Abstract
An accurate representation of linking processes between one-dimensional (1-D) and two-dimensional (2-D) models is of particular importance for many flood- modelling projects. This paper provides a comparison of 1-D/2-D linking methods used to simulate a hypothetical embankment failure. Comparisons were made by implementing 1-D/2-D linked models using two different 1-D/ 2-D linking methods, namely water levels and discharges, using both the alter- nating direction implicit (ADI) and total variation diminishing (TVD) 2-D numerical schemes widely used in flood models such as Flood Modeller Pro (http://www.floodmodeller.com). The flood inundation levels and extent pre- dicted by each numerical scheme were similar when the discharge method was used to link the models, whereas they were dependent on the numerical scheme when the water-level method was used. Consequently, where decisions affecting public safety are informed by the modelling, such as evacuation following a breach, it is recommended that the discharge-linking method should be used for linking models
