Abstract

In the last two decades underwater acoustics gave rise to many useful and promising techniques in different fields of environmental engineering. Single and multi beams echo sounders together with acoustic Doppler current profiler (ADCP) nowadays appear to be of primary importance for a reliable and detailed surveys of river channel morphology, bed forms, velocity and sediment transport fields, and therefore for the following calibration of two or threedimentional morphodynamic numerical models. This contribute aims to present some results from our experience on both technologies, derived from: the collaboration with ARNI and ARPA-SIM, regarding some novel techniques using ADCP for velocity and sediment transport fields have been tested since 2006 on the Po river; the on going experience inside CLARIS-LPB, the research project funded within the 7° FP concerning the climate change impact (CCI) assessment over la Plata basin, with the objective to evaluate CCI on river Paranà channel morphodynamics and therefore on its oceanic ship navigation way, by means of the most novel and reliable acoustic survey techniques and numerical models.
