description <strong>A laboratory study was conducted to determine sodium desorption behavior from exchange positions of soil solid phase because of a quiet water flow. Using sulfuric water collected from a sulfuric spring and a chlorine water from Tigris river. The flow was through two disturbed soil columns. Soils were sampled from Fadhlia and Hamdania locations in Nineveh province/ northern Iraq. Waters flow were persisted for 240 minutes with 4 cm highness over soils surface was maintained. Leachates were collected every 10 minutes for a total ten extracts which analyzed for Na<sup>+</sup>. Three mathematical kinetic description were considered as an accumulative soluble Na<sup>+</sup>, Na<sup>+</sup> expressed by SAR and ESP concepts , sequences as parabolic diffusion, zero order, 1<sup>st</sup> order, Elovitch and power function (poly ordered) models were applied. Mathematical descriptions revealed succession of 1<sup>st</sup> order and power function models. Na<sup>+</sup> desorption coefficient rate values by 1<sup>st</sup> order model were ranged from </strong><strong>96 ×10<sup>-3</sup></strong><strong> -</strong><strong> 185 × 10<sup>-3</sup> minute for chlorine water, for sulfuric water were from 10 ×10<sup>-3</sup> - 34×10<sup>-3</sup> minute for both locations respectively, while </strong><strong>desorption coefficient rate values </strong><strong>according to power function model were 686 ×10<sup>-3</sup> , 683×10<sup>-3</sup> , 634×10<sup>-3</sup> mg.kg<sup>-1</sup>.min.<sup>.-1</sup> respectively. Results referred also that </strong><strong>Na<sup>+</sup> desorption coefficient rate values</strong><strong> was proportionally increased with waters ionic strength.</strong>
