المستخلص: This study focuses on giving a clear picture of the reality of climate water balance in Diyala province through the relationship between the rainfall and evapotranspiration on the other hand.This thesis came four chapters , the first chapter which include the theoretical framework and a brief review of the most important of the previous studies that are relevant to the subject of study.The second chapter included the study of impact (astronomical location , geographical location , topography , albedo , vegetation ) on the climate of the study area and the study concluded in this chapter that these controls are heavily influenced by all elements of the climate of the study area.While the third chapter included guarantees the study of the impact of climatic elements ( solar radiation , temperature , relative humidity, rainfall, evaporation , wind , dust storms ) on the climatic water balance , as the study found in this chapter that all these elements affect , directly or indirectly values that water balance.While Chapter fourth included calculated values of each of the evaporation / transpiration and water balance climate of the study area , which has been a set of equations by which to found those values , namely, ( equation Ivanov , equation Khosla , equation Thornthwait , equation Cottajn , equation Billy - Chridl , equation Najib Khrovh ) was applied equations of their area of study and two ( equation Ivanov , and the equation of Khosla ) shows the application of both equations on the study area to found the values of the evaporation / transpiration inherent to the study area suffers from a significant rise in the values of evaporation as the annual average of those values according to Ivanov equation (3077,6 , 2627) mm , respectively, for the stations (Khanaqin , Al khalias). either in the equation Khosla , reaching values (1368,2 ,1278,2) mm , respectively, for the same stations.Either in calculating the values of climatic water balance equations for both equations negative results except in the month of January has recorded station Khanaqin positive result amounted to (10,2) in the equation of Ivanov , and (11,1) in the equation o Khosla
