This view looks up the river towards Loch an Nid, seen in photograph three. The river here has changed its course; the short stretch of water in the centre of the photograph shows where the river used to flow. The river here is beginning to show signs of a river in its middle course.
Task A
5.1 What is the term for the feature in the centre of the photograph left when the river changed its course?
5.2 Under the headings of gradient (slope), width, depth, valley floor,describe the difference between a river in its upper and middle courses.
Task B
5.3 Using the map for extra information, label a sketch of the photograph to show river features, names given on the map and any other geographical features.
(089791, southwest)
This close-up of the feature shown in the previous photograph shows it is some time since the river flowed along this course. It is slowly filling and becoming a part of the river's floodplain.
Task B
6.1 Describe the process of infilling that is taking place.
(075790, northeast)
The river here is meandering on a broad floodplain. In middle right can be seen the semi-derelict house of Achneigie.

This general view of Eilean a' Chip is included to show the process of change that took place between 1994 and 1998. The river in 1994 was taking the course shown on the map but was in the process of cutting through the meander along the straight line. By the time this photograph was taken, in 1997, the change was almost complete. It would seem that this change in the river's course has been a regular occurrence.
