Component 5 contains all activities regarding the planned best practice guideline “Dredged Materials in Dikes Construction”. The guideline will enable authorities and planners among the South Baltic region to efficiently use different dredged materials in dike construction. It will cover basic knowledge about dredged materials and dike construction, design and construction rules, construction methods and environmental aspects.
…
Background
The development and implementation of a best practice guideline is the main concern of the German authorities AP1 / AP2 (State Agency for Agriculture and Environment StALU / Federal Waterways Engineering and Research Institute BAW) and the Polish authority AP3 (Maritime Office in Gdynia). German and Polish authorities rely on handbooks and guidelines, approved by federal authorities, like AP2, if it comes to the implementation of new materials and solutions. Thus to use the dredged materials on a larger scale and to trigger an extensive positive environmental impact, a knowledge-based best practice guideline is essential.
…
Aim
The aim is to make the dike construction technology transferable to other projects so that it may be implemented all along the Baltic Sea Coast.
…
Contents
The implementation of the guideline will comprise best practice methods for dike construction using dredged materials or soil-ash mixtures considering site-specific conditions. Different cross-sections of dike construction will base on investigated project results from laboratory and field testing as well as the pilot project. References to the existing guideline for assessment of dredged materials and coastal risk management strategies will be made in order to simplify the handling and practice of dredged materials. The guideline will include following chapters:
- State of the art of dike construction at least in the two partner states.
- Experimental work (laboratory and/or field testing) necessary for the implementation of the different dredged materials solutions.
- Construction rules for the application of different systems of ash-improved dredged materials and combinations with geosynthetics will be developed, based on existing design rules and on the results from the field tests performed in Rostock and Gdańsk.
- Environmental aspects and quality control will, based on the experience from both field tests and pilot projects.
…
Multilingualism
For future implementation of the best practice guidelines in authorities and companies all over the South Baltic region, the guideline needs to be multilingual. Therefore it will be initially translated in at least 3 languages, German, Polish, and English. Russian and Swedish may be considered as well.
…
Distribution
The guideline will be distributed both in Germany and Poland as well as beyond the project area within the South Baltic region (see also Component 2). You will find a PDF version on this website as free download.
