Flow-vegetation interactions in rivers:

PhD in Department of Geography, Durham University

Supervised by Prof. Rich Hardy and Prof. Jeff Warburton

NERC funded PhD research involved investigating the effects of vegetation on river flow. Vegetation is abundant in rivers and has a significant influence on their hydraulic, geomorphological and ecological functioning. The morphological complexity of natural plants (i.e. how plants looks to flow) is often neglected. I applied remote sensing techniques, designed laboratory-based flume experiments and used high-resolution numerical modelling (CFD modelling) to improve the process-understanding of flow-vegetation interactions at the plant-scale. The research focused on vegetation that intermittently interacts with river flow during flood events (i.e. floodplain and riparian vegetation).
