Summary: The long-term sediment demand of the Dutch coast is important for the current Dutch Coastal Flood and Erosion Risk Management policy. The Coastal Genesis 2 research programme was initiated to address the sustainability of this policy under sea level rise by focusing on key uncertainties in the conceptual model of the sediment demand. The analysis of this programme's scientific contributions highlights the importance of synthesising new insights into shared conceptual models for impact in policy and practice.

Summary: The Dutch coast is one of the largest nourished coastlines globally, with a significant amount of sand added annually to protect it. This study provides an overview of the nourishment operations conducted since the 1990s and discusses the evolution and lessons learned from nourishment design. Through various nourishment methods, the Dutch coast has successfully conserved its coastline.

Summary: In response to climate change and sea-level rise, new nourishment strategies have been developed for low-lying sandy coasts, which can affect the habitat quality of coastal ecosystems. By studying the relationship between benthic fauna and their environment, researchers can design sustainable management strategies for these ecosystems. A unique dataset of benthic and sediment samples collected at the ebb-tidal delta of Ameland, The Netherlands allowed for an investigation into the distribution of macrobenthic fauna and its correlation with morphological features. The findings revealed distinct species assemblages along gradients of physical stress and exposure, which were reflected in the sediment characteristics. Additionally, the functional characteristics of the benthic fauna showed clear contrasts between exposed and sheltered areas, suggesting different recovery rates in response to disturbance.

Summary: The Dutch coastal policy aims to maintain a safe, economically strong and attractive coast through sand nourishments. This study investigates sand transports at different depth contours along the Dutch lower shoreface using a computational approach. The results show that the net annual sand transport rates are influenced by tidal velocities, residual flows, wind and waves. The alongshore transports vary along the 20 m depth contour and the total cross-shore transports increase with decreasing water depth. Density and wind affect the flow structure and sand transports. Storm conditions play a significant role in the magnitude and direction of the net annual transport rates.

Summary: The Wadden Sea, a unique intertidal wetland area, provides an important habitat for migratory water birds. This study examines the impact of sea-level rise on the intertidal flats in the Dutch Wadden Sea. The results show that the larger basins are most vulnerable to drowning, while the smaller basins experience a decrease in average height and surface area. The rate of sea-level rise has a significant influence on the extent of losses. It is predicted that by 2100, the larger basins could lose nearly 50% of their volume under the highest sea-level rise scenario, resulting in major ecological consequences.

Summary: This paper describes the development of the Coastal Genesis 2 research programme and its contribution to Dutch coastal policy. It addresses the organization of policy development related to coastal flood risk and erosion in the Netherlands, focusing on the division of responsibilities between the policy and operational directorates of the Ministry of Infrastructure and Water Management. The paper details the conceptual model of the long term sediment budget of the Dutch coast that supports the current Coastal Flood and Erosion Risk Management policy.

Summary: Detailed observations and analysis of ebb-tidal delta dynamics and interactions with shorelines are crucial for barrier island management. The intra-delta dynamics of Ameland Inlet in the Netherlands have undergone significant changes over 15 years, with sand transport between islands leading to channel relocation.

Summary: This study investigated the composition and distribution of Holocene and late Pleistocene deposits at the surface and in the shallow subsurface of the lower shoreface of the Dutch coast through vibrocores collected in three coastal sections. Six different depositional environments were identified, showing contrasting settings and characteristics in different areas of the Dutch coast. Further investigation is required to understand erosion processes and sediment transport in these areas.

Summary: The sediment exchange between the Dutch Wadden Sea and the North Sea coastal zone is crucial for coastal management and understanding the current and future sediment exchange is essential. Projections show that the differences in sediment import rates between sea level rise scenarios are not as large as expected.

Summary: The lower shoreface is an important transitional zone between the inner shelf and upper shoreface, providing sediment to the upper shoreface and beach. This study investigates near-bed orbital velocities and small-scale bedforms in the Dutch lower shoreface. The results show significant sediment mobility under high wave conditions, with near-bed orbital velocities increasing with wave height and decreasing with water depth. Ripple dimensions are mainly controlled by wave mobility and not so much by currents.

Summary: Understanding the hydro- and morphodynamics of the lower shoreface is crucial for coastal management and maintenance. The Dutch coast's shoreface is influenced by past evolution and present-day processes. The morphology varies along the coast due to coastal slope and superposition of ridges and ebb-tidal deltas. Field data and numerical modeling were used to study the lower shoreface, revealing variations in composition and morphology. Sand transport and sediment changes are important factors in the study. The results show different patterns of sand transport and trends in the shoreface morphology along the coast.

Summary: This study investigates wind-driven fluxes and residual water flow in multiple tidal inlet systems. It shows that water and sediment fluxes occur at the boundaries of these systems during wind events. Numerical simulations indicate that wind-driven fluxes increase conveyance capacity, leading to higher exchange flows.

Summary: Sediment tracer studies track individual sand or silt grains in marine environments, assessing connectivity between sediment sources and sinks. In this study, dual signature sediment tracers were used to simulate the dispersal of dredged sediment on an energetic ebb-tidal delta. The findings and approach from this study provide tools for assessing complex coastal environments and planning for future responses to climate change.
