The paper refers to a field study of river bed pattern in a large sand river (i.e Po river in Italy) at medium flow condition during two bathymetric measurement campaigns. The selected straigth reach extends overall 2.6 km. Within the reach a representative large area of active bed (more than 0.1 km wide and 0.65 km long) was surveyed with a Multibeam Echo Sounder (MBES) during two different flow condition (19th June and 7th July 2014). In each campaign the survey was repeated at different subse- quent time in order to derive bed form kinematics. Bed form pattern was analyzed and different geometri- cal approaches were applied to estimate bed-form sediment transport component. Results are compared with standard sediment transport formula.
