在潮沟下游 ,横跨且垂直与潮沟的横断面设了 5个观测站 ,进行了 2 4h的水动力测量。结果表明 ,涨落潮流速流向不对称。在潮沟内 ,涨落潮流流速差别很大 ,涨潮流流速最大为 9cm/s,而落潮流流速最大可达 38cm/s。据推测 ,潮沟内之所以落潮流流速明显大于涨潮流流速 ,可能是由于潮沟与岸线斜交有关。由于潮沟与岸线斜交 ,构成了更大的汇水面积 ,从而使得落潮时海水向潮沟内汇聚 ,故落潮流流速大增。
In the downstream of the tidal flats, five observation stations were set up across the vertical section of the tidal channel, hydrodynamic measurements were made for 24 hours. The results show that the tidal current velocity is asymmetric. In the tidal ditch, the tidal current velocity varies greatly, up tide flow rate of 9cm / s, and the tidal flow up to 38cm / s. It is speculated that the reason why the trend of the tide ditch tide flow is significantly greater than the tide tide flow rate may be due to the tide and the shoreline bias related. Due to the crossing of the tidal channel and the shoreline, a larger catchment area is formed, so that the seawater in the tide ebbs and flows into the tidal channel at the time of ebb tide, so that the flow velocity of the tidal current greatly increases.
