## 5 Conclusions  
In this work we demonstrated the capability of an integrated methodology for the investigation of water and sediment transport in a tidal inlet with detailed spatial and temporal resolutions. By combining satellite-derived turbidity, continuous data from a network of monitoring instruments, instantaneous measurements of current velocity and

Satellite-derived turbidity proved to be useful for describing the surficial evolution of the lagoon-sea exchanges through the inlets, defining the suspended sediment distribution and dispersion pathways and tracing their origin and fate. Turbidity features at relatively fine spatial scale, such as small turbulent structures, as well as the effects of anthropic stresses such as dredging activities, were also clearly detected. With the recent launch of Landsat 9, combined with Landsat 8 and Sentinel-2 A/B, the aquatic science and end-user community can benefit from high-quality and consistent satellite-derived products for operational purposes at a one-to-three-day revisit time. As a paradigm of an extremely valuable environment at risk, the Lagoon of Venice represents a particularly interesting case study for sediment dynamics in response to natural forcing and man-made morphological transformations. In this context, there is an urgent need to find accurate, reliable and cost-efficient monitoring techniques to assess the impact of the recent construction of flood defence structures, such as the MoSE mobile barriers. The integrated system described and discussed here will be soon implemented in the other two inlets of Malamocco and Chioggia. Once completed, the observing network will enable the assessment of short-to-long-term variations on sediment transport pathways, the exploitation and enhancement of the existing data infrastructures and, real-time ancillary data permitting, also the assessment of the effects of moderate-to-extreme meteo-marine events. By adding in-depth observations, a robust and dense dataset will be available, providing more detailed and consistent information for the characterization of morpho-hydrodynamic processes. The multitude of available observational data might be of great help for research on aquatic science and for the end-user community. For instance, numerical models, which are usually based on simplified assumptions and do not necessarily reflect the actual complexity of natural processes, can be considerably improved by higher spatial and temporal resolution data. The ecosystem management practices will also benefit from these data for operational purposes, such as the monitoring of inlet morphological transformations and erosion and the planning of coastal defence. After the extensive morphological interventions operated at the Venice Lagoon inlets, and with the expected scenarios of sea level rise, the developed approach can also help to understand how the future regulation of the inlet flow introduced by the operation of the flood barriers will affect the sediment fluxes and, in the long term, the lagoon morphodynamics.
