Using a tape measure, hold one end at the point where the water meets the bank one side of the channel.
Ensure the tape is not twisted pull the tape measure across the river and measure to the point where the water meets the bank directly opposite. `"Width" = 1.20m` so `"width"/10 = 0.12m or 12cm` Use this interval to measure at 9 equally spaced points across the channel.
With a flow meter it is possible to obtain a measure of velocity in the field – if you do not have access to a flow meter you can take some measurements using a float and calculate velocity using the formula `"Velocity" = "Distance"/"Time"` Dog biscuits make good floats as they are not too easily moved by wind and break down in the water if swept away.
The easiest way to accurately record the locations of your sampling sites is to use a GPS – there are many different Smartphone apps that will allow you to do this.
Data collected in the field provides an invaluable contemporary and historical resource that can form the basis and inspiration for further studies.
Assist future students and at the same time enhance your University entrance application and Curriculum Vitae by publishing the data from your Barcelona geography fieldwork on this site.' by Jung Hoon Lee and Mitzi Laszlo van Harreveld, Kensington School, GCSE Geography Edexcel Syllabus A) can be found in the menu to the left. A Level coursework examples include 'Has the Universal Forum of Cultures improved the quality of life in La Mina, Barcelona? ' by Ross Jones and 'How and why does the quality of life differ between the Diagonal Mar and La Mina districts of Barcelona? Also, I can only think of one hypothesis which is River A is more polluted than River B.Why don't you do: 'As velocity and riverload increases, so does the width of the channel' If you wanted to do the one about pollution levels you could ask your council for pollution level data for the river, it's what we had to do then talk about factors affecting the leels in different sections of the river e.g river runs next to agricultural land or through an urban area. Luckily the Geography department at my school were helpful and so basically gave all the students doing Rivers a guide as to what to do, write, explain etc. Hopefully your teacher will give you some kind of booklet like this, unless you're expected to be completely independent on this piece of work?In justifying your choice of the variables you have measured it can be helpful to consider the linkages between the different river variables.It is not possible to measure river discharge directly in the field.Your coursework will be credited to you and will remain your intellectual property.It cannot be copied or used in any way without your express written permission.In situations where access is more limited you may have to take a more opportunistic approach to sampling – however in this case it is sensible to get as close as possible to a systematic sample as possible.An alternative approach would be to base your sampling on areas where you might expect significant changes in river discharge – By choosing sampling sites immediately downstream of confluences you may be able to identify the significant changes in discharge and consider the impact of stream order.
