In the north-west part of Kolkheti lowland, there is located Samurzakano lowland. The Samurzakano wetland is extended on south, between Ochamchire and Anaklia. This territory is presented by the two terraces, which are separated from each other by the relief. On the upper terrace, which is spread along the sea shore on 5-10km and is risen over it by 20-25m.
The wetlands occupy small area, and are under the impact of natural drainage from existing valleys. The low terrace is presented as the area of accumulation of water, and therefor, accompanied bogging. The amount of the valleys crossing the upper terrace pass the lower terrace. The branches of rivers located here are gradually rising, caused by floods of these rivers. By this reason the whole low terrace is divided by middle rivers, which are presenting the closed areas. At the other side the second terrace is separated from the sea by the hill which is 1-2km.wide. The hill is formed by the dune and is risen 4-6m up the sea level. This hill resists the flow of rivers. So there are two types of wetlands on the second terrace. This type of wetlands were formed as a result of transgress when the lake-relicts were covered by the vegetation. The another ones were formed as a result of flooding in the lowland. The succession of the spreading of wetlands here is the same as on the Kolkheti lowland, namely: the open wetlands gradually passing into the unforested peatlands and further to the forested wetlands. The Samurzakano wetlands present sphagnum peatlands.
