Modelling of coastal infrastructure and delta river interaction on ionic Lucanian littoral

Coastal risk and related prevention and prediction activities are key topics in coastal environment planning and management connected to coastal erosion risk assessment, flood risk and coastal inundation. Further, moving up to general environmental impact, even related to risk assessment, the realization of human activities or infrastructures along the coast generally introduce drastic changes in longshore sediment rating and wave climate effects during both wave motion and storm surge. In such case, numerical models can be effective tools in local coastal planning, scheduling and management activities in both ordinary and emergency conditions. In fact, advanced and complex computational model availability allows numerical and graphical description of such scenarios aimed to define possible mitigation and contrast measures and or interventions by simulating alternative configurations/scenarios. In the paper the results of a medium-term morphological modeling of the interaction between marina and delta river, in ionic-Lucanian littoral in Basilicata region, are showed and discussed comparing the numerical outputs to observed changes of the local morphology gained by Lidar detection
