Abstract
Calculation of the flood zone during floods and natural disasters for the bridge crossing over the Bira River
Incoming article date: 13.07.2025The article provides a diagram of the possible flooding zone for the area adjacent to the bridge crossing over the Bira River. The calculations were performed on the basis of topographic survey data of the research area in the specialized program "Morphostvor 1". Based on the constructed morph, a flood zone was determined at the Estimated 1% high water level, which was 55.05 meters in the 1977 Baltic Elevation System. Based on the data obtained, flooding of the right-bank floodplain of the river was noted. Bira, but the flooding zone does not reach directly to the territory of the village. The constructed flood zone is schematic in nature and is intended for visualization of the hydrological situation in the studied area, this flood zone cannot be used for design decisions.
