Salt Domes of Bastak, Hormozgan Province and its influenceon the soil and water Resources

Bastak Region is located in the northwest of Hormazgan Province. It is consideredas one of the poor regions of the country according to it's water resources while 7.24billion cubic meters of water run down to the sea in the form of waste water and floodsin Hormozgan each year without any further accessibility to it.Saline, alkaline and heavy ground water or the surface water flowing through thesaline formations are used for the irrigation of most agricultural territories of thisregion. However , the high level of ground water and severity of evaporation have stillreduced the soil fertility.On the other hand , the importance of water in this region increases with regard tothe dispersion of saline geological formations and improper quality of ground water.People suffer from the shortage of fresh and agricultural water most of the year. Thisregion is under the influence of two geological factors ie. The general folds of Zagrosmountaion chains and the phenomenon of diapirism.In addition to the saline and alkaline states of the soil, erosion has also largelyinfluenced on the decrease of its fertility. Therefore , this research mostly seeks for theeffective geomorphic evidence of the soil and water resources of the region while wehope to detect and offer some guidelines for it.Finally, salt domes are introdusing as one of the main factors of the salincty ofwater and soil in this region, We have used field activities and library and documentalmethods for achieving this purpose. Controling salinity plans should be implementedto prevent any further damage to the soil and water resources although manydifficulties are encountered when enforcing them due to several reasons. Thus, wehave tried to offer some reasonable suggestions base on two mechanical and biologicalstracthers for the reservation of soil and water resources according to regionalconditions.
