Complex Adaptive Systems & Urban Morphogenesis: Analyzing and designing urban fabric informed by CAS dynamics

This dissertation builds upon research that considers how cities operate as Complex Adaptive Systems (CAS). It focuses on how certain characteristics of urban form can support an urban environment's capacity to self-organize, enabling emergent features to appear that, while unplanned, remain highly functional. The main thrust of the work is to...

Mathematical modelling of morphological changes and hyperconcentrated floods in the Yellow River

Hyperconcentrated flow/flood is a water-driven sediment transport phenomenon, which is characterized by high sediment concentrations between normal sediment-laden flow and debris/mud flow. In a hyperconcentrated flow, strong interactions exist between water flow, sediment, and river bed, which may not only change the flow rheological properties,...

Long-term process-based morphological modeling of large tidal basins

The morphology of tidal basins includes a wide range of features developing along different spatial and temporal scales. Examples are shoals, channels, banks, dunes and ripples. Coastal engineers use their engineering tools to answer questions on the processes governing the short term (< decades) development of these morphological features....

Tidal Embayments: Modelling and understanding their morphodynamics

Tidal basins are observed all over the world's coastline, for example along the north coast of The Netherlands. These basins are important both from an economic and ecological point of view. Complex channel and shoal patterns can be found in these inlets, as they develop due to the interaction of the currents generated by tides, wind and density...

Advances in HDS catalysts design: Relation between catalyst structure and feed composition

The aim of this work is to propose a better understanding of ultra deep HDS for diesel, to contribute to the development of advanced catalysts. The characterization of catalyst structure was examined by XRD, TPR, TPS and Raman spectroscopy. The ranking of catalytic activities were tested using various model compounds, such as thiophenes and...

Morphodynamic modelling of estuarine channel-shoal systems

In this research, the initial formation and long-term evolution of channel-shoal patterns in schematised basins is simulated using a model based on the software package Delft3D. The resulting channel-shoal patterns are validated with field observations, among which the Western Scheldt estuary. This has proven that a complex model is able to...

Nearshore Bathymetry derived from Video Imagery

Owing to the economic importance of seasonal fluctuations in beach width and the frequent implementation of local beach and shoreface nourishments, coastal managers and scientists increasingly demand coastal state information at smaller spatiotemporal scales. Advanced, automated video techniques provide the means to collect such high-resolution...
