Abstract The investigation focused on the non-migrating mid-channel bars that emerged in the river channel as a consequence of river engineering. A reach of around 280 km of Middle Vistula River (Poland) was taken into account as the study site. The most vivid examples of the river engineering works potentially influencing the river channel are the ferry crossings. Along the Middle Vistula River reach, there are 17 ferry crossings that were constructed from 1970s to 1990s. A cartographic analysis was carried out to determine the influence of the ferry crossing construction over the river channel. It was performed on the basis of aerial photographs (traditional aerial photography and UAV photography). In 3 out of 17 potential localizations, the emergence of large non-migrating mid-channel bars was observed. A study of cartographic materials (from 1950s to 2000s) allowed determination of the dynamics of those bars, including time of emergence and the changes of their size.

对渡口桥台施工响应的中维斯瓦河中段坝体动力学

摘要 调查的重点是河道工程中出现的非迁移性河道中坝。大约 280 公里的中维斯杜拉河（波兰）被视为研究地点。可能影响河道的河流工程最生动的例子是渡口。沿着中维斯杜拉河河段，有 17 个渡口，建于 1970 年代至 1990 年代。进行了制图分析，以确定渡口建设对河道的影响。它是在航拍照片（传统航拍和无人机摄影）的基础上进行的。在 17 个潜在定位中的 3 个中，观察到大型非迁移中通道条的出现。
