Abstract
Water balance techniques are a means of a solution of important theoretical and practical hydrological problems. The water balance equation for any natural area or water body indicates the relative values of inflow, outflow, and change in water storage for the area or water body. Estimating water balance in Iraq, depending on meteorological data and the Thornthwaite method, was the aim of this research. The results of corrected potential Evapotranspiration (PEc) obtained from applying the Thornthwaite formula were compared with annual and monthly rainfall in (32) meteorological stations to estimate actual Evapotranspiration (AE). The results showed that the annual summation of rainfall increased from the south-west towards north-east. According to the increasing ratio of rainfall due to the impact of the Mediterranean climate condition on Iraq. Actual Evapotranspiration depends directly on water excess during calculating water balance. The water surplus contour map indicates increased values towards the north-east direction of Iraq, where water surplus depends directly on both rainfall and actual Evapotranspiration.
