Being only constructed recently, there have not been a lot of published studies on the effects of marsh terracing. However, the existing results are promising. The terraces have a higher sediment accumulation rate compared to erosion, and are able to reduce wave strength by an average of 45%. The calmer waters allows sediment to settle which then promotes the growth of seagrasses which further hold down the sediment with their roots. Additionally, the terraces have been found to provide habitat for marsh wildlife such as seabirds and fish.
