TIDE pilot 1: large scale execution “plaatrandstortingen” (2010), relocation of dredged sediment to shallow water areas near sandbars

Degree of synergistic effects and conflicts according to WFD aims

Important benefits of those measures in the polyhaline zone of the Scheldt estuary are the contribution to the creation of new intertidal wetlands and local change in bathymetry. Finally, it offers a permanent and controlled relocation strategy.

Indicator Group Code Main pressures polyhaline zone Scheldt Effect? Description

S.I. 1.1 Habitat loss and degradation during the last about 100 years: Intertidal       X   Enlargement of the sandbar, creation of low dynamic intertidal and shallow area
S.I. 3.1/3.2 Decrease of water and sediment chemical quality       X   Local change of bathymetry
S.I. 3.3 Increased chemical loads on organisms     X      
D.I. 1.7 Relative Sea Level Rise     X      
D.I. 2.6 Capital dredging     X      
D.I. 2.12 Port developments       X   Alternative relocation strategy after dredging
