The objective of this work was to validate SPreading Liquid Over Terrain (SPLOT), LSMS and OVERTOP against experimental bund overtopping data, in order to gain confidence in the model and/or highlight any possible shortcomings.
Bunds around liquid storage tanks are generally designed so that they will retain more liquid than is contained in the tanks within them. A slow leak will therefore be contained. However, a sudden catastrophic tank failure will result in a surge of liquid, some of which may overtop the bund. Analysis of hazards allowing for this possibility therefore requires an estimate of how much liquid will overtop the bund.
