Abstract: |
Improved procedures for predicting beach response to wave action are needed to optimize nourishment projects, reduce the volume of sand required and estimate performance. To date, no model has been able to satisfactorily represent the evolution and final profile of the beaches of well-graded sand, nor have experiments addressed the non-idealized case of sediment sorting across a beach composes of well graded sand. Therefore, no reliable and proven method exists to predict the dry width of a beach with multiple grain sizes. The equilibrium beach profile equation developed by Robert G. Dean is widely used but should be treated like an idealized beach representing a kind of “average” beach. Its limitation to beaches with a unique grain size has been demonstrated several times. New forms of the equation regarding varying sediment sizes have been tested with differing results. Due to the lack of studies about the subject, theses attempts considered arbitrary variations of the grain sizes with offshore distance. To address the deficiency in information related to well-graded sediments, an experimental program has been carried out. This thesis describes the set of experiments performed in the laboratory using a wave tank in which a well-graded sand beach was simulated. Data collected and analyzed included sand samples, beach profiles, and wave characteristics. The sand samples were taken from different locations at different intervals within the 24 hours duration of each experiment. With these results and use of the Dally wave transformation model, an analysis of the dissipation of energy per unit water volume across the beach is presented. The dissipation of energy per unit volume was the original concept associated with the equilibrium beach profile in which a single value is associated with each diameter. However, results obtained herein support a relationship of the dissipation with the particle Reynold Number. A new approach to the problem based on this result is also presented. |
