Short summary
Thin coastal dykes found in developing countries may suddenly collapse due to land subsidence, material ageing, earthquakes, a collision with vessels, etc. Such a failure could trigger a dyke-break-induced tsunami. To analyse the potential consequences of such a flooding event, a hydrodynamic model was created using the data from the authors' field surveys of a vulnerable coastal community in Jakarta. The countermeasure of using mangrove forest is also proposed to mitigate violent floods.
