For this paper a team of researchers from all corners of the Netherlands joined efforts to measure the effects of a large-scale biodegradable reef. Short term results showed that the artificial reefs could reduce wave heights up to 60% and on average 30%, compared to the adjacent bare tidal flat, despite being placed in a highly exposed area. Also, it was clear that biodegradable reefs were able to accrete sediment at a local scale, during the time the ephemeral reefs persisted. In addition, surrounding sediment properties were not affected by the presences of the structures. No long-term effects could be established, because the set-up was not sufficiently resistant to persist long term.
