The hydrological conditions of a river have a direct impact on the possibilities for inland navigation and water sports. For inland navigation, in addition to the river’s hydrological characteristics and bathymetric conditions, it is important to know the extreme water levels, including minimum levels that may occur with a certain probability.
Maximum water levels in the estuary section of the Oder are well described in the subject literature, whereas less attention has been paid so far to the occurrence of low water levels. These are an important factor for navigation safety and directly affect the under-keel clearance of a vessel.
The aim of this paper is to characterize the low water levels of the Oder estuary section from Gozdowice to Świnoujście, which may have a direct impact on inland navigation. Determining water levels with a given probability of occurrence is necessary for the design of marine and river hydraulic structures, as well as for identifying the characteristics of storm-induced water level drops in river estuary sections flowing into the sea.
