Influences of ice lens formation in a silty soil

Artificial ground freezing (AGF) has been applied over 150 years for mining, and was adopted for civil engineering purposes more than 30 years ago. AGF is used as a construction method to provide structural support and to exclude groundwater. Due to 9 percent volumetric expansion of pore water during freezing, soil experiences primary heave. In...

Fieldwork Coastal Engineering 2014

This report is the final part of the course CIE5318 Fieldwork Hydraulic Engineering at the TU Delft. In this course a group of international students from the TU Delft a and the Varna Free University visit the coast of the Black Sea. During their weeks visit they do field research in Varna, Bulgaria and visit the harbor of Constanta, Romania....

Assessing robustness and quantifying uncertainty in level set segmentation of the bowel lumen

This thesis explores various methods to assess the robustness of an algorithm used to determine the severeness of Crohn's disease, segmenting the bowel lumen by minimizing a total variation based energy functional similar to the Local Gaussian Distribution Fitting energy functional. By comparing the local solution of this minimization problem...

Impulse Based Substructuring Unravelled; Simulation and Coupling of Structural Dynamics in the Time Domain

One way of deriving the dynamics of a structure, is by combining the dynamics of its substructures. This concept is named ’Dynamic Substructuring’ and it allows us to cope with the increasing complexity of models by dividing them into substructures and deriving their structural dynamics independently. This allows an improvement in computational...

Numerical modeling of wave run-up on a dike: Simulations with the VOF-model ComFLOW

Wave fields in the close vicinity of a coastal structure can be very complex, this is especially the case during extreme storm conditions and for complex geometries. There is a growing interest for numerical simulation tools capable of predicting in detail the complex hydrodynamic loads due to waves and currents and its effect at structures. In...

Jetty design at Rio Araranguá

Master project report. The hydraulic efficiency of the river Araranguá will be increased by the construction of jetties at the mouth of the river. The river tends to migrate from south to north which decreases the hydraulic efficiency and causes flooding upstream during events of high discharge. To stop the migration the construction of jetties...

Feasibility study on Delta Transway

Influence of vegetation on flow and morphology in the river Allier, France

Invloed van plaatsingsdichtheid op de stabiliteit van 'armour layers' van golfbrekers

Door de jaren heen is er veel onderzoek gedaan naar golfbrekers en de stabiliteit van de 'armour layer'. Hieruit is gebleken dat de plaatsingsdichtheid van de 'armour layer' elementen een belangrijke parameter is. De doelstelling van dit onderzoek is om inzicht te verkrijgen in de invloed van de plaatsingsdichtheid op de stabiliteit van kubussen...

Buenos Aires port expansion 2020

Economic outlook and capacity of the port The port of Buenos Aires has known a large growth of container throughputs in the last few years: in 1991 233,000 TEU were handled, in 1995638,000 and in 1998 over 1.1 million TEU were handled by the container terminals in Puerto Nuevo and Dock Sud. The end of this growth is not expected soon and various...
