| 摘 要： | 在潮沟下游，横跨且生趣与潮沟的横断面设了５个观测站，进行了２４ｈ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／２，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。

| Abstract: | Research into the hydrodynamics of the tidal channel near Well 101, Zhuangxi, Yellow River delta was carried out. Crossing the tidal channel, we have set up 5 stations and measured its hydrodynamic. It was found that the current velocities and current directions of flooding and ebbing tide are asymmetry in the tidal channel. A small flooding tide current velocity (smaller than 9 cm/s) and a larger ebbing tide current velocity (up to 38 cm/s) are found. The sea water converges toward the oblique tidal channel and makes a larger ebbing tide current velocity durring ebbing tide. |
