Engineering geology and geohazards of sefidrud delta, south caspian coast, north Iran

Abstract

The engineering geological conditions and geohazards of Sefidrud Delta were assessed using a stepwise approach. The approach included the geological, sedimentological and geotechnical studies of the area. First of all the sedimentary environments of Delta and their associated deposits were identified. Investigation and assessment of engineering geological characteristics of these deposits revealed that the most Holocene deltaic deposits have poor geotechnical conditions. Most of these deposits are associated with geohazards including liquefaction, erosion and land subsidence. © Springer International Publishing Switzerland 2014.
