“…Compared with the weighted summation of FVS and CVS, that is, p 1 q N (FVS) + p 2 q N (CVS) (−22.30, 16.74, and 55.79 mm 2 /s for M1VS, M2VS, and M3VS), the total net sediment transport rate is clearly enhanced (7.18, 58.03, and 79.24 mm 2 /s for M1VS, M2VS, and M3VS) mainly because of the variation of the net sediment transport rate for the fine fraction. The total net sediment transport rates between FVS ( q N = −48.32 mm 2 /s) and M1VS ( q N = 7.18 mm 2 /s) also show that 20% coarse fraction can reverse the total net sediment transport from negative to positive, which is essential for beach protection under erosive conditions (Srisuwan et al., 2015).…”

“…The morphodynamic problems also depend on the sediment size distribution because the effect of size gradation on the morphodynamic processes mentioned above can only be involved by considering the sediment transport rates of different size fractions (van Rijn, 2007; Srisuwan & Work, 2015). Subsequently, the improved parameterized formulae (van der A et al., 2013; Wu & Lin, 2014), process‐based models (Caliskan & Fuhrman, 2017; Kaczmarek et al., 2022), and morphodynamic models (Broekema et al., 2016; Srisuwan et al., 2015) are developed for graded sediment. The graded approach divides the mixture into several size fractions and employs the size of each fraction to the uniform sediment equations with a correction factor to account for the fractional interaction (Day, 1980; Egiazaroff, 1965).…”

At high sediment transport intensities, the oscillatory ripple loses its height and the bed becomes flat, and sediment motion then occurs as a sheet within a few centimeters near the bottom (Hassan & Ribberink, 2010). Sheet flow study is of considerable importance to coastal processes, as it can cause substantial morphological evolutions during severe hydrodynamic conditions over a short time scale (Tan & Yuan, 2021). Sheet flow transport in the coastal area is mainly influenced by the intensity of hydrodynamic forcing and the sediment properties (i.e., size, density, and shape) (Durafour et al., 2015). The heterogeneity of sediment properties is important to sheet flow transport (de Meijer et al., 2002), and this paper only focuses on the heterogeneity of sediment size. Many sediment beds have wide-size distributions, and the distributions may not be lognormal and tend to be negatively or positively skewed (Mohtar et al., 2016). Non-uniform sediments are also generally found in nearshore projects that involve the mixing of multiple types of sediment (e.g., beach nourishment and dredged material disposal) . The non-uniformity of grain size plays a very important role in the sediment movement caused by wave motion (Holland & Elmore, 2008). Massive sediment transport occurs in the surf zone and the swash zone, where graded sediment bed moves primarily under the sheet flow regime (Harada et al., 2015;van der Zanden et al., 2019). Hence, ascertaining the mechanism of oscillatory sheet flow for graded sediment is essential in coastal sediment dynamics.

Laboratory beach profile dynamics and responses to changing water levels with and without nourishment

This thesis presents the results of reduced-scale, laboratory wave flume physical model experiments. Following Bruun's (1954 and 1962) original proposal, Sea Level Rise (SLR) is expected to lead to cross-shore losses of sand volume from beaches. While some field studies have documented some of the characteristics anticipated with profile response to SLR (i.e. loss of beach volume and shoreline erosion), until this research commenced, there had been no Firstly, thanks must go to each of my research advisors. Professor Tom Baldock for his advice, support and guidance throughout this process. Professor Peter Nielsen for his support and encouragement to investigate various aspects of beach dynamics that interested me. Dr David Callaghan for his guidance and support in helping me appreciate many aspects of numerical analyses. I have learnt so much in my time at UQ, and I feel very privileged to have had the opportunity to work closely with each of you. Thank you also to Dean Patterson, for your encouragement and regular feedback at the coastal research group meetings. Thank you to all other members of the UQ coastal research group, it has been a pleasure to know you all and learn about your respective areas of research. Thanks to Mr Jason van der Gevel and Mr Stewart Matthews for all their assistance in the hydraulics laboratory and maintaining the wave makers, ensuring smooth operation over the thousands of hours I logged on them. Thanks to Dr Van Thuan Nguyen for his assistance in developing and debugging the electronics and software for the laser profiling system. Thank you to Ms Sheng Wu, Ms Chase Bawden, Ms Laura Beckingham, Dr Tomoko Shimamoto and Dr Florent Birrien for their assistance in operating the wave flumes and collecting profile data. Special thanks must be afforded to my wife, Lizzy, for her love, understanding and unwavering support, without whom, I would not have undertaken this project. Elise, you arrived halfway through my candidature and have brightened every day since, providing an endless source of inspiration and most welcome play-breaks.
