Abstract

Advances in inundation modelling software, computer hardware and national data sets mean that it is now practical to use full solutions of the two-dimensional (2D) shallow water equations (SWE) to undertake national-scale modelling of breach inundation. Such modelling enables much improved asset management activities, which lead to reduced risk to life, lower risk of damage to properties and a much better targeting of investment by asset owners. This paper describes how a 2D SWE inundation modelling system was designed and applied to the UK Canal and River Trust canal system as part of a quantitative high-level risk assessment framework. The framework includes a new approach for estimating breach probability and hydrographs in the canal system for potential embankment and culvert failures. An innovative automated model build-and-run process using Isis 2D software was applied to model inundation in urban areas. Predicted likely loss of life and property damage outputs were used to generate a risk chart to prioritise asset inspection and maintenance.
