Geography field study

Looking for tips. Going to do the river option this year with the 6th years and it will be my first time to do a river study (option 1) transportation and deposition.
Seeing as I never did one of these in college what are the main things to cover.
Thanks in advance.

My first time as well. I'm going to do it at a meander. I'm going to look at depth across the river to show dep. I'm also going to measure velocity.

I'll get them to draw a sketch as well. I'm thinking of measuring sinuosity. This will prove its a meander and thus deposition as well.

As for transport...... Thinking of using lid of a biscuit tin to observe saltation. Then measure the ph of the water to show solution. Then take samples to let water settle and show suspended load.

Was thinking of something similar. Good shout on the meander. Was also thinking of sampling the bedload to study the size and shape of rocks.. Their roundness or lack of, could show evidence of attrition occurring during transportation

Good suggestions so far. You could also measure the gradient of the river banks using a clinometer. The inner bank of the meander showing gentler gradient indicates deposition over time. If you don't have clinometres, get them to make one using a plastic protractor, some string, a paperclip and a drinking straw. Works fairly well and you can mention the making of the clinos as part of your planning section.
