Marine Ecology and Invasive Species

The hydrodynamic study of the littoral sector between Cumbuco and Matões, NW coast of Ceará Sstate, was carried out through an empirical method that makes use of a graph-based refraction diagram associated with fi eld work.This procedure has also considered the the coastal geometry infl uence on geomorphogenesis processes, where wind and waves exert a fundamental role.Modelling of the intensity and direction of the longshore transport has shown that the prevailing direction is SE-SW and its intensity is changeable in the various costal sectors.This approach led to the development of a concept model which deals with a spiral-shaped coast geometry, mostly considering the potential sediment littoral drift, whose empiric results could be associated with fi eld observations evidenced as erosive and/or depositional processes.
