An Alternative Analytic Model of Beach Nourishment Planform Behavior

Mann, D.W., 2025. An alternative analytic model of beach nourishment planform behavior. Journal of Coastal Research, 41(4), 715–722. Charlotte (North Carolina), ISSN 0749-0208. This paper discusses a novel analytic approach to the prediction of beach nourishment planform evolution for a rectilinear planform of uniform width. Through the inclusion of an advective term in the governing equation, the planform evolution allows nonsymmetric evolution with respect to the initial centerline of the beach nourishment. The model attempts to offer practical benefits for coastal management by providing more accurate predictions of beach nourishment planform behavior. The model was compared to previously published shoreline evolution data with positive results. The model was used to simulate the long-term evolution of an actual beach nourishment project with mixed results. The paper also discusses the need for and methods to predict the advective velocity of a beach nourishment planform including several noncomplementary approaches.
