The fieldwork site is located on the Harthope Burn immediately upstream of Langlee cottage (grid reference NT963232). It is within the valley about 5km from the source. It is a site of Special Scientific Interest so must be treated with care.

On a national scale, Harthope Burn is in the north east of England with the nearest major city being Newcastle. It is near to the Scottish boarder and is about 35km west of the North Sea. (Fig1.4)

Method

Field Sketch (Fig 2.1)

The first thing to be carried out was the field sketch, this was drawn from the bridge looking upstream and then annotated to show features such as slip off slopes and river cliffs. A photo was also taken (Fig.
The first limitation encountered was during the river planning; the tape at the baseline was broken and so measurements began at 3m. This meant that 3m had to be taken off the results gathered so that they were accurate. Another major limitation was the presence of large boulders further upstream when the velocity readings were taken. Although there were no rocks in the area of water being worked on, there were large boulders just upstream which almost completely stopped the flow of water. This meant our results appear incorrect as the water was moving very slowly in an area where it should have been moving
