Summary

To implement the current policy, Rijkswaterstaat replenishes an average of 12 million m3 of sand annually. Exactly how much sand is needed and at which places and times the sand can best be deposited is based, among other things, on the annual assessment of the coast and knowledge and experience of the sandy coastal system.

The long-term knowledge program Beheer en Onderhoud van de Nederlandse kust (B&O kust) aims to answer research questions about nourishments and to expand and spread knowledge about the coastal system. Deltares and Rijkswaterstaat work together in this program.

The approach is a cyclical process: Rijkswaterstaat bases choices about nourishments and coastal management on the existing knowledge of the coastal system. If there are knowledge gaps, hypotheses are formulated for this. Testing these hypotheses and answering the research questions that arise in this context are tackled in sub-projects. New insights resulting from the research can lead to adjustments in the implementation of nourishments and coastal management.

In addition to answering research questions and testing hypotheses, the B&O kust program also has the objective of disseminating knowledge and issuing regional advice (aimed at questions from the coastal management of the Rijkswaterstaat regional departments).

B&O Coast Projects

The B&O Coast program consists of four projects in which different aspects of the morphological and ecological system are central. Data analyses and model simulations are carried out per project to answer research questions and to test hypotheses.

1. Condition of the coast
2. Exchange tidal basins & Morphodynamics island heads
3. Operation of coastal foundation & Redistribution nourishment sand
4. Specialist advice

State of F

It seemed at first that most of the data sets in this project were already AIR or even FAIR. When searching for them; and when searching for them, some also appeared to be FAIR already!

State of A

For Deltarians, the accessibility of most data sets was quick, with one or a few clicks. For the data sets that were put on the Deltares Data Portal via a harvester, the "OpenDAP service" link never worked; only the Direct Download link worked.
