During flood a lot of sediment is transported out of the catchment area. Major sources of sediment from the upland and storage along the rivers will be flushed down the river during flood. Its like cleaning the 'longkang' and drains during rainfall event. Studies on sediment transport from catchment shows that 80-90% of annual sediment flush down the catchment were from one or two flood events. This river cleanses will cause sedimentation in the coastal areas, affecting fisheries and corals.
