A geomorphic subdivision of the deltaic plain have been attempted based on studies of the Pleistocene history of the Caspian Sea, neotektonics in the SW Caspian Lowland, structural geomorphology of the delta, history of its relief and changes during the last century in particular. Four geomorphological zones are suggested to distinguish: 1) floodplain — channeled gently undulating deltaic plain, 2) hummocky deltaic plain, 3) gently rolling plain with koultuks (narrow bays), 4) fluvial marine undulating plain (delta shoreline and front).
