Attributable human-induced changes in the magnitude of flooding in the Houston, Texas region during Hurricane Harvey
Using Fathom's US flood model to examine how climate change exacerbated the impact of Hurricane Harvey, which devastated Houston in 2017. We find non-linearities in the relation between precipitation increase due to climate change and the resultant flood inundation. In particular, increased flood volumes due to climate change in the most heavily flooded parts of Houston during Harvey were larger than the relative increase in precipitation. We estimate that roughly $13 billion of damages during Hurricane Harvey are attributable to climate change.

A simple inertial formulation of the shallow water equations for efficient two dimensional flood inundation modelling
A hugely influential paper that describes a new mathematical formulation of the equations used to describe the flow of water within 2D flood models such as LISFLOOD-FP. This reduced the time required to simulate a flood event on a computer by an order of magnitude and allowed the concept of high resolution continental and global scale models to be considered for the first time. This paper led to Professor Paul Bates being awarded the ‘Science of Risk’ prize by the Lloyds insurance market in 2012.
