The purpose of this research work is to investigate the role of factors involved in the soil moisture content of Shafaroud catchment area. For this reason, in the Google Earth Engine programming environment, by calling satellite data, land use maps were drawn for the 4 main classes of the mentioned basin, then the state of vegetation cover (NDVI), average temperature, evaporation and precipitation were checked and finally the soil moisture map was drawn. The results showed that the eastern half of the mentioned basin had different conditions compared to its western one, so that in the eastern half of the studied basin, most of the areas are covered by forest areas with 239 square kilometers, and towards the west of the basin, its density has decreased. This situation is also true for the vegetation cover. and the maximum diversity of vegetation was observed in the eastern half of the basin and its central areas at the rate of 0.55. All these factors have caused the soil moisture to increase in the eastern half and especially in the northeast of the mentioned basin and its value reaches 18.12 mm, on the contrary, in the western half of the basin and its northwest, the minimum soil moisture was observed as 12.62 mm. It should be noted that all factors showed a direct relationship with soil moisture, and among the mentioned factors, water vapor with an explanation coefficient of R2, 0.48, precipitation 0.41, temperature 0.22, and vegetation 0.11% have the highest role. in soil moisture.
