Job title: Principal Scientist specialising in estuary process modelling.
Professional background: BSc Physics.
When did you join HR Wallingford? In 1987, straight after graduating.
How do you apply your knowledge? Having spent 20 years of flow and sediment transport modelling I now tend to lead teams applying these tools to, firstly, understand the key estuary processes at work in an area, and then demonstrating how these might be changed by a development or management intervention. Estuaries are a very important and diverse environment which are often under development or other pressures such as, for example, ongoing sea level changes. Application of appropriate modelling techniques can greatly help us understand or isolate the key aspects of a location and so focus our effort where it brings the most benefit or where the greatest risks or uncertainties lie. The present modelling tools, including 3D flow, sediment transport, water quality and morphological change models, allow us to investigate the impacts of human intervention on estuary processes and so inform ecological, commercial and societal impact assessment. However modelling alone can confuse matters without careful interpretation, assessment and presentation – this is where my knowledge and experience counts.
What do you enjoy about your work? After more than 25 years I can definitely say that the work is enjoyable! I often find myself working in a team, with colleauges or with partners and clients. This is one of the parts of my work I enjoy the most. Most days are interesting, with chances to think about new things that come along such as the recent example of modelling animal movement within the marine environment.
