Vertical Accretion and Profile Changes in Abandoned Man-Made Tidal Marshes in the Dollard Estuary, the Netherlands

In the Wadden Sea, an increasing area of the man-made tidal marshes, which cover over 17,000 ha, are becoming nature reserves or parts of national parks. Consequently, management aims altered from reclaiming land towards restoring natural-like marshes. Within this scope, maintenance of the drainage system was discontinued in a 460-ha nature reserve in man-made tidal marshes in the Ems Dollard Estuary, the Netherlands. We collected elevation data in four sections of the nature reserve to study vertical accretion rates and to evaluate marsh-profile changes. Elevations were surveyed in 1984 and i... Mehr ...
