The project focuses on the birth and prevention of thick mud layers in the canals of the Dutch Water Board's Schieland district. An alternative dredging method will be tested in one of the canals of this area, which focuses on early removal of the young mud layer which is known as Sapropelium. In order to do so, the following activities have already been or will be carried out:
- Inventory and analysis of mud accumulations in the canals of Kralingen and Capelle: A study has been conducted to explain local mud accumulations in the canals of Schieland. These accumulations appear to be situated near culverts. Several reasons for this have been found. In addition, steering parameters are described which may be used to influence local mud accumulations.
- Research on the source and supply of materials that cause mud. For this topic WL / Delft Hydraulics conducted a literature survey on the characteristics of Sapropelium. Additionally, WL / Delft Hydraulics acted as an advisor for the development of a measuring method in order obtain samples of materials that settle over time in the water column. WL / Delft Hydraulics designed the prototype of this measuring tool. The actual measurements will be performed by the Schieland District Water Board.
- Test with the alternative dredging method: The tests will be performed by a local Dutch contractor. WL / Delft Hydraulics acted as an advisor for the design of the alternative dredging method and the actual location of the test site. The tests still need to be carried out. |
