Spotlight on salt marsh construction January 20, 2021, by Eldin Ganic Salt marshes were created on the coast of Delfzijl in the north of the Netherlands in 2018. A section has been used as a trial location for salt marsh development. Researchers from EcoShape studied the salt marsh for two years to learn more about the construction and development of salt marshes. The results of this trial can be used worldwide on sediment-rich coasts to enhance coastal protection and biodiversity. The research focused on the change in the height of the marsh surface due to sediment accretion, wave attenuation and the development of biodiversity on the salt marsh. The findings are positive.
