Overview

My research demonstrates the physical processes by which wood jams and vegetation affect flow, particle transport, and ecological health. I develop physically-based representations of these processes for modelling and design guidance using a combination of flume experiments, theoretical development and field observations, in order to improve the design and assessment of natural flood management projects and restoration interventions.

Structure and function of wood jams for natural flood management

Natural flood management practices, including engineered logjam installations, can promote floodwater storage and infiltration in upstream catchments, ehancing sediment storage and ecological resilience. Dr Follett's research considers the effects of engineered log jam installations on stream hydrodynamics and sediment transport in order to accurately assess the implications of natural flood management projects and guide management interventions.

Particle transport in vegetated canopies

The feedbacks between plants, flow, and particle fate shape the size, shape, and resilience of vegetated regions, which provide key ecosystem services to the landscapes in which they reside. Vegetation acts as an ecosystem engineer by creating distinct regions of flow diversion, turbulent mixing, and quiescent flow, dependent upon canopy physical parameters. The density and extent of vegetated canopies alters the canopy mediated flow profile, in turn influencing particle transport. In order to predict the resilience and future growth of vegetation, it is necessary to consider particle transport in light of the canopy-mediated flow environment. Dr Follett's research considers particle fate and transport in emergent and submerged vegetated canopies through laboratory experiments and numerical modeling, connecting transport trends to the physical parameters governing the canopy mediated flow profile, as well as particle size and density.
