A Combination of A Shoreline Evolution Model and A Wave Crest Model on T-Head Groin Structures With the Breaking Wave Effecf

Abstract

Beach erosion is a naturally occurring phenomenon that occurs when the transfer of material away from the beach is not balanced by the deposit of new material on the shoreline. Beach erosion have always existed and have influenced the shoreline shape. This is a problem that contributes to the loss of shorelines. Structures invented to prevent beach erosion, such as seawalls, groins, and breakwaters. To avoid coastal erosion and sedimentation, a groin and a sea wall were constructed. Shoreline evolution analysis is being used to research the future topography of the beach. Beach erosion and beach deposition research requires a qualitative analysis of the model shoreline behavior with respect to the driving process. In this research, we focus on the effects of the T-head groin structure on shoreline evolution. The average wave crest impact is analyzed for eight sizes of T-head groin construction. An initial condition setting technique and boundary conditions techniques, as well as the structural impacts of the T-head groin, are discussed. Each year, the shoreline evolution is approximated using the traditional forward time centered space techniques and the unconditionally stable Saulyev finite differential techniques. The calculated impacts of shoreline evolution for eight different T-head groin sizes were consistent with the wave crest impact model.
