Analysis of a new structure for offshore waste landfill &#8211 Contaminant transport characteristics affected by tidal fluctuations

Abstract

The paper deals with water cut-off walls for offshore waste landfill facilities that are used to prevent leakage of toxic substances to the surrounding water. A new type of a widely used water cut-off wall called Steel Pipe Sheet Piles (SPSP) is investigated with experimental measurements as well as numerical simulations. The main objective is to found out the influence of tidal fluctuations in the sea on the outflow of the contaminant and the results show that the outflow of contaminants is lower when tidal fluctuations are present compared to the case with only a mean water level. The influence of different filler materials on this behavior is also investigated.P) is investigated with experimental measurements as well as numerical simulations.
