Determining drought-induced subsidence in urban areas: An in-practice analysis of drought impacts on subsidence in two Dutch soft-soil cities

Drought and subsidence are two out of several water-related urban climate adaptation challenges many cities in the Netherlands currently face. Drought is expected to increase in frequency and extent due to climate change. Therefore, drought is likely to further pressurize (subsiding) urban areas in the coming decades. Although the impact of...

Numerical assessment of preloading strategies for jack-up vessels in cohesive soils

As the demand for renewable energy is constantly rising, more offshore wind farms are being built at sea to meet European targets towards sustainable energy transition. Van Oord’s offshore installation vessel Aeolus was purposely-built to transport and install foundations of offshore wind turbines. To ensure that the vessel remains competitive...

Structural consolidation of historic monuments by interlocking cast glass components: A computational analysis of interlocking cast glass brickwork

The search for a transparent, reversible, and reusable consolidation system for monuments led to the ambition to test possible cast glass interlocking brick designs using numerical calculations. The focus of this research is hence the design, simulation and evaluation of a possible cast glass interlocking geometry using Finite Element Analysis ...

Desiccation, Crust Formation & Consolidation of Soft, Cohesive Soil due to Atmospheric Conditions: A case study of the Marker Wadden

Deterioration of the ecological quality within the Markermeer, due to the elimination of natural flushing and a resulting increase in turbidity, has created a need to revitalize the region for the benefit of the local wildlife. One major way in which this is being achieved is through the Marker Wadden, designed as a wetland area featuring a...

The effect of initial concentration on the consolidation behaviour of mud: A study on lake Markermeer sediment

Land reclamations in deltaric areas provide space to meet the demand for a safe place to live and work. Sand, a traditional filling material in some locations is becoming scarcer. An alternative filling material is mud. Mud consists of clay, silt, sand, organic material, water and gas. Therefore, it is a versatile material and difficult to...

Review and validation of settlement prediction methods for organic soft soils, on the basis of three case studies from the Netherlands

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...

Consolidation be haviour of soft cohesive soils, the correlation between different scale model tests: Case study of the Marker Wadden

A group of islands will be constructed in the lake Markermeer to act as nature reserve for birds, called the Marker Wadden. These islands will be constructed out of soft clay, dredged from the bottom of the lake. Building with soft cohesive soils, also referred to as mud, is still a largely unknown territory. Traditionally, sand is used for land...

The created value of an Urban Consolidation Centre differentiated in last-mile and network-associated value

The last few miles when transporting goods are often the most expensive. This is called the `Lastmile' and is under increasing attention in literature and with decision makers. In addition to being expensive the last mile frequently runs through urban areas and contributes to local pollution and congestion. One possible method to increase...

Physical and numerical modelling of the erosion of a fluid mud layer due to entrainment

The subject of this master thesis is to present the processes taking place at the erosion of a fluid mud layer due to entrainment, to carry out experiments in an annular flume and compare the results of these experiments with a numerical model, which has been elaborated at the TU Delft. The report can be devided into five parts: physical and...

Self-weight consolidation on impervious bases

This paper presents the study on the self-weight consolidation, which is referred to the consolidation problem of cohesive deposits in reservoirs and based on Gibson's theory of non-linear finite-strain consolidation. The analytical solution of the linearized equation is carried out. The solution shows that the consolidation is dominated by the...
