Monika Kalinowska is Associate Professor and Head of PhD Studies at the Institute of Geophysics Polish Academy of Sciences. Her main research interests are modelling the spread of pollutants in surface-flowing waters and numerical methods in fluid mechanics. She is a Member of the Water Management Committee PAS, the Geophysics Committee PAS, and the International Association for Hydro-Environment Engineering and Research IAHR.   Magdalena Mrokowska is Associate Professor and Head of the Hydrodynamic Models Laboratory at the Institute of Geophysics Polish Academy of Sciences. Her main research interests in environmental hydrodynamics include topics related to the transport of particles in marine and riverine waters: settling dynamics in density-stratified liquid and seawater with rheology modified by exopolymers, transport of sediment in open channels, with a special focus on microplastics.   Paweł Rowiński is Professor in Earth sciences and Director at the Institute of Geophysics Polish Academy of Sciences. His research interests include environmental hydrodynamics, mathematical modelling, and experimental studies of hydrological processes. He is Chair of the Europe Division Leadership Team of the International Association for Hydro-Environment Engineering and Research IAHR. He served as Vice-President of the Polish Academy of Sciences (2015–2022).
