This paper presents the geomatic contribution to the hydrographical survey applied to the Arno River in Tuscany (Italy) that has been performed to obtain both underwater cross-sections as well as riverbank height using point cloud data from echo-sounder and terrestrial laser scanner so that water flow storage capability could be further estimated with high accuracy. The control network and ground control points design, measurement and adjustment are presented, describing the solutions adopted to face the specific needs of the project. The overall accuracy assessment is performed considering some known vertices: the results are fully compliant with the requirements for subsequent hydrological analysis.
