The new concept for the heavy vehicles crossing in the large lowland riverbeds in the North East Strategic Direction

Abstract

The current method of crossing river channels by heavy vehicles involves engineering equipment such as the Motorized Floating Bridge. It has high efficiency when crossing regulated channels of large European Lowland rivers with stable hydrological conditions. In the case of unregulated rivers of the Polish Lowlands, this concept needs to be modified due to the high variability of water levels and the shape of the river bottom. This paper presents a new approach to crossing the channels of large lowland rivers by heavy vehicles. It is based on hydrological analyses and experience gained during many years of hydrographic, geological, and geomorphological studies conducted at the Department of Hydraulic Engineering and Applied Geology of the Warsaw University of Life Sciences (SGGW).
