that, so i think the interpretation is asking you to explain what your results show and why, so if your data shows you that the bedload size gets smaller and the velocity of the river gets quicker you can link these together by this relationship. try to link data together and say why and then link this back to your orgininal hypothesis, so if the velocity, discharge and bedload all increas/get smaller then say how this could mean that the river can get wider as it goes downstream.

hope this helps, if you need anything else, ask and i'll try to help you.

how long does it have to be and do you have to write about every table and graph?

mine was around 2 pages of a4, but i did write too much, i think you do need to mention them, if some graphs show the same results then you can mention them together

Could you read this and tell me what you think?

Figure 2.1 displayed trends for water width, depth and the wetted perimeter. My primary evidence suggests that the water width increases as you downstream. Site B has a water width of 1.3m, site C has a 0.7m increase than site B meaning site C has a water width of 2m and site D has a water width of 8.27m. This clear display in increase of water width is due to the increase in discharge via tributaries. As discharge increases the cross sectional shape and velocity will also increase, with the stream becoming deeper and wider which is shown in figure 3.1. This shows there is a clear link between the cross sectional shape and the water width of a river. The increase in water width is also suggested by the Bradshaw model. Increase in velocity also means increase in load, meaning hydraulic action, abrasion, solution and attrition will take place, making the river channel erode laterally. Water width is also presented in a bar chart in figure 5.1.

My results for the average depth of the river also show a similar trend in figure 2.1. Site B is 0.091m deep, Site C 0.088m and Site D 0.36m. Site C again is another anomaly and does not follow the trend of the Bradshaw model as the depth is supposed to increase downstream. The idea of the width and depth increasing due to the increase in discharge is also supported by figure 3.1. The cross section of Site C is much deeper and wider than Site B suggesting that the discharge is also increasing downstream causing the width and depth to increase as well. Also due to the 4 methods of transportation - traction, saltation, abrasion, solution and suspension the river is eroded vertically.  .Average depth is also presented in a bar chart in figure 5.2.

From figure 2.1 I can also see an increase in wetted perimeter downstream. With a 1m increase between site B to site C from 1.5m to 2.5m, site D is 8.37m deep. The reason behind this is also due to the link with hydraulic radius. At the source of the river (upper course) there is little hydraulic radius meaning, less transportation occurring because the river is not efficient. However, near to the river mouth (lower course) there is more transportation occurring because the hydraulic radius is high. More transportation occurring means bed material is moved downstream, increasing the perimeter of the bed that is in contact with the water increases. Also, there is greater lateral and vertical erosion. Since the width increases due to the 4 erosion processes and the depth increases due to the 4 transportation processes, which again means the perimeter of the river bed in contact with the load also increases, smoothing and widening the river bed. Wetted perimeter is also presented in a bar chart in figure 5.1.

thats good. did you do any measurements of bedload size? if you did you could comment on how the size of bedload decreases as you travel downstream and if you have any graphs that don't fit your hypothesis talk about them, otherwise, i think thats fine. how long do you have to do this? and can you get your teacher to check it?

Yeah i took measurements for pebble long axis, sphericity and roudness but my results are well messed up :S but i have to link it back to the bradshaw model which only has bedload size not sphericity or roudness so im not sure about what im supposed to write. Instead of a hypothesis i only have a question which is how the river changes downstream. do you think i need a hypothesis as well? we have 2 weeks and no she isn't going to check it

oh if you have a question you don't need a hypothesis, it's just that i had a hypothesis not a question. if you have any pictures you can annotate them to show what features of the river changes, such as slip off slopes, steep river cliffs etc. to help to show how the river profile change as you go downstream. you can mention your bedload results in the evaluation saying how your results aren't reliable. i'm not sure about maps, the only map I used was right at the beginning of the coursework showing the location of the river, you don't need to mention that in the interpretation

I think you are doing things well, your methods are well explained and your interpretation sounds good. your evaluation is missing, is this because you ahven't finished it yet? and you might like to increase the size of the text in places, but apart from that is good, you should get a good grade for this.
