Abstract


NON-STATIONARY MODEL OF NITRATE TRANSPORT IN AN EXEMPLARY CATCHMENT IN THE MGWB NO. 326 NORTH OF CZĘSTOCHOWA

Abstract. The paper presents basic assumptions and results of a non-stationary MODFLOW model of nitrate transport in the Kocinka catchment. A method of reconstructing temporally and spatially variable input function of pollution for two main contamination spots: agriculture and urbanized areas, is presented. The NLES4 software was used to assess loads of nitrogen leaching from agricultural areas. Presented are also: representation of denitrification process in the model, the results of its calibration and the modelled nitrate breakthrough curves.
