IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Flow resistance over plane bed with intense sediment transport
Author : V. Matoušek and J. Krupička
Flow resistance is discussed of mobile beds at high shear stress. Experimental data from both a pressurized pipe (own data) and a laboratory flume (Smart 1984 data) confirm a close relation between sediment transport and flow resistance. A mobile-bed friction formula is proposed for steady flows with intense sediment transport in the upper plane bed regime. The friction formula is derived from a transport formula of the MPM type and the Smart's data are in a very reasonable agreement with the proposed formula.
