Products of knowledge

Understanding silt dynamics using silt modelling
Insight into silt dynamics using silt modelling

What is it?
Calculation model that describes flooding and silt economics in the Markermeer.

What can we use this for?
The programme provides insight into the way in which silt erosion and sedimentation are influenced by wind direction and wind speed. This understanding is used to test the influence of interventions in the Markermeer (such as construction pits, dams, banks, etc) on the clarity of the water.

Who will be interested?
Managers of water systems, in this case RWS IJsselmeergebied, as well as organisations involved with planning the redevelopment of the Markermeer.

Guideline for development of wetlands

Careful preparation makes half the work

What is it?
A guideline to speed up decision-making in relation to area development in a wetland, for example in the Markermeer.

What can we use this for?
The guideline formulates three elements: (1) An agreement which unites all the social organisations
involved, enabling development of the plan to be dealt with jointly.
(2) A steering committee that supervises the processes and is supported by a social knowledge cluster.
(3) The knowledge cluster makes available know-how, insight, and a perspective on required action for the processes involved in the area.

Who will be interested?
All (social) organisations involved in the development of an area such as the Markermeer.

Consequences of intervening in wetlands channel bed
Environmental impact rapidly calculated

What is it?
A new calculation model that combines a transport model and a (geo) chemical model.

What can we use this for?
Managers can use this model to predict and evaluate the possible damaging consequences of interventions and the effectiveness of management measures, in both the short- and the long-term. The new model is validated using a large measurement programme, where the interface between a contaminated channel bed and the water is tested and analysed.

Who will be interested?
Department of Transport, Public Works, and Water Management, consultancies, water managers, dredging companies.

Impact of water level dynamics on the ecological quality of water bodies
Aquatic ecosystem climate-durable

What is it?
Based on existing ecological knowledge of the IJsselmeer area, HABITAT has been used to survey the effects of increasing water level dynamics on the ecological quality of the IJsselmeer area.

What can we use this for?
Climate change will lead to major changes in water management in order to guarantee safety and the provision of fresh water. This also has consequences for the development of aquatic eoosystems. Solutions will be sought for the climate-durable development of aquatic ecosystems.

Who will be interested?
Consultancies, water managers, policy makers.

Markermeer cost-benefit analysis

Feasibility by means of creativity

What is it?
A cost-benefit analysis was drawn up for the possible re-development of the Markermeer.

What can we use this for?
The result shows that possibilities exist to combine nature development, recreation, residential housing and infrastructure in an economically viable way.

Who will be interested?
Organisations involved in the re-development of a wetland.

Building with Nature
Putting nature to work

What is it?
‘Building with Nature’ is an innovation programme focusing on the development of knowledge, expertise and solutions for the sustainable development of coastal, delta, and river areas, based on the dynamics of the ecosystem and using the forces present in nature. And without disregarding the infrastructural and economic pre-conditions. Areas of expertise such as ecology, technology- and policy sciences are brought together in pilot studies for the development of the south-western Delta, the Dutch coast, the IJsselmeer, and the coastal area of Singapore. The results will be incorporated in a manual that will be aimed at practical use.

What can we use this for?
To combine the development of hydraulic engineering infrastructure with new opportunities for nature by using nature’s own forces.

Who will be interested?
Those involved with hydraulic engineering in The Netherlands, engineering consultants, policy makers, managers, knowledge institutes

Course  ‘Sustainable development of water-rich areas’
Fulfilling planning ambitions in a natural environment

What is it?
4-day PAO/Deltares course.

What can we use this for?
Course participants:
• Learn about the requirements of Natura 2000 and the Dutch nature protection policy in wetlands, to integrate them in the design, implementation and management of infrastructure, such as a yachting harbour, residential area, or dike strengthening.
• Gain knowledge about the ecological, hydrological and morphological processes of wetlands.
• Using the natural system as the starting point, learn what the environmental impact is of civil engineering interventions and which solutions are available.
• Are made aware of decision-making processes and learn to take the different interest of stakeholders into account. 

Who will be interested?
Engineers, project leaders and managers of wetlands: water boards, Department of Public Works, provinces, consultancies who are responsible for interventions in water-rich areas and who must deal with the consequences of Natura 200 and other nature protection regulations.
