Gardab spring with an average annual discharge of 330 lit/s is counted as one of the important Karstic springs in the Andimeshk City. The aim of this study is surveying geological structures, morphological features and determination of factors affecting the manner of appearance, recharge and turbidity of the Gardab spring. In this regard stratigraphic studies, lithology, structural and morphological works have been done. The data obtained show that fractures, the Balarud faulting zone, faults in the region and the Chalab doline have basic roles in occurrence, recharge, turbidity and water transmission from the Chaoni Mountain and a part of the northwest of the Kooshab anticline to the Gardab (Mongereh) spring. Though, the topography and gradient of the Chaoni mountains are towards the Mongreh spring and convey water in the direction of it, but the main parameter governing water convey and turbidity are the Mongreh, Chareh and Verna faults. Based on gathered information, turbidity of the Gardab spring during rainfall is due to the Chalab doline.
