“…In the past two decades, various types of the numerical models were applied to study the complexity of wave-vegetation interactions [24,[42][43][44]. For instance, by applying an improved Boussunesq wave model, the wave attenuation properties of flexible and rigid vegetation patches were systematically analyzed by Augustin et al [45] and Huang et al [22].…”

During severe weather, the runup of the devasting surges and waves can cause extensive damages to the coastal facilities and results in significant loss of life. Therefore, it becomes necessary to find reliable measures to reduce the wave runup in coastal regions. As a natural barrier to the shorelines, coastal vegetation has great potential to attenuate wave runup and to prevent the coastal communities from extreme floodings and huge land loss. This study numerically discusses the influences of the emergent vegetation patch on the runup processes of extreme wave groups by applying a nonhydrostatic flow solver. Influences of the major factors, i.e., water depth, peak wave period, significant wave height, and density and length of the vegetation patch, are analyzed in detail. Research findings indicate that the presence of the emergent vegetation patch can substantially dissipate most of the incident wave energy and effectively reduce the maximum wave runup heights of extreme wave groups at the sloped beach. It is hoped that the research results of this study will be helpful to the design of coastal soft protection measures.

“…The first analytical model that explicitly expressed vegetation-induced drag force used the Morison equation and schematised forests as arrays of vertical cylinders (Dalrymple et al, 1984;Morison et al, 1950). It has paved the way for modelling advanced physics in wave propagation, such as wave breaking, wave randomness and wave-current interaction (Hu et al, 2022;Hu et al, 2014;Losada et al, 2016;Mendez & Losada, 2004), and somewhat more complex forest configurations such as horizontal roots and extremely dense vegetation (Suzuki et al, 2012(Suzuki et al, , 2019. Further advancements that use a novel measuring approach can obtain generic drag coefficient equations for various flow and wave conditions and different vegetation types (Chen, Ni, et al, 2018;Hu, Lian, et al, 2021;Yao et al, 2018), and have successfully been applied in several modelling studies (Hu et al, 2019;Liu et al, 2015;van Veelen et al, 2020van Veelen et al, , 2021Wang et al, 2015).…”

Coastal flood risk will increase over the coming decades as sea level rise accelerates, storm patterns change and coastal populations grow. This will likely lead to a surge in costs to build and maintain reliable flood safety infrastructure. Hence, innovative nature-based solutions that use coastal ecosystems are gaining attention. Nature-based flood defence is a potentially sustainable and cost-effective solution to reduce coastal flood risk, that can be carried out with ecosystems such as mangrove forests, saltmarshes or coral reefs. Mangrove forests are increasingly studied for nature-based flood defence across the subtropical and tropical latitudes, as their sturdy vegetation can effectively attenuate flow energy from waves – surge attenuation with mangroves remains less well understood. Wider and denser forests provide more wave attenuation. As mangroves naturally fluctuate in size, so does their wave attenuation capacity. Consequently, to reliably estimate the safety of a mangrove-based flood defence, it is necessary to understand the long-term development of the mangrove forest. The studies presented in this thesis contribute important datasets and mechanistic principles that can be used to advance mangrove forest development models and estimate long-term flood protection capacity with coastal mangroves.
