The aim of this field work was to study the long profile and its characteristics of the River Lym.
The velocity then drops at the mouth where it tends to deposit its load

This is the general long profile of the river where the gradient decreases as you go down the river. The source is highest point of the river basin which usually is a mountain.

The hypothesis of this field trip was to compare the long profile of a model river to the long profile of the River Lym and its characteristics. I came up with this hypothesis by researching into the geographical theory of the long profile of a model river and then wanted to compare it to a standard river in order to see which anomalies are present that is affected by nature or human activity.
Velocity then increases as you go down stream because the cross sectional area increases relative to the wetted perimeter which reduces friction despite the changes in gradient.

I carried out my field work along the River Lym in Lyme Regis which is on the South West Coast of England shown in the map.
