Abstract
Extensive field investigations, sampling and laboratory studies have been done on soil samples from Khuzestan province in order to document their dispersivity and the distribution of dispersive soils. Geological conditions in different parts of the province show that the high relief areas in the north, northeast and eastern parts of the area are eroded by rivers and form deposits in the Khuzestan plain. Due to special conditions, the existence of dispersive soils in different parts of the area is not avoidable. Based on results of field investigations and laboratory results, the studied area is divided into three zones, wilt high and moderate dispersivity potential, and a floodplain with nondispersive soil. In addition to the different laboratory tests for identification, the dispersive soils have been compared with each other and related to the field conditions.
