     due to the increasing use of the sea, marine pollution is extremely important. in fact, stopping along the estuary shoreline fragmentation, progress through tabs (like the sea or inland river entrance to the sea) is. the diffusion of pollution in estuary affect to the density and diversity of biological organisms in the aquatic environment. to study pollution diffusion on mahshahr estuary using the analysis of data and numerical modeling (advection dispersion module of mike21 software), simulate the effect of increasing geometric dimensions estuary (length, depth and width) was investigated on pollution diffusion. effect of change factors the estuary geometric on pollution was run out five different modes (including different depths and widths in the specified locations), and results were as follows: increasing estuary length was caused decrease pollution in all parts estuaries. increase estuary depth and current velocity (high water)  were resulted to decreasing pollution in the estuary. increase estuary depth and current velocity decrease (high water) were resulted into increased pollution in the estuary. increasing estuary width was caused increased pollution in estuary. thus, according to the geometrical estuary dimension mahshahr, diffusion of pollution in the estuary was investigated. thus, prediction effects physical factors (geometrical factors)  on diffusion of chemical agents (pollution) became possible.
