黄河口尾闾河道汊3以下断面地形数据（2019年8月）

2019年8月现场实测的黄河口汊3及以下1#至16#共17个河道断面地形数据。断面高程观测：水面以下部分应用船载测深仪+RTK，测定河道断面高程，滩唇以上应用RTK进行测量，滩唇测量数据点间距不大于5m。

Topographic data of 17 river cross-sections, including the third distributary channel of the Yellow River Estuary and No.1 to No.16 cross-sections downstream thereof, were field-measured in August 2019. For cross-section elevation surveys, submerged segments of the river channels were measured using a ship-borne echo sounder integrated with RTK; elevations of areas above the beach lip were collected via RTK, with the spacing of survey points at the beach lip not exceeding 5 meters.
