Corporate name TU Braunschweig Project Floodsite Date 2009-06-24 Abstract Results showed that the existing model on erosion of clay with water-filled cracks (Führböters theory) which only considers cohesion as the soil strength is only applicable for certain conditions. The model should consider other resistant forces such as soil weight and pore pressures. From the tests on clay without water-filled cracks, it concludes with the limitation of recommended water contents which shows the most erosion resistant behaviour. This new limitation covers both operational and functional aspects which has narrower range than previously reported. Other approaches involving theoretical and operational aspects were also discussed to describe the erosion mechanism and to develop a methodology for further research and development. Other experiments to investigate the possibility of dike breaching initiated by breaking wave impacts have been carried out using small wave flume. A dike model built from sand as core and clay as its cover was subjected by the wave impacts generated by the flume. This qualitative experiment was intended to investigate the mechanism of clay cover failure and breaching possibility initiated by the breaking wave impacts. Seven stages of dike failure mechanisms initiated by breaking wave impacts are identified that lead to severe damage of the sea dike.
