Saltmarshes in most estuaries in the UK and elsewhere are heavily exploited for numerous purposes including farming, fishing, and recreation. In this study, a computational model was used to investigate the impact of saltmarsh vegetation on tidal dynamics and residual currents in three distinctly different estuaries in Wales, UK, in order to unders...

The paper investigates compound flooding from waves, sea surge and river flow in northern Jakarta, Indonesia, which is a global hotspot of flooding, by combining process-based coastal and river models. The coastal hydrodynamic modelling of Jakarta Bay in Indonesia shows that coastal storms can lead to a substantial increase in sea water level due t...

Habitat suitability modelling (HSM) is a tool that is increasingly being used to help guide decision making for conservation management. It can also be used to focus efforts of restoration in our oceans. To improve on model performance, the best available environmental data along with species distribution data are needed. Marine habitats tend to ha...

Full-text available
As storm-driven coastal flooding increases under climate change, wetlands such as saltmarshes are held as a nature-based solution. Yet evidence supporting wetlands’ storm protection role in estuaries - where both waves and upstream surge drive coastal flooding - remains scarce. Here we address this gap using numerical hydrodynamic models within eig...

Article
Full-text available
The ability of coastal vegetation to attenuate waves has been well established (Moller et al., 2014). Salt marshes are vegetated coastal wetlands that can act as nature- based coastal defenses. They exhibit a range of plant species, which have been shown to differ in the amount of wave damping they provide (Mullarney & Henderson, 2018). Recent stud...
Article
Full-text available
Saltmarshes are considered as natural coastal defences. However, owing to the large context dependency, there is much discussion over their effectiveness in providing coastal protection and the necessity of additional coastal defence interventions. The macro-tidal Taf Estuary in south-west Wales was chosen as the case study in this paper to investi...
Article
Full-text available
Purpose Coastal flooding has disastrous consequences on people, infrastructure, properties and the environment. Increasing flood risk as a result of global climate change is a significant concern both within the UK and globally. To counter any potential increase in future flooding, a range of potential management options are being considered. This...
Conference Paper
Full-text available
The use of saltmarshes as an intervention to alleviate the effects of coastal flooding has gained increasing intention due to climate change. A coupled Delft3D FLOW-WAVE model was developed for the macrotidal Taf estuary in South West Wales to assess how three different interventions on saltmarsh management affected coastal flooding. An extreme sto...
Conference Paper
Full-text available
Salt marshes are coastal wetlands that can reduce flood risk by their vegetation. The drag that salt marsh plants induces on currents modifies estuary hydrodynamics which affects flood water levels, surge propagation and sediment transport. Four parameterisations to model the drag by vegetation on currents have been proposed in literature: (i) a fi...
Article
Full-text available
Global climate variabilities have the potential to impact many coastlines around the world, and can have detrimental effects on the stability of coastlines and their function as natural coastal defenses. This paper investigates the impacts of future extreme storms and sea level rise on morphodynamics of the macro-tidal Sefton Coast, UK, taking a pr...
Conference Paper
Full-text available
Salt marshes are vegetated tidal wetlands, which can typically be found at sheltered coastal areas in moderate climate zones. Their potential as natural coastal protection by wave attenuation (Möller et al, 2014), reduction of flood-surge propagation (Stark et al., 2016) and shoreline stabilization (Bouma et al, 2014) has been increasingly recogniz...
Conference Paper
Full-text available
A set of storms, with varying intensity and duration, was used to investigate the range of morphological impacts on a macro-tidal beach (Sefton coast, Liverpool Bay, UK), using a nested computational modelling framework. Extreme wave and water level conditions were extracted from modelled and observed data corresponding to a range of return periods...
Article
Full-text available
Understanding the changes in future storm wave climate is crucial for coastal managers and planners to make informed decisions required for sustainable coastal management and for the renewable energy industry. To investigate potential future changes to storm climate around the UK, global wave model outputs of two time slice experiments were analyse...
