A simple raster-based model for floodplain inundation
A seminal paper (with almost 1000 citations in the academic literature) that offers the first description of a grid-based 2D flood model. This format underlies most contemporary 2D flood models, and the engine at the heart of the Fathom models has its origins in the first ‘LISFLOOD-FP’ model described in this paper.

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.
