在研究河道演变和从事工程规划设计中,常常涉及到一个重要的问题—造床流量。但是,迄今人们对造床流量仍未有一个统一的认识。反映在平原河道的造床流量计算上,更是方法繁多。至于受洪、潮水双重作用的河口区,目前,仅有一种笼统的“多年平均落潮流量法。然而,我们在进行珠江河口区造床流量的计算中,缺乏的恰恰就是流量资料。 In studying the evolution of river courses and engineering planning and design, one of the most important issues is involved in bed flow. However, up to now, there is still no unified understanding of the volume of bed-making traffic. Reflected in the plain river bed flow calculation, but also a wide range of methods. At present, there is only one kind of general “multi-year average eddy flow method” in the estuarine area affected by floods and tides, however, we lack exactly the data of flow rate in the calculation of the volume of bed flow in the Pearl River estuary.
