Based on the hydrographic and sediment data, the characteristics of hydro-sediments and strait channel effects are analyzed. It is suggested that the flow shows the obvious characters of an to-and-fro current, the velocity is strong, the sediment concentration is low, the deposition is weak and the shore is on the balance status in the Maao strait channel. Under the joint action of the distributary and conflux of the tidal currents, the under water sprit develops in the little Nihujiao reef. This sprit is modified by the flood current from the under water shallow which is formed under the ebb current action. This sprit will further develop and form a tambolo, as a result of which the shore forms an arc smooth shoreline and reaches a new balance.
