The research conducted at the Chair of Transport Processes in Hydro Systems is focused on investigating the dispersion of substances, both particulate and dissolved, in aquatic ecosystems and anthropogenically influenced settlement areas. Our goal is to gain a fundamental understanding of the underlying processes at the microscale, which are crucial for larger-scale engineering applications. To achieve this, we employ a research approach that combines flow simulations and laboratory investigations of multiphase systems. These studies help us characterize the macroscopic material properties involved in the complex transport processes. Through our research, we aim to contribute to advancements in environmental science and engineering with practical applications for sustainable resource management and environmental protection.
