一、前言 近年来大规模水利建设愈益明显地表明,我国河流泥沙测验资料不全,精度不高,方法繁复,极需改进提高.悬移质泥沙测验精度和效率取决于测验仪器和测验方法,如过去珠江三角洲河口地区的悬移质测验,有六个控制断面,每施测一次全潮输沙率需采取一万多个水样,水样处理工作量庞大,资料计算浩繁,几致使工作无法进行.普通河
I. INTRODUCTION In recent years, large-scale water conservancy construction has become more and more obvious that the information of river sediment test in our country is not complete, the accuracy is not high, the method is complex and it is very much needed to improve and improve.The accuracy and efficiency of suspended sediment test depends on the test equipment and test methods For example, there are six control sections in the suspended sediment test in the estuary area of the Pearl River Delta in the past. When the total tidal sediment transport rate is measured, more than 10,000 water samples need to be taken. The workload of water sample processing is huge. Work can not be done. Ordinary river
