Abstract Sandy shorelines morphodynamics responds to a myriad of processes interacting at different spatial and temporal scales, making shoreline predictions challenging. Shoreline modeling inherits uncertainties from the primary driver boundary conditions (e.g., sea‐level rise wave forcing) as well related model assumptions and/or misspecifications physics. This study presents an analysis associated with future evolution cross‐shore transport dominated sandy beach Truc Vert (France) over...
Long-term (>decades) coastal recession due to sea-level rise (SLR) has been estimated using the Bruun Rule for nearly six decades. Equilibrium-based shoreline models have shown skillfully predict short-term wave-driven change on time scales of hours Both and equilibrium rely beach theory, which states that profile shape equilibrates with its local wave conditions. Integrating these two into a unified framework can improve our understanding predictive skill future behavior. However, given...
Abstract Shoreline change is driven by various complex processes interacting at a large range of temporal and spatial scales, making shoreline reconstructions predictions challenging uncertain. Despite recent progress in addressing uncertainties related to the physics sea‐level rise, very little effort made towards understanding reducing wave‐driven response. To fill this gap, associated with long‐term modelling are analysed high‐energy cross‐shore transport dominated site. Using...
Sandy beaches are highly vulnerable to short-term and long-term erosion due waves sea-level rise (SLR), respectively. As global SLR is accelerating climate change, reliable projections of shoreline change on long time scales (greater than decadal) critical for coastal adaptation planning. Some models that address such long- term rely the equilibrium beach theory estimate effects SLR. However, so far, interactions between wave action not resolved explicitly. In this work, we present a novel...

With climate change and accelerating sea-level rise (SLR), long-term predictions of shoreline evolution are crucial to assess adaptation plans in coastal areas. Meanwhile, knowledge gaps the physics response combined action waves SLR hinder making reliable projections. Equilibrium beach theory states that a profile shape equilibrates with its local wave conditions. In context equilibrium theory, we present physical interpretation leads identification two main contributing processes: passive...
Based on the maximum wave momentum flux approach (MFA) originally proposed by Hughes, simple predictive equations for reflection coefficient of sloping coastal structures have been developed. The design tools permit either estimating "bulk" or reconstructing entire reflected spectrum. A comparison with nearly 1,600 results physical model studies carried out in different laboratories around world indicated new method to be rather effective, especially case permeable structures.

Chronic erosion of sandy coasts is a continuous potential threat for the growing coastal communities worldwide. The prediction shoreline evolution therefore key issue robust decision making worldwide, especially in context climate change. Shorelines respond to various complex processes interacting at several temporal and spatial scales, reconstructions predictions challenging uncertain, on long time scales (e.g. decades or century). Despite increasing progresses addressing uncertainties...
Many flat coastal plains are already subject to recurrent high-tide flooding events under calm meteorological conditions. As a consequence of sea level rise (SLR), the frequency such harmful is expected increase. Although not catastrophic, may become major adaptation challenge as they could cause substantial transportation and economic disruption. In many low-lying zones in world, an increasing occurrence has indeed been recorded. This often accompanied by land subsidence. The French Guiana...
<p>Most sandy coasts worldwide are under chronic erosion, which increasingly put at risk coastal communities. In the context of adaptation to climate change and sea-level rise (SLR), predictions shoreline evolution patterns critical for decision-making. Sandy shorelines highly dynamic environments, respond multiple complex processes interacting different spatial temporal scales, making challenging, especially on long time scales (decades centuries). However, modelling inherit...
