Abstract Coastal vegetation can reduce extreme water levels during storm events, but the controlling factors and processes in complex estuary or delta systems are still unclear. This limits an effective implementation of nature-based coastal defences mega-cities low-lying areas. Here we have numerically modelled how mangroves offer protection to large cities located Pearl River Delta (China), such as Guangzhou Shenzhen, strong typhoons, like Hato (2017). Water level attenuation by is...
Abstract. The processes of transport, diffusion and transformation surface oil in seawater can be simulated using a Lagrangian model formalism coupled with Eulerian circulation models. This paper describes the conceptual assumptions marine slick numerical rewrites constitutive equations modern mathematical framework. representation requires three different state variables: slick, particle structural variables. Transformation (evaporation, spreading, dispersion coastal adhesion) act on...
Abstract. In this paper we use MEDSLIK-II, a Lagrangian marine surface oil spill model described in Part 1 (De Dominicis et al., 2013), to simulate slick transport and transformation processes for realistic oceanic cases, where satellite or drifting buoys data are available verification. The is coupled with operational oceanographic currents, atmospheric analyses winds remote sensing initialization. sensitivity of the simulations several parameterizations analyzed results validated using...
Nature-based coastal protection is increasingly recognised as a potentially sustainable and cost-effective solution to reduce flood risk. It uses ecosystems such mangrove forests create resilient designs for protection. However, use mangroves effectively nature-based measure risk reduction, we must understand the biophysical processes that govern reduction capacity through ecosystem size structure. In this perspective, evaluate current state of knowledge on local physical drivers ecological...
The tidal stream energy sector is now at the stage of deploying world's first pre-commercial arrays multiple turbines. It time to study environmental effects much larger full-size arrays, scale and site them appropriately. A theoretical array turbines was designed for Pentland Firth (UK), a strait between Scotland Orkney Islands, which has very fast currents. practical power resource large spanning estimated be 1.64 GW on average. ocean response this amount extraction simulated by an...
Abstract The Pearl River Delta contains the world's largest urban area in both size and population. It is a low‐lying flood‐prone coastal environment exposed to sea level rise (SLR) extreme water levels caused by typhoons. A Finite Volume Community Ocean Model implementation for South China Sea used understand how future SLR, tides, typhoon storm surges will interact affect inundation. SLR signal surge provide major contributions flooding; however, amplification of tides could exceed 0.5 m...
Abstract While many studies focus on the persistence of coastal wetlands under climate change, similar predictions are lacking for new wetland establishment, despite being critical to restoration. Recent experiments revealed that marsh seedling establishment is driven by a balance between physical disturbance bed‐level dynamics and root stability. Using machine learning, we quantitatively translate such finding in biogeomorphic model assess extent. This was validated against multiyear...
Thousands of artificial ('human-made') structures are present in the marine environment, many at or approaching end-of-life and requiring urgent decisions regarding their decommissioning. No consensus has been reached on which decommissioning option(s) result optimal environmental societal outcomes, part, owing to a paucity evidence from real-world case studies. To address this significant challenge, we asked worldwide panel scientists provide expert opinion. They were identify characterise...
Abstract. The pan-European capacity for the Ocean Monitoring and Forecasting (MyOcean) Marine Core Service, implementing Global Environment Security (GMES) objectives, targets provision of ocean state observations from various platforms analysis forecasting products to assist, among other downscaling activities, needs operational response marine safety, particularly concerning oil spills. MEDSLIK spill trajectory prediction system makes use MyOcean regional Cyprus Coastal Observing System...
Ocean transport and dispersion processes are at the present time simulated using Lagrangian stochastic models coupled with Eulerian circulation that supplying analyses forecasts of ocean currents unprecedented space resolution. Using approach, each particle displacement is described by an average motion a fluctuating part. The first one represents advection associated current field while second describes sub-grid scale diffusion. focus this study to quantify diffusion written in terms...
Abstract Understanding spatial physical habitat selection driven by competition and/or predator–prey interactions of mobile marine species is a fundamental goal ecology. However, counts or density data for highly animals often (1) include excess zeros, (2) have correlation, and (3) nonlinear relationships with variables, which results in the need complex joint models. In this paper, we test use Bayesian hierarchical hurdle zero‐inflated models integrated nested Laplace approximation (INLA),...
During the Costa Concordia emergency case, regional, subregional, and relocatable ocean models have been used together with oil spill model, MEDSLIK-II, to provide currents forecasts, possible scenarios, drifters trajectories simulations. The results evaluation of their performances are presented in this paper. In particular, we focused work on implementation Interactive Relocatable Nested Ocean Model (IRENOM), based Harvard Prediction System (HOPS), for its validation using released area...
Abstract The environmental implications of tidal stream energy extraction need to be evaluated against the potential climate change impacts on marine environment. Here we study how hypothetical very large arrays and a business as usual future scenario can hydrodynamics seasonally stratified shelf sea. Scottish Shelf Model, an unstructured grid three‐dimensional ocean model, has been used reproduce present state NW European continental shelf. Four scenarios have modeled: conditions projected...
Switching from fossil fuels to renewable energy is key international transition efforts and the move toward net zero. For many nations, this requires decommissioning of hundreds oil gas infrastructure in marine environment. Current international, regional national legislation largely dictates that structures must be completely removed at end-of-life although, increasingly, alternative options are being promoted implemented. Yet, a paucity real-world case studies describing impacts on...
