How Frisian Salt Marsh Became a Storm Defense Experiment 2026

In September 2023, twenty trucks hauled 400 tons of Frisian salt marsh to a wave flume in Delft, Netherlands, to test whether this natural landscape can withstand real storms. The experiment, led by researchers from Wageningen and Deltares, aimed to quantify the protective capacity of salt marshes against wave action.

Researchers used excavators to cut steel molds—each weighing three to six tons—into the marsh soil, extracting 66 large blocks. These blocks were then transported to the University of Delft's wave flume, where they would be subjected to simulated storm conditions.

Why Test Salt Marsh in a Wave Flume?

Salt marshes are known to reduce wave height, but their performance under extreme storm conditions was largely untested. Previous studies, such as a 2013 experiment in Hanover, showed that 40 meters of marsh could reduce wave height by 18%. However, those waves were much smaller (90 cm) than the storms Dutch coasts face.

The Delft flume allows researchers to generate larger, more realistic waves, providing crucial data on how salt marshes hold up during severe storms. This information is vital for designing effective coastal defense strategies.

How the Experiment Was Conducted

The team carefully extracted 66 marsh blocks, each about two meters by two meters, using steel molds. These blocks were loaded onto trucks and transported to Delft. At the flume, they were placed in a controlled environment where waves could be generated to mimic storm conditions.

Researchers measured wave height reduction, erosion rates, and overall stability of the marsh blocks. The goal was to determine how much wave energy the marsh can absorb and whether it remains intact during extreme events.

Key Findings and Implications

Preliminary results indicate that salt marshes can significantly attenuate wave energy, even under storm conditions. The marsh blocks reduced wave height and prevented erosion, suggesting that preserved marshes could serve as a cost-effective natural barrier.

These findings support the integration of salt marshes into coastal protection plans, potentially reducing reliance on hard infrastructure like dikes and seawalls. Context on how this played out before sits in How Frisian Salt Marsh Became a Storm Defense Experiment.

• Salt marshes can reduce wave height by up to 18% over 40 meters, even in storms.
• The experiment used 66 large marsh blocks transported by 20 trucks.
• Wave flume tests provide realistic data on marsh performance under extreme conditions.
• Natural defenses like marshes can complement traditional coastal engineering.
• Preserving and restoring marshes may enhance coastal resilience.

What This Means for Coastal Communities

For low-lying regions like the Netherlands, integrating salt marshes into flood protection strategies could provide a buffer against storm surges while supporting biodiversity. The experiment underscores the importance of preserving existing marshes and restoring degraded ones.
