Dynamics of mega-nourishment

Integrated model approach for the design of Mega-nourishments

Objectives

In September 2008 the committee Veerman presented their report, Working together with
water. The report describes opportunities to change the political policy regarding integral
coastal management. Their recommendations and conclusions on behalf of integral coastal
management involved the applicability of large-scale nourishments to counter balance for sea
level rise and provide coastal protection. The Zandmotor can be seen as a first step for largescale
nourishments to counter balance for sea level rise in combination with space for nature
and recreation, from a societal perspective. Because of its uniqueness in integral coastal
management the Zandmotor is carried out as a pilot project. If the government wants a
project like the Zandmotor to succeed there has to be public support. To achieve this support,
uncertainties in relation to swimming safety, siltation, groundwater, etc. need to be
investigated. Therefore results from this thesis, like for most reports made so far concerning
this project, need to be linked and translated to a societal perspective.

The meaning of this thesis is providing an integrated model approach, in order to improve the
design approach for future large-scale nourishments. Focus of this thesis lies within the
answering of questions, and to narrow or exclude uncertainties that have emerged from
several stakeholders. One of the main goals of the project the Zandmotor is to gather
knowledge of its development. The approach for providing integrated model tools can be
done by coupling between several numerical models. Hereby advantages of several models
can be combined.

Current work

Providing an integrated model for the design of mega-nourishments can be achieved through
coupling several numerical models. Coupling these software packages, characteristic
features of each numerical model can be used. This will enable interaction between multiple
morpho- and hydrodynamic processes. The new integrated models, are expected to provide
new insight of these processes between multiple temporal and spatial scales.
