The Caspian Sea level changes were very high in various periods of time; alternatively decreasing and increasing. Since the Caspian Sea level changes generally are remarkable in the short period of time, shoreline forward and retreat will be large due to the fluctuation of sea level; so, the prediction of shoreline changes is very important in the Caspian Sea. Bruun has presented his theory under the title of Bruun rule for shoreline change prediction; this rule is related to sea level rise, closure depth, distance from the coastline to closure depth and the maximum vertical run-up excursion above the point of bore collapse parameters. Also, Rosati et al. applied landward transport to the Bruun rule for improvement of its prediction that achieved the most favorable results.

In this research, the Bruun rule and modified Bruun rule extended for landward transport has been investigated for the Caspian Sea. In this study, the modified equation has shown the better results, which suggests that landward sedimentation could be the result of the Sea level changes as well as natural storms during the years
