N2 - In order to estimate the amount of bacterial contamination in a soil (silty clay loam) treated with poultry manure, the mobility of E.coli bacteria was simulated using inverse modeling. The E.coli was selected for this study since it presents as a pathogenic bacteria in poultry manure. For this purpose, two equilibrium (CDE) and non-equilibrium equations (NECDE) were numerically solved using HYDRUS-1D code and inversely calibrated with a laboratory experiment data. The NECDE equation could predict E.Coli mobility through the soil with more accuracy both in calibration and testing steps than CDE equation. The coefficient of determinations for NECDE and CDE equations were 0.99 and 0.91 for calibration step, and 0.97 and 0.98 for validating step, respectively. Therefore, NECDE equation with using inverse modeling could be a reliable equation for simulating E.Coli transport through the soil.
