This paper presents two application cases about long-term shoreline evolution modeling by using the GenCade shoreline model, which includes an empirical model for predicting volumetric changes of inlet morphology elements (shoals and bars). The two cases are to reproduce long-term variations of shoreline positions around Indian River Inlet, DE, and Absecon Inlet, NJ. Both included coastal structures (jetties, groins, piers, and outfalls) and non-structural protections such as beach fills, sand nourishment, sand bypassing operation, and dredging. This paper also provides the setup of complex model input parameters for configuring those structures and non-structural protection measures using GenCade interface built in SMS software. Simulation results indicate that the model is applicable to reproduce shoreline evolution with large variations due to severe erosion by storms and beach fills. The model is capable of predicting long-term evolution of inlet morphology elements including dredging on shoals and bars, which gives better understanding of sediment pathways through inlet shoals and adjacent shorelines. These capabilities for assessing impacts of structure and non-structural protection measures and inlet morphological changes will facilitate finding best solutions of combined erosion protection strategies on barrier islands.
