Water and sediment regulation scheme (WSRS) is an annual water conservancy project which aims to alleviate sand depositions and reduce flood risks in the Yellow River of China since 2002. There are few researches on the sand bar within Yellow River tail channel and its estuary from each WSRS effect, though these relative researches are important to be carried out for a better understanding of WSRS. By interpreting two GF-1 satellite images in the end of 2013 and the start of 2015 after carefully controlling some potential bias factors from the change of water level, precipitation or tidal, we compared and analyzed the change of sand bars by one WSRS implemented in 2014 in this paper. Our results indicated this WSRS changed obviously the area/shape of sand bars. It made the area of the river sand bar decreased totally by 5.55 km², while the estuarine sand bar increased by 2.08 km². And it achieved the highest scour efficiency (90.11%) in the straight channel, but it achieved the lowest scour efficiency (44.71%) in the more bends channel. From the prospect in the change of estuarine sand bar, the west side area increased, while the east side area shrank. There were some broken small sand bars on the north side and they were forming a large sand bar.

自2002年以来，水沙调节计划（WSRS）是一项年度水利项目，旨在减轻黄河中的沙粒沉积并降低洪水风险。黄河尾河道及其河口的沙洲研究很少。每个WSRS效果，尽管这些相关研究对于更好地理解WSRS至关重要。在仔细控制了水位，降水或潮汐变化引起的一些潜在偏见因素之后，我们通过解释2013年底和2015年初的两张GF-1卫星图像，我们比较并分析了一项由WSRS实施的WSRS的沙洲变化。 2014年本文。我们的结果表明，WSRS明显改变了沙洲的面积/形状。这使得河沙带的面积总共减少了5.55 km²，而河口沙洲增加了2.08 km ²。它在直通道中的冲刷效率最高（90.11％），而在更多弯道中的冲刷效率最低（44.71％）。从河口沙洲变化的前景看，西侧面积增加，而东侧面积缩小。北边有一些破碎的小沙洲，它们正在形成一个大沙洲。
