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.

Acoustic measuring of stream flow and sediment transport to assist river morphodynamics modelling
The possibility of collecting a large amount of good quality data in a relatively short time has become more and more
feasible over the last decade. Measurement techniques has been pushed to their limits so that equipment, which was
known for its use in the laboratory, has been successfully applied in the field. As an example it can be mentioned that
since years micro Acoustic velocimters (ADVs) are used in rivers, and recently, a laser based particle image velocimerty
system, PIV, has been used in a shallow lowland river. Also post processing tools have emerged and applied to large
amount of data. One possible use of this large amount of temporal and spacious data can be the verification of numerical
models. This paper aims to present cases where advanced acoustic monitoring techniques have been used and newly
developed to gather a large amount of data to verify numerical models. These numerical models were both hydrodynamic
and with coupled sediment transport. This study will reveals facts from single and multi-frequency acoustic monitoring
(acoustic Doppler current profiler) of flows and suspended load concentrations in the Po and Parana rivers in Italy and
Argentina, respectively.
