However, flow attenuation is dependent on factors such as reef submergence, width, and complexity. Yet the relationship between elements of the oyster reef landscape and flow attenuation is still not fully understood, making it challenging to design nature-based solutions for coastal protection. The topographical roughness characteristics of Sydney rock oyster ( Saccostrea glomerata ) reef surfaces were investigated using spatial statistics extracted from digital elevation models. Oyster agglomerations were classified into three distinct structural classes (Patch I, Patch II and Cluster) to differentiate intra-reef complexity. Patch I types had greater roughness heights (total roughness height, k t = 74 ± 10 mm) than Patch II (k t = 56 ± 9 mm). Benthic flow instantaneous velocity readings were taken at windward, leeward and on-reef points for each delineated structural class. Of the samples examined, observations were made that oyster beds with higher k t values experienced greater flow reduction. While a direct link cannot be established, with future work, the results of this study can assist in achieving meaningful targets for patch-scale oyster reef restoration substrate. oyster reef Saccostrea glomerata bed roughness flow attenuation Full Text Supplementary Files 2024EstuariesCoastBarclaySupplementalMaterial3.pdf Cite Share Download PDF Status: Published Journal Publication published 23 Apr, 2025 Read the published version in Estuaries and Coasts → Version 1 posted Editorial decision: Accept as is 04 Apr, 2025 Editor invited by journal 31 Mar, 2025 Editor assigned by journal 31 Mar, 2025 First submitted to journal 31 Mar, 2025 You are reading this latest preprint version Research Square lets you share your work early, gain feedback from the community, and start making changes to your manuscript prior to peer review in a journal.
