Groynes are one of the most prominent structures that are used in shore protection to control the littoral
sediment transportation. This structure can be used submerged providing the necessary beach protection
without negative aesthetic impact. Although submerged structures adopt for beach protection, the
shoreline’s response to these structures is not well understood at present. The objective of this study is
to predict sediment transport in the vicinity of submerged groyne and comparison with non-submerged
groyne with focus on a part of the coast at Dahane Sar Sefidrood, Guilan Province, Iran where serious
coast erosion has occurred. The simulations were obtained using a one-line model, in this paper; a linear
model is presented to estimate shoreline deformation in the presence of these structures. The results of
the present study show that using submerged groyne can have a good efficiency to control the sediment
and beach erosion without causing severe environmental impact to the coast. The important outcome
from this study may be employed in optimum design of groyne systems in marine projects. Comparison
of the predicted results with those obtained through field measurements shows the efficiency of the
proposed model.
