At 50m intervals a 'spot-check' is conducted to record specific details about bank and channel physical attributes, man-made modifications, land uses and vegetation structure. Surveys conducted prior to 2003 should not be compared with surveys conducted after 2003 as survey methodology changed significantly in 2003.
