Morphodynamics of Brazilian deltas

Deltas are geomorphological frameworks that exist at the interface between riverine and open water systems (marine or lacustrine). They are a common feature in the Brazilian coast due to sediment-rich rivers and Atlantic swell. This project seeks to investigate what factors control the morphodynamics of the São Francisco, Jequitinhonha, and Doce deltas inlets and their adjacent shorelines on the Brazilian east coast. The research involves geospatial analysis, field sampling, and modelling.
