Pressures due to Climate Change
accelerating sea level rise stronger
storm intensity higher set-up
greater water depths, stronger wave loads
delayed adjustment
of the tidal flat heights

Sediment Management Statements
• Entry of sediment and local impact
• Need of sediment in coastal waters
• Role of mudflats
• Accelerating sea level rise -> higher demand for sediment
• Further usability of sediment in the area
• Additional sources ?

Sediment Management Fundamental Issues
Need for system-wide approach and sustainable solutions
• Analysis of essential aspects
• Function of sediment with regard to sea level rise
• Already existing needs for sediment
• Separation of sediment fractions useful and possible?
• Ems–Estuary: silt as valuable material
