Implementing the Water Environment and Water Services (Scotland) Act 2003: Development of environmental standards and conditions limits - phase II: A Consultation

Amendments to paragraph 6 of Schedule 2 to the 2007 Directions

6. SEPA shall calculate the morphological condition values for the channel and banks of a river or part thereof in accordance with the formulae-

formula graphic

"A" = the river channel hazard score assigned in accordance with paragraph 4 or 5 above, as applicable;

"B" = the scale of alteration determined in accordance with paragraph 3 above;

"C" = the length of channel assessed; and

"E" = the river bank hazard score assigned in accordance with paragraph 4 or 5 above, as applicable.
