Liman is defined in Bulgarian, Ukrainian (лиман), Russian (лиман) and Romanian (liman) as an enlarged estuary formed as a lagoon at the wide mouth of one or several rivers, where flow is constrained by a bar of sediments, as in the Dniester Liman or the Razelm liman. A liman can be maritime (the bar being created by the current of a sea) or fluvial (the bar being created by the slowed or turned flow of a sediment-saturated river).[1] The term describes many wet estuaries in the Black Sea and the Sea of Azov; a synonymous term guba (губа) is used in Russian sources for estuaries of the Russian shores in the north.[2]
