Zuzana Nemetova (Slovakia) cooperated with Prof. Kazimierz Banasik from Warsaw University of Life Sciences. They worked on mathematical modelling of soil degradation processes and evaluation of flood protection measures within the territory of Poland and the Slovak Republic. The results from EROSION-3D model consisted of map and tabular outputs reflecting various erosion and transport processes (amount of runoff, sediment mass, sediment concentration, erosion, net erosion and sediment deposition). The results obtained will be published in the article.
