Short summary

Recently, along the east coast of South Korea, seasonal beach erosion has been induced by structures which severely block the supply of sand from the upstream side. This study proposes a coastal solution that can predict the maximum indentation point in downdrift erosion formed downstream of groins by applying a parabolic bay shape equation (PBSE).
