Résumé :	In this study I present data on wader abundance and diversity over a five-year period following the construction of an eco-engineered flood relief channel in Hong Kong. The concrete channel has hollow cells in its bed which allow retention of a silt/mud substrate. Twenty wader species have been recorded in the channel and both wader diversity and abundance have shown an increasing trend over time. The channel offers foraging opportunities to waders, which can be particularly important during winter and migration periods. The cellular concrete appears to provide microhabitats in the channel bed and this seems to be preferable compared with a homogenous concrete lining with no ecological niches.
