Abstract: The Lower Seyhan Catchment Area starts at the downstream of the Seyhan Dam on the Seyhan River. This fertile area is exposed to dense agricultural activities. Nutrient loads (nitrogen and phosphorus) from these activities create an important pollution potential for surface and groundwater resources in the area. In addition to the agricultural areas, these nutrient loads also originate from domestic and industrial discharges. In this study, the transport of the estimated nutrient loads in the drainage channels was determined by mathematical modeling. In the modeling studies, the local hydrology and irrigation periods were taken in to account. In these calculations, a commonly used water quality simulation approach, QUALZEU was used for the prediction of parameter concentrations in the drainage channel network. Simulation runs were carried out for the summer and winter periods of 1992 and 1993.
