Numerical modelling assumptions for deposition and spread of dumped material
Journal Title: Biuletyn Instytutu Morskiego - Year 2015, Vol 2, Issue 1
Abstract
Dredging is a necessary part of harbour operations, associated with the maintenance of the required navigable depths of approach channels and harbour basins. The fine dredged material obtained particularly from harbour basins often cannot be used in a beneficial way and must be disposed of at sea. Dumping dredged material at sea might have an adverse effect on the environment, so in this context one should seek to minimize the negative impacts associated with this type of operation. The potential of numerical models developed using the MIKE 21 package was tested, in order to assess the impact of disposal sites in different phases of their operation on the marine environment. The present paper examines the technical aspects of the construction phase of a numerical model which would be useful to describe the spillage of dredged material from the disposal site, both when the deposit operation takes place as well as in the subsequent period. Comments relate to the selection of a computing area, the model’s time scale, issues associated with determining the boundary conditions on the model’s open boundaries, and the optimal range for conducting computational simulation. The article also high lights the importance of identifying the relevant characteristics of the seabed and the material deposited on the reliability of the numerical model which is created.
