Soil salinity is an important issue that causes problems in soil fertility and crop production, especially in arid and semi-arid regions. This is why the study of soil salinity is important, and for track the changes, forecasting and early diagnosis is essential to use the proper tools. Urmia Lake is one of the regions that in recent years face the water retrogression, drought and soil salinity increase in surrounded areas. Thus, simulation of soil salinity to control and prevent its development is required. In this study, to determine the soil salinity, temporal changes of west side of the Lake in Dizaj-e Dowl area in four years period (2002-2005) were studied using SaltMod model and salinity level in the area was determined to be 17 ds m-1 and in transition zone and aquifer is 25 and 13 ds m-1, respectively. Which, low water table was one of the reasons that causes high salinity rate in transition zone.
