Research interests

Andrew’s research interests are in fluvial geomorphology with a particular focus on river and floodplain hydraulics, bedload and suspended load transport, and fluvial landscape evolution. Methodologically, much of his work involves mathematical and numerical modelling, with a strong emphasis on the integration of theoretical and empirical approaches
