“…To correct for the intermediate‐depth problem, approaches worth investigating might be the use of higher‐order Boussinesq formulations (e.g., Liu et al., 2020) or a fully dispersive linear model and provide boundary conditions for FUNWAVE‐TVD to describe the nonlinear shoaling and sediment transport processes. The former would require a higher numerical integration effort, but perhaps could be switched to a lower order dispersion approximation in shallow water.…”

The boat traffic associated with the accelerating urbanization of coastal areas has a significant impact on the health of coastal ecosystems. In otherwise typically quiescent intracoastal and estuarine waterways, the transient wave activity created by boat traffic generates intermittent bursts of higher flow velocities, accelerations, and stresses on the bed, vegetation, and both bivalve and coral reefs. Although boat wakes may have relatively small heights in deep water, they grow, steepen, and break as they shoal on sloping banks/beaches

“…FUNWAVE-TVD has substantial benefits due to the small number of terms in both continuity and momentum equations and precisely simulates the propagation of fully dispersive water waves and the efficiency NBS (e.g., vegetations). However, waves are generally produced and start their journey in deep waters while the depth limitation of the FUNWAVE-TVD models still cannot cover properly the entire domain from shore to the deep ocean when dealing with real life sea states ( Liu et al, 2020 ).…”

Nature-based solutions (NBS) for hydro-meteorological risks (HMRs) reduction and management are becoming increasingly popular, but challenges such as the lack of well-recognised standard methodologies to evaluate their performance and upscale their implementation remain. We systematically evaluate the current state-of-the art on the models and tools that are utilised for the optimum allocation, design and efficiency evaluation of NBS for five HMRs (flooding, droughts, heatwaves, landslides, and storm surges and coastal erosion). We found that methods to assess the complex issue of NBS efficiency and cost-benefits analysis are still in the development stage and they have only been implemented through the methodologies developed for other purposes such as fluid dynamics models in micro and catchment scale contexts. Of the reviewed numerical models and tools MIKE-SHE, SWMM (for floods), ParFlow-TREES, ACRU, SIMGRO (for droughts), WRF, ENVI-met (for heatwaves), FUNWAVE-TVD, BROOK90 (for landslides), TELEMAC and ADCIRC (for storm surges) are more flexible to evaluate the performance and effectiveness of specific NBS such as wetlands, ponds, trees, parks, grass, green roof/walls, tree roots, vegetations, coral reefs, mangroves, sea grasses, oyster reefs, sea salt marshes, sandy beaches and dunes. We conclude that the models and tools that are capable of assessing the multiple benefits, particularly the performance and cost-effectiveness of NBS for HMR reduction and management are not readily available. Thus, our synthesis of modelling methods can facilitate their selection that can maximise opportunities and refute the current political hesitation of NBS deployment compared with grey solutions for HMR management but also for the provision of a wide range of social and economic co-benefits. However, there is still a need for bespoke modelling tools that can holistically assess the various components of NBS from an HMR reduction and management perspective. Such tools can facilitate impact assessment modelling under different NBS scenarios to build a solid evidence base for upscaling and replicating the implementation of NBS.

“…To carry out a high-order Total Variation Diminishing (TVD) scheme easily, the control equations are reorganized as in Ma et al (2012) and Liu et al (2020). To parallelize the numerical model, the Message Passing Interface (MPI) technique with non-blocking communication is introduced into the model as well.…”
