A liman (Russian: лиман) is an enlarged estuary formed as a lagoon at the wide mouth of one or several rivers, where flow is nearly fully or partially constrained by a mouth bar of sediments (peresyp), 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 insignificantly blocked estuaries of the Russian shores in the north.[2]

Water in a liman is brackish with a variable salinity: during periods of low fresh-water intake, wide-mouthed, deep examples will be greatly saline from inflow of sea water and evaporation.
