Is the intensity of damage the same on all flooded agricultural fields?
NO, the intensity of damage provoked by a tsunami depends on three main characteristics at that particular location: the energy of the flood, the type of soil coverage and vegetation, and the soil hydraulic properties including drainage capacity. The energy of the stream coming in and stream receding at a particular location influences the erosion and physical destruction. The energy is mainly related to the velocity of the stream but also to the stream load in sediment and debris. As a result of the high energy along the first inland stretches it is likely that erosion is very high, however, when the wave penetrates further inland the energy decreases (velocity diminishing) and that results in a deposit of sediments. The type of soil coverage in the affected fields influenced the velocity of the water. In general, a bare soil is likely to experience high velocity and therefore higher erosion, whilst a dense coverage and small trees will absorb energy and reduce the velocity of the wat
