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.

Water management requires a good understanding of sediment transport and associated river morphodynamics. In mountain and piedmont hydro-systems, gravel-bed rivers often transport large amounts of fine (silt-sized) sediment. The bed material can be regarded as a mixture of coarse (gravels) and fine particles (silt, clay, very fine sand). Whether they are transported separately or not cannot be answered simply, because complex interactions between these two classes of
sediment exist. As a consequence, the riverbed is usually made of heterogeneous layers of gravel particles clogged by fine sediment infiltrated in the pores of the matrix. The hydraulic conditions for the deposition and erosion of such sediment mixtures are poorly known, although they are highly related to ecological (affection of riverís habitat) and socioeconomic
issues (dam management).
