Abstract
The Lake Ha!Ha event is chosen as an example of extreme flow to highlight two key issues in numerical simulations of real events: the discretisation of topographical source terms in very irregular and evolving cross-sections, and the representation of morphological processes when erosion affects the river banks as well as the river bed. A finite-volume modelling framework is used to conduct the analysis first from a pure hydrodynamical point of view, and secondly by including morphological processes.
