Methods for determining the speed of water flow in canals in order to protect the slopes and bottoms of canals from collapse

Abstract

The paper analyzes the navigating conditions of the displacement type ships for the transport of our shipping companies on the channels of the Danube-Tisa-Danube hydro system in order to determine the navigation speed at which the speeds of water flow of opposite direction occur so that the channel banks and the bottom are protected from collapse. The methods applied in the work were created as a result of special research conducted on the Moscow and Volga-Don channels by two scientific institutions of the Russian Federation: the Main Research Institute of Water Transport (GIIVT) and the Scientific Research Institute of Water Transport (NIIVT). The results of this research have been published in literature in the Russian language. The aim of the authors was, based on these published methods, to examine and determine the impact of the movement of ships of our shipping companies on the shores and bottom of the canal as a new step in preparations for finding the optimal regime of navigation on navigable canals. Self-propelled (motor) ships for the transport of cargo of different types in channels of variable cross-sectional area and at different navigation speeds were subjected to calculations.
