SECTION C: ARTIFICIAL FEATURES




Indicate the number of artificial features in each category (major, intermediate or minor) occurring within the site. Tally the features as you walk along, add up the total at the end of your survey, and enter the number in the appropriate box using Arabic numbers.   Insert ✓ in the box to indicate ‘none’ if no artificial features are present.


You should take a photograph of any major or intermediate structure across the channel, with, if possible, a ranging pole alongside. Take pictures upstream and downstream of the structure if it appears to be causing a significant change in river character (e.g. a dam). If a structure contains features of interest (e.g. fish ladder in major weir), make a note in Section O, as well as taking a photograph. Photographs of weirs should be taken since the height, design and construction material will determine the impact on the river.


If you are unsure about the nature of a structure, make a note on the form and picture and ask for advice.


The figure below shows in plan-form the range of ‘major’, ‘intermediate’ and ‘minor’ artificial features that need to be recorded.
