Study on Characteristics of Flow and Sediment for Xiaomiaohong Tide Inlet in Radial Sand Ridges

Abstract:

Based on the measured hydrological data and the established mathematical model of Xiaomiaohong channel, the current and sediment distribution characteristics are researched and analysed. Some conclusions are drawn as follows: (1) The maximum velocity and mean velocity of the measuring points in the groove were generally greater than those at points in the open waters; spring tide and neap tide strength difference is apparent, spring tide should play a major role in the beach evolution. (2) Suspended sediment concentration in the open sea is significantly lower than that in the tidal channel; the bottom sediment concentration is generally greater than surface, bottom surface sediment concentration is 1.12 ~ 1.66 times (3) Median particle diameter of suspension sediment is 0.005 ~ 0.017, mainly for fine silt and very fine sand.
