As result of density difference between seawater and fresh water in coastal aquifers, a transition zone between two fluids is formed. A wedge of saltwater can be entered in coastal areas to the aquifer. Seawater intrusion rate and extent of transition zone depends on several factors including: changes in sea level, aquifer characteristics, hydrologic conditions of upstream, discharging from the aquifer, tidal and seasonal fluctuations of sea water. In this paper height of interface between seawater and freshwater in Mazandaran coastal aquifers is calculated by relationships that have been used in previous researches. According to available information, (maximum seawater intrusion) in sections of Mazandaran coastal aquifers and allowable development of exploitation of this area have been calculated. Results show that development of exploitation is not possible for section A, B and O among total sections of Mazandaran coastal aquifers.
