... What changes have occurred in the channel of the river Ely as it flows downstream This section will highlight the correlation of data and try to explain why certain features of the river channel changing, affects other features of the river. The cross-sectional maps and graph 4 show how the river widens as it deepens. E.g. Site 1 C.S.A is 0.53m square and at site 8 it is 25.2m square Diagram to show the difference in profile at different points of the river.
