黄委会济南水文总站于一九八四年五月中旬,在黄河口地区进行第一次大规模同步水文泥沙因子测验。包括十三米水深以浅的滨海区,布设八个断面,十条垂线。参加这次测验调集了十二条机动船近一百人,同步连续观测三个昼夜。测验中使用394型高精度无线电定位仪定位,ZSX——Ⅰ型直读式流速流向仪测速和流向。共取得2772个测点流速、流向,1386个测点含沙量,1386个测点温盐度资料,还进行了水深、潮汐、气象、透明度、水色等项目观测。这是黄河口开展观测工作以来 Yellow Hydropower Jinan Railway Station in mid-May 1984, the Yellow River estuary area for the first large-scale simultaneous hydrological and sediment tests. Including the water depth of 13 meters shallow coastal area, laying eight sections, ten vertical lines. Participate in this test mobilized a total of 12 motor boats nearly 100 people, simultaneous observation of three days and nights. The test uses the 394 type of high precision radio locator positioning, ZSX - Ⅰ type direct reading flow velocity meter speed and flow direction. A total of 2772 measured points flow rate, flow, 1386 sediment concentration points, 1386 temperature and salinity data points, but also for the depth of water, tide, weather, transparency, water color and other items observed. This is the Yellow River Estuary observation work since
