Dissertation title: 

Wetland eco-engineering with fine sediment

Group: Utrecht University, Environmental Sciences
Promotor: Prof.dr. Martin Wassen


Fine sediment – available in large quantities in many river delta’s – may be used as an alternative to coarse sand for land reclamation. In this study, the Marker Wadden project functioned as a case for optimizing ecological engineering designs that use fine sediment as building material. The research presented in the thesis has highlighted (bio)geochemical, hydrological, and wetland ecological processes that interact and enhance ecosystem development on wetlands built on fine sediment. A combination of greenhouse and laboratory experiments were conducted. Some measured data from these experiments formed important input for subsequent analysis in a modeling environment. The findings presented in the thesis can be divided into four topics: 1) Plant–soil interactions in the terrestrial zone, 2) wetland–terrestrial processes influencing nutrient availability in the land–water zone, 3) effects of plants on sediment consolidation in the terrestrial zone, and 4) effects of bioturbation on nutrient availability in the aquatic zone.
