Analysis of the Spatio-Temporal Evolution of Dredging from Satellite Images: A Case Study in the Principality of Asturias (Spain)

One of the fundamental tasks in maintenance port operations is periodic dredging. These dredging facilitate elimination sediments that coastal dynamics introduce. Dredging are increasingly restrictive and costly due to environmental requirements. Understanding condition seabed before after essential. In addition, determining how has behaved recent years important consider when planning future operations. order analyze behavior sediment transport changes sedimentation, studies littoral conducted model deposition sediments. Another methodology could be used real would study compare bathymetries collected periodically. The problem with this it requires numerous bathymetric surveys produce a sufficiently significant analysis. This provides an effective solution for obtaining dense time series bathymetry mapping using satellite data, enables past examined. proposed work uses Sentinel-2A (10 m resolution) images obtain historical by development random forest algorithm. From these series, possible determine entry into area occurs. applied Port Luarca (Principality Asturias), extracting successive utilizing reveals once dock was dredged, were redeposited recovered its level prior less than 2 months.
