Annotation	In many industrial applications (e.g. mining, dredging) or geomorphological applications (e.g. river control, stream restoration), transport of coarse solid grains in flow of water must be considered and evaluated. In order to assess the transport successfully, granular support mechanisms must be analyzed and their effect on the flow of the solid-liquid mixture quantified. Particle-laden flows carrying particles at high volume concentrations establish a layered internal structure and occur in the form of sliding-bed flows in pressurized pipes and in the form of sheet flows in open channels with mobile beds. Results and developments are discussed of our work on physical and mathematical modelling of such flows and their internal structures. The results include experimental observations from pipe- and flume set-ups in two laboratories in Prague. Furthermore, present and future activities are outlined of our research work in this field.
