A fair part of the surface of the Netherlands consists of peat grounds. A large part of these grounds is used for livestock farming. However, the peat needs to be dried to prevent cows and other cattle from sinking with their hooves into the soft, wet peat. This drying starts a process called oxidation. This reaction with oxygen in the air and...

Food forests are gaining attention in the Netherlands as a concept that holds the promise of delivering a variety of ecosystem services our society depends upon. However, there are no insights available what a food forest could look like on peat soils nor what its environmental benefits could be. At the same time the Dutch peat area represents...

Subsidence can be observed at various locations in the Netherlands. While it can be due to both shallow and deep subsurface processes, the shallow subsidence is mainly a result from compaction, oxidation and/or groundwater drainage. Moreover, for grasslands on organic soils, in particular pastures on drained peat soils, the vertical position of...

Recent research effort carried out at Delft University of Technology to improve the experimental knowledge and develop a comprehensive modelling approach for fibrous organic soils is summarised. Experimental results and numerical analyses are combined to discuss some contradictory results which have delayed advanced characterisation of peats....

Delta cities all around the world are under pressure from different forms of climate change effects. Soil subsidence as a result of peat oxidation, and anthropogenic loading of the soil. The soil in many of the heavily urbanised deltas around the world is subsiding faster than the see level is rising as a result of climate change. Few people are...

This paper discusses the results of an experimental programme designed to investigate the deviatoric behaviour of peats. The results are obtained from triaxial experiments carried out on reconstituted peat samples. The interpretation of the experimental results follows a hierarchical approach in an attempt to derive the ingredients that an...

Wetlands are the most important ecosystems on Earth, which can be found in many parts of the world. However, demand for food and economic development in the last century had driven many wetlands in the world being completely drained for cultivation and to the extent that no longer retain any natural wetland characteristics such as the Everglades...

Dicker, Sjors (author)
Peat is formed by biochemical processes and the accumulation of the soil depends on the aerobic and anaerobic conditions. The soil covers five to eight percent of the land surface of the earth. For this thesis a peat coming from a site called Markermeeer, which is a lake between the provinces Noord-Holland and Flevoland in the Netherlands, is...

The geotechnical description of peats represents one of the main challenges in the Netherlands to assure the required safety standard and performance of the flood defence infrastructure. Almost a third of the country is situated below the sea and the rivers level with about 60% to 70% of the population and economic assets concentrated in low...

Chatzis, Konstantinos (author)
The term peat is commonly used to describe organic soils, composed of fragmented plant remains and fibers. Despite the extensive research on the behaviour of peat during the last 50 years, the vast majority of the attention was devoted to the volumetric behaviour. Only few attempts are reported to model the deviatoric behavior of peat, which is...

Fluvial systems in which peat formation occurs are typified by autogenic processes such as river meandering, crevasse splaying and channel avulsion. Nevertheless, autogenic processes cannot satisfactorily explain the repetitive nature and lateral continuity of many coal seams (compacted peats). The fluvial lower Palaeocene Tullock Member of...

Organic soft soils pose technical challenges in construction industry due to their extraordinary compressibility and deformability, which is an issue of particular relevance in the densely populated Netherlands, of which more than half of the land surface is covered by such soft soils. Uncertainty and variability in settlement predictions for...

This study being part of the Weesp Bloemendalerpolder Project, is concentrated on the compression of a peat layer under the weight of a trial sand embankment; examined under two scopes, the laboratory K0-CRS test and the field settlements. Their interconnection is also evaluated. Peat being an organic material with many distinctive...

Zwanenburg, C. (author)
Stability assessment of existing dikes build on soft soil generates questions on the available stability calculation techniques and material models. Especially peat behaviour is not easily captured by standard design methods. This has led to disapproval, based on calculations, of dikes that have been in operation for several hundreds of years....

More than the half of the Netherlands is under the high level of sea and rivers. Therefore, evaluating the safety of dykes is primordial. A specific interest is given to peat dykes safety which suffer of a lack of knowledge which manifested recently by some peat dykes failures (Van Baars 2005). The behaviour of peat is also of interest in others...

About 30% of the increased greenhouse gas (GHG) emissions of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) are related to land use changes and agricultural activities. In order to select effective measures, knowledge is required about GHG emissions from these ecosystems and how these emissions are influenced by management and...

This research investigates the Wilnis dike failure that occurred in the dry summer of 2003. It is believed that drought played an important role in decreasing the stability of the dike, finally leading to failure. In the reported MSc project the situation during drought is simulated with the help of finite element method programs Plaxis and...

Peat is sediment consisting of incompletely decomposed organic matter deposited in swamp and marsh. It has served for a long time as benefits for human beings. Meanwhile, it has posed huge challenges to geotechnical engineers because of its unique characteristics such as anisotropy, low stiffness, high compressibility and strong creep...

Peat soil is encountered in many areas and generally originates from plant/animal remains and is considered partly as decomposed biomass. Due to this composition, the structure of this soil is very different when compared with inorganic soils like clay, sand and gravel. Peat has a high compressibility, low shear strength, high moisture content...
