Control of Subsurface Flow: The Effect of Al-OM Interactions on Hydraulic Conductivity

Control of subsurface flow is important for sustainable water management. It is, for example, a useful tool for the handling of contaminated sites or the reduction of unwanted seepage. In this thesis the complexation interactions between DOM and Al are successfully used to reduce the hydraulic conductivity of a sand layer. The complexation of Al...

Reconstitution of sensitive clays

In this thesis a method is developed to regain the geotechnical behaviour of undisturbed quick clay by reconstitution of remoulded natural quick clay samples. Quick clay is characterised by a high sensitivity; the ratio between the undisturbed and remoulded strength is very high. Because of the high water content they behave fluid-like after...

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...
