Ship locks are the most widely used, promising, and important type of navigation structure in the world at present. It is, therefore, crucial to evaluate the operation safety of a ship lock in service. However, the determination of indicator thresholds is challenging. Accordingly, this paper describes the systematic study of the evaluation system of ship lock operation safety. First, the safety accidents of ship locks are counted. According to the rhombic thinking mode (that is, the thinking mode of ‘first divergence and then convergence’), with the help of extenics, a multi-indicator hierarchical indicator system including 5 first-class indicators and 47 second-class indicators for the safety evaluation of ship lock operation is established, and 4 safety evaluation grades are classified: normal, deterioration, early warning, and shutdown. The threshold range of each indicator at each grade is determined individually. Second, based on the idea of multi-factor optimization and integration, the process and the matter-element model of ship lock operation safety evaluation based on extension theory are proposed. Then the weight of the safety indicator is determined by the combination weighting method. The evaluation result is consistent with the actual situation.

“…At the same time, when determining the location of a given barrage, multi-faceted analysis plays an important role, where the technical, environmental, transport, economic, social, and functional criteria are taken into account [4]. It is worth adding that when studying ecological factors, it is necessary to consider the impact of navigation on the river ecosystems, determining the spatial distribution, potential risks and drivers of river health, but also to present the programs for ecological conservation and sustainable river management based on detailed studies [12].…”

Retention reservoirs are one of the basic elements of water management. Multifunctional, they are used for flood protection, drought prevention and other purposes. Water reservoirs can also play a fundamental role in improving navigability on the lower section of the Vistula River from the Włocławek barrage to the mouth of the Gdansk Bay. Their implementation is a determinant for the possibility of restoring the economic role of the river in question. Therefore, the purpose of this research was to determine the current navigation conditions and the state of the regulatory buildings on the Lower Vistula. The investments necessary to achieve international parameters of the waterway were also determined, together with the calculation of financial benefits related to their implementation. This was possible based on the conducted bathymetric measurements, spatial analyses, economic calculations and queries of the obtained studies. It was established that fairway depths of 1.4 m are ensured for 180 days per year on average. On the other hand, the construction of five barrages (Siarzewo, Solec Kujawski, Chełmno, Grudziądz and Gniew) will make it possible to achieve at least a navigability class IV (international) on the section of the Vistula River waterway. In addition, the barrages will enable the retention of 1.2 billion m3 of water and will be associated with financial benefits such as shipping use, flood protection and counteracting the effects of drought. On this account, annual revenues may amount to approximately PLN 3.5 billion. This shows that the construction of the reservoirs is profitable, and the proposed solutions should be implemented in the context of sustainable water management and adaptation to climate change.
