Abstract

The paper deals with the morphodynamics of the artificially engineered outlet of the Vistula River, Poland. The delta is a coastal form typical of semi-closed micro-tidal or non-tidal seas, such as the Baltic Sea. This accumulative sandy form in front of the Vistula mouth constitutes a serious obstacle to the flow of water and sediment at the river-sea interface. Therefore, regulation works need to be carried out periodically. The present mathematical modeling applies the representative flushing discharge accompanied by marine hydrodynamic processes to particular variants of regulation of the Vistula mouth. The envelope method of analyzing the modeled bottom changes is used to formulate practical conclusions. The major findings concern the optimal extension of the breakwaters at the river mouth, sufficient to ensure the outlet patency.

优化维斯瓦河入海处的管理

本文论述了波兰维斯瓦河人工出口的形态动力学。三角洲是波罗的海等半封闭微潮或非潮海的典型海岸形态。维斯瓦河口前的这种堆积沙地形态严重阻碍了河海交汇处的水流和沉积物。因此，需要定期进行调节工程。本数学模型将具有代表性的冲洗排放以及海洋水动力过程应用于调节维斯瓦河口的特定变量。采用包络法对模型中的底部变化进行分析，从而得出实际结论。主要结论涉及河口防波堤的最佳延伸，足以确保出口的通畅。

期刊介绍： Continental Shelf Research publishes articles dealing with the biological, chemical, geological and physical oceanography of the shallow marine environment, from coastal and estuarine waters out to the shelf break. The continental shelf is a critical environment within the land-ocean continuum, and many processes, functions and problems in the continental shelf are driven by terrestrial inputs transported through the rivers and estuaries to the coastal and continental shelf areas. Manuscripts that deal with these topics must make a clear link to the continental shelf. Examples of research areas include: Physical sedimentology and geomorphology Geochemistry of the coastal ocean (inorganic and organic) Marine environment and anthropogenic effects Interaction of physical dynamics with natural and manmade shoreline features Benthic, phytoplankton and zooplankton ecology Coastal water and sediment quality, and ecosystem health Benthic-pelagic coupling (physical and biogeochemical) Interactions between physical dynamics (waves, currents, mixing, etc.) and biogeochemical cycles Estuarine, coastal and shelf sea modelling and process studies.
