### sec.31 Additional information about applicability of cross-section diagrams For any valley, a particular valley reach could contain a section of valley reach, or a section of watercourse within a section of valley reach that may be different to a valley reach and watercourse cross-section depicted in schedule 1 , parts 2 , 3 and 4 . The cross-section of part of a middle valley reach of a particular watercourse might more closely resemble what is typical for an upper valley reach cross-section, and the cross-section of part of a lower valley reach of a particular watercourse might more closely resemble what is typical for a middle valley reach cross-section. Accordingly, a cross-section diagram could be used to help in the location of a non-tidal boundary (watercourse), regardless of the valley reach in which the section of watercourse under consideration is located.
