During the 2010 flood in the Odra basin a measuring campaign was executed that produced a set of data on peak discharges. Flow measurements located near gauging stations were taken from a boat with an Acoustic Doppler Current Profiler (ADCP) equipped with a GPS. The paper presents a detailed analysis of the records, including referencing to ortophotomaps, to assess the quality of ADCP recording, local flow characteristics and finally to re-evaluate the total discharge values. Further, the flow is divided between the main channel and the floodplains, while the main channel in the case of the presence of groynes is additionally divided into a central zone between the groynes and zones of groynes. Partitioning of particular zones to the total discharge is calculated along with average and maximum local flow velocities. The study delivers data for the development of more reliable numerical modelling tools, which in turn may fulfil the measuring gaps in situ. It is shown that the modern field data acquisition GIS post processing, and numerical modelling support each other and improve the final overall result, bringing hydrologic products to a higher standard. The synergy of hydraulics and geoinformatics in hydrology is therefore highly recommendable.
