This paper takes Xiamen Rail-cum-road Bridge which locates at sea shoal for example. By observing water flow, suspected sediment and seabed surface sediment together with the geological and engineering environment in the sea area, the paper analyzes the sediments source, transportation tendency and variation of old and new submarine landform. It also calculates the sediment scouring and predicts the scouring amounts and provides scientific basis for indispensable bridge piers' protections along with to keeping the channel unblocked.
