1. Internal Erosion Phenomena in Embankment Dams : Throughflow and internal erosion mechanisms
Abstract : In this study, two major internal erosion initiation processes, suffusion and concentrated leak mechanisms, which lead to both defect formation in a dam’s body and its foundation and high throughflow in dams subjected to internal erosion were studied. This understanding has the potential to facilitate numerical modelling and expedite dam safety assessment studies. READ MORE

3. Impact of Surface Structures onDeposition and Erosion in a Tokamak
Abstract : Fusion is a potentially unlimited and environmentally friendly energy source for human society in the future. However, along the way towards the application of fusion energy there are still unresolved complications. Among them, deposition and erosion are two critical issues. READ MORE

4. Swash Processes and Dune Erosion: Emphasis on Vessel-Generated Waves
Abstract : In navigable waterways, owing to the relatively short fetches for wind wave generation, the free waves generated by moving vessels often produce the dominant wave action with respect to erosion of the shore. In response to the fairly recent introduction of high-speed ferries, combined with a planned expansion within the passenger- and car-carrying ship market, the need to model and predict coastline changes as a result of exposure to vessel-generated waves has become a topic of increased research.

5. On failure modelling in finite element analysis : material imperfections and element erosion
Abstract : This dissertation concerns failure modelling with material imperfections and element erosion in finite element analyses. The aim has been to improve the element erosion technique, which is simple to use and implement and also computationally inexpensive. READ MORE
