摘要：The environmental effect of the tidal bore propagation in kampar river is investigated. Propagation of the tidal bore satisfy Korteweg and de Vries (KdV) equation where the environmental effect will be given as a perturbation term of the KdV equation. The environmental efects taken into considérations are river discharge and bottom sediment. The result show that a river discharge that flow opposite to wave motion will give the damping effect that is decreasing of the wave velocity and the amplitude. The bottom sediments will give the damping effect so that a fine bottom sediment would cause the waves propagte slower than coarse sediment.
