Recognition of growth pattern and folding mechanism in the fold-thrust belts with hydrocarbon resources is important in exploration and development planning of oilfields. As the processes of tectonics, erosion, and geomorphology impact on each other, therefore, the investigation of a process, one can obtain information about the other process. In this research the tectonic process of transverse growth of fold, was investigated based on the erosion pattern of the streams on the fold limb and geomorphological and hydrological indices in the Khaviz oilfield which is located in the Dezful Embayment. The results of investigation of the erosion pattern of the streams and the indices showed that the fold growth pattern in this oilfield in the south limb is limb lengthening through the toe and in the north limb is lengthening through the crest and toe.
