WP2 – Overall description

Work package 2 targets mechanistic understanding and quantification of interactive land subsidence processes and environmental impacts, as occurring under present day human land management (drainage and loading) of soft soils (given historic preconditions).

Subsidence in soft clay-like soils and peat soils is considered the result of processes shrinkage, primary consolidation, viscous behaviour (creep), the loss of fibre strength, and microbial respiration of organic matter. Environmental impacts include subsidence associated greenhouse gas (GHG) emission caused by oxidation of organic matter under aerobic and anaerobic conditions.WP2 wants to resolve the interactive effects and relative contribution of these processes in total subsidence and GHG emissions and build a constitutive model that can analyse and predict soft soil behaviour for the full range of soft soils existing in the Netherlands.
