Purpose: The microbial turnover of sediment organic matter (OM) in ports and waterways impacts water quality, sonic depth finding and presumably also rheological properties as well as greenhouse gas emissions, especially if organic carbon is released as methane. As a consequence, sediment management practices as a whole are affected. This...

Effective gas permeability is an important parameter in the design of methane oxidation systems, governing diffusive oxygen ingress and the spatial spread of landfill gas. The influences of soil texture, compaction, soil moisture and the resulting air filled porosity on the gas permeability were researched by performing pressure loss...

Purpose: Climate change necessitates heightening and strengthening of dikes, requiring large volumes of suitable soil. This study investigated soil ripening and long-term development of hydraulic behaviour of a dike constructed from slightly contaminated, partially dewatered dredged material from the Port of Hamburg under realistic conditions...

A prerequisite for the application of stable isotope fractionation for the quantification of the methane (CH4) oxidation efficiency of landfill covers is that the fractionation factor αox is known or can be estimated with adequate accuracy. So far, αox has only been determined in laboratory experiments. In this study, αox was determined under in...

The cover system of the mono-landfill Hamburg-Francop for disposal of dredged<br/>material comprises a mineral liner of pre-treated fine-grained dredged material (‘METHAmaterial’) and an overlying drainage layer of pre-treated sandy dredged material (‘METHAsand’). Water balance and effectiveness of the cover with respect to minimising...
