Human influence is strong here as the stream is confined to a narrow channel under the bridge. Velocity is increased and the strongest current is confined to the centre of the stream as it emerges from under the bridge.

Beyond the bridge, the channel is wide, shallow and straight. There is some disturbance of the flow due to pebbles and a few pieces of debris on the bed of the stream and due to the overhanging vegetation at the sides.
