Abstract: “Soil Water content plays an important role in global hydrological cycles and regional climate of development weather patterns, plus its take part on production of precipitation and climate change. The aim of this work is to determine the effect of some of meteorological elements on the volumetric soil water content at the first level of the soil (0.0 - 0.07 meter) and study volumetric soil water content for four levels of the soil, and the extent of the volumetric soil water content change at the first level, including with time for four selected areas of Iraq Baghdad, Basra, Mosul and Rutba and four months January, March, July and September during the 33- year period from 1979 to 2011. Work was performed with monthly data relative humidity, surface wind speed at a height of 10 meters and the volumetric soil water content for four levels of the soil. And taken from the European Center (ECMWF), specifically model (ERA- Interim), by taking advantage of some statistical techniques such as”
