“…Another important parameter is the vegetation's mean stem diameter (d), which can also be evaluated as a function of z. Models for steady flows through rigid vegetation (Belcher et al, 2003;Guannel et al, 2015;Nepf, 2012;Temmerman et al, 2005b) often represent the hydrodynamic drag force F D per unit volume, which acts to dissipate currents, using the formula…”

“…Empirical information about spatial variation in vegetation density or reef dimensions rarely exists across a sufficient geographic extent needed to inform large‐scale development and conservation decisions . Thus, to be decision relevant, coastal protection models often need to be parameterized using summarized values from ecological studies in similar or nearby areas …”

“…Despite the recent surge in research, critical gaps in the science remain for inspiring and informing broad uptake and implementation of natural and nature‐based solutions. In particular, the importance of ecosystems can vary considerably with geomorphic setting, intensity of the hazard, habitat characteristics, socioeconomic factors, and management context . How much protection can natural habitats provide, under what conditions, now and in the future?…”

Interest in the role that ecosystems play in reducing the impacts of coastal hazards has grown dramatically. Yet the magnitude and nature of their effects are highly context dependent, making it difficult to know under what conditions coastal habitats, such as saltmarshes, reefs, and forests, are likely to be effective for saving lives and protecting property. We operationalize the concept of natural and nature-based solutions for coastal protection by adopting an ecosystem services framework that propagates the outcome of a management action through ecosystems to societal benefits. We review the literature on the basis of the steps in this framework, considering not only the supply of coastal protection provided by ecosystems but also the demand for protective services from beneficiaries. We recommend further attention to (1) biophysical processes beyond wave attenuation, (2) the combined effects of multiple habitat types (e.g., reefs, vegetation), (3) marginal values and expected damage functions, and, in particular, (4) community dependence on ecosystems for coastal protection and co-benefits. We apply our approach to two case studies to illustrate how estimates of multiple benefits and losses can inform restoration and development decisions. Finally, we discuss frontiers for linking social, ecological, and physical science to advance natural and nature-based solutions to coastal protection.

“…Submerged aquatic vegetation (SAV), including salt marshes, seagrass beds, and kelp forests, provides a wide range of ecosystem services. SAV can attenuate wave energy, mitigate coastal erosion, reduce storm damage, and create habitats for fish and shellfish (Arkema et al, ; Dalrymple et al, ; Guannel et al, ; K. Hu et al, ; J. Hu et al, ; Z. Hu et al, ; Kobayashi et al, ; Lowe et al, ; Maza et al, ; Mendez & Losada, ; Nepf, ; Ondiviela et al, ; Suzuki et al, ). The storm attenuation capacity of SAV needs to be quantified to develop effective and resilient coastal protection, management, and adaptation strategies.…”

Mechanisms for the Asymmetric Motion of Submerged Aquatic Vegetation in Waves: A Consistent‐Mass Cable Model

et al. 2020

Submerged aquatic vegetation (SAV) provides primary products for the food web, as well as shelter and nursery for many juvenile species. SAV can also attenuate waves, stabilize the seabed, and improve water quality. These environmental services are influenced by the dynamic motion of SAV. In this paper, a consistent‐mass cable model was developed to investigate flow interaction with a flexible vegetation blade. Compared with previous vegetation models, the cable model showed improvements in simulating blade motions in waves with and without currents, especially for “second‐normal‐mode‐like” blade motion. Wave asymmetry would cause blade motion to be asymmetric. However, asymmetric blade motion may also occur in symmetric waves. Results indicate that the asymmetric blade motion in symmetric waves is induced by two major mechanisms: (i) the spatial asymmetry of the encountered wave orbital velocities (wave motion relative to blade) due to blade displacements and (ii) the asymmetric action on the blade by vertical wave orbital velocities. Consequently, the blade motion is asymmetric even underneath symmetric waves unless (i) blade length ( l) is much smaller than the wavelength ( lfalse/L≪1), (ii) blade length is much smaller than the water depth ( lfalse/h≪1) in finite water depth waves, or (iii) water depth is much smaller than the wavelength ( hfalse/L≪1). Peak asymmetric blade motion occurs as lfalse/L increases to a critical value. The peak asymmetry increases with wave height and blade length but decreases with increasing blade flexural rigidity. Blade motion characteristics play an important role in wave‐vegetation interaction, wave‐driven currents, wave‐attenuation capacity, breakage of vegetation and ecosystem services.
