 == 2.2 Definition of the co-ordinate system ==
 
-The co-ordinate system is defined as follows. X is defined as zero at a position 56 cm upstream from the downstream end of the straight channel. This is the position that the basal ADV probe (ADV1) is located at when the traverse is at position X1. Position X4 (at the apex of bend 2) is 7.01 m downstream of position X1. The Y-direction is defined relative to the local channel cross-section at any given X-position. The zero position is defined as the right bank of the channel, as looking downstream. The z-position is defined locally from the bed of the channel, for any given XY position, with zero representing the bed.

The z-position is defined locally from the bed of the channel, for any given XY position, with zero representing the bed. The channel system is positioned relative to the centre of the Coriolis table as follows. The centre of the Coriolis table is 13 cm upstream and 45.5 cm to the right hand side (as looking downstream) of the inner bend wall apex position of the first bend [all measurements are taken from the outer edge of the channel wall].
