Assoc Prof David Dunkerley - Researcher Profile

Biography

My research spans a range of areas within the broad fields of geomorphology and hydrology. I work almost exclusively on modern landscape processes, including infiltration, the generation of surface runoff, and hillslope and channel erosion and sediment transport.

An understanding of modern landscape and environmental processes is a vital requirement for informed land management, and this need underpins much of my work.
