Abstract:Laolonggou is a typical tidal inlet as a part of the barrier-lagoon system of the north Bohai bay.The threshold of the inlet is 2.1 km wide and over 20m deep,and the maximum flood current or ebb current through the threshold may be over 1 m/s.A dendritic tidal drainage system is well developed on the flood delta with little sediment accumulation.According to the morphology of terminal shoal,the edge of the ebb tidal delta is located around-11 m of water depth.A main ebb tidal passage is developed on the eas...
Keywords:tidal inlet  flood tidal delta  ebb tidal delta  mixed energy
