Geography investigation - The River Skirfare located in the Littondale region in the Yorkshire Dales National Park.

... SECTION 1 Hypotheses; Hypothesis 1; 'Bedload will decrease in its size and angularity downstream'. By this, I mean that the material being carried, eroded and transported by the river will be smaller and more rounded downstream, than the material upstream. Hypothesis 2; 'The efficiency of the river will increase as you look further downstream.' This is where the river's ability to carry and transport material is greater downstream, but not upstream. Hence, we can say that upstream, has a poorer efficiency, than that downstream. Hypothesis 3; 'The velocity of the river will increase further downstream.' This would mean that the further down the river you travel the greater the surface speed of the river. Gradient will also be of great use as there will be an inverse relationship between the two variables, velocity and gradient. The further downstream, gradient will start to decrease. In other words the land around the river will be much more level downstream, but steeper upstream.
