Abstract
Sills (low–crested rubble mounds) are constructed to protect eroding bluffs and planted marshes in living shoreline projects (http://mycopri.org). Revetments are conventionally used to protect eroding shores and reduce wave overtopping and damage to backshore areas. However, revetment construction may result in loss of buffering wetlands. On the other hand, no established method exists to design the sill geometry (crest height, width and side slopes) and its distance from the eroding shore. This study compares the efficacies of the two different rubble structures with the same number of stones in order to clarify their similarity and difference for the purpose in reducing shore erosion and wave overtopping.
Highlights
Sills are constructed to protect eroding bluffs and planted marshes in living shoreline projects
The wave overtopping rate and sand overwash rate over the landward vertical wall were measured by collecting overtopped water and sand in a collection basin and a sand trap during each 400-s run
The increase of the still water level (SWL) by additional 4 cm resulted in the increase of the wave overtopping and overwash rates by a factor of 10
