My hypotheses are:The character of the course of the River Bollin will change along its course to the mouth. The bed load will decrease and angularity of the materials found in the river will be reduced. The velocity

... Chapter I, Introduction On Monday the twenty first of June, 2004, we went on a field trip to study the characteristics, and formation of a river, how it changes in its journey from source to mouth, including its load Our aim was to learn first hand about how a river changes and forms on the different types of land found in its course. I predicted that as the river went downstream, it would become consistently slower, cover a much larger wetted perimeter, and that the stones in its bed load would become increasingly rounded as it was ground into sand. This is my investigation into the changing characteristics of a river along its journey from the source to the mouth. This will include using my geographical knowledge to create hypotheses and test them out using the results gathered from our many tests upon the river. All the tests were kept the same to
