In this research a broad assessment of the geological, sedimentological and geotechnical characteristics of the coastal Holocene sediments of the Anzali Area was made and three engineering geological units as Upper Sandy Zone (USZ), Middle Clayey Zone (MCZ) and Lower Sandy Zone (LSZ) were identified. These units are the consequences of rapid sea-level fluctuations of the Caspian Sea in the Holocene. The engineering geological characteristics of these units were analyzed and the main engineering geological problems associated with sediments of each unit were identified. The results show that USZ has high liquefaction potential, low bearing capacity, settlement susceptibility and excavation problem. MCZ has low bearing capacity, high settlement susceptibility and excavation problem. LSZ that has good geotechnical properties poses few problems.
