This research focused on the calibration of the Buildup and Washoff for dissolved iron. The test site located at the intersection of the Interstate-10 and Interstate-610, New Orleans, Louisiana. Storm water runoff from the examined elevated roadway section was analyzed for 14 storm events. The model used a linear function of antecedent dry time for the buildup model. The rating curve assumption was selected to estimate the pollutant transport capacity. In a further step the two were combined. The derived Buildup/Washoff model was calibrated for the collected data and precipitation data of the International Airport of New Orleans. The obtained power function for pollutant transport capacity is Y = 0.1028 * V 0.8212, where the transport capacity Y [ìg/l] and the total runoff volume V [l]. For the Buildup/Washoff model the 2 year interval gave the most reliable. The value of 12.13 mg/day was obtained for the Buildup Rate C.
