High resolution multibeam and hydrodynamic datasets of tidal channels and inlets of the Venice Lagoon

Tidal channels are crucial for the functioning of wetlands, though their morphological properties, which are relevant for seafloor habitats and flow, have been understudied so far. Here, we release a dataset composed of Digital Terrain Models (DTMs) extracted from a total of 2,500 linear kilometres...

Summary:Tidal channels are crucial for the functioning of wetlands, though their morphological properties, which are relevant for seafloor habitats and flow, have been understudied so far. Here, we release a dataset composed of Digital Terrain Models (DTMs) extracted from a total of 2,500 linear kilometres of high-resolution multibeam echosounder (MBES) data collected in 2013 covering the entire network of tidal channels and inlets of the Venice Lagoon, Italy. The dataset comprises also the backscatter (BS) data, which reflect the acoustic properties of the seafloor, and the tidal current fields simulated by means of a high-resolution three-dimensional unstructured hydrodynamic model. The DTMs and the current fields help define how morphological and benthic properties of tidal channels are affected by the action of currents. These data are of potential broad interest not only to geomorphologists, oceanographers and ecologists studying the morphology, hydrodynamics, sediment transport and benthic habitats of tidal environments, but also to coastal engineers and stakeholders for cost-effective monitoring and sustainable management of this peculiar shallow coastal system.

F.M., F.F. and A.K. wrote most of the paper and organized, coordinated and personally contributed to the acquisition and processing of the MBES data and to the organization of the database. C.F. contributed to the writing of the paper and applied the hydrodynamic model SHYFEM to the V.L. to produce the current fields and tidal correction data. N.M.P., M.R., C.M. and L.S. validated the bathymetric dataset for the areas included in the IIM cartography and wrote the description of the CUBE validation. E.C. developed the processing protocol, participated to the data acquisition and contributed to process the MBES data and to the structuring of the geodatabase. V.G. participated to acquisition and designed the geodatabase for storing the data. A.M. and A.P. participated both in acquisition and processing of the MBES data. M.B., D.B., G.L., F.M., C.P., A.R., F.R., M.R., M.S., V.M. participated to the acquisition of the MBES data. S.F., L.J., E.K., E.L., A.M., G.M.G., M.P., A.S. participated to the processing of the MBES data. T.M. was responsible for the MBES data storage and back up. G.U. developed the finite element hydrodynamic model SHYFEM and contributed to produce the water levels for tidal correction and the current fields. F.T. conceived the idea, contributed to the writing of the paper and supervised the work in all its phases.
