Estudo da morfodinâmica sedimentar na praia de Wimbi na província de Cabo Delgado 2006 - 2018

Abstract

This work aimed to study the sedimentary morphodynamics in Wimbi beach. For this development an inquiry was elaborated where in its turn were inquired 20 frequent attendees composed by: local traders, bathers and sportsman The questions of the questionnaire were of the type: its age, years that frequent the beach, if on this beach there have been drowning phenomena and which people are affected. The results obtained indicated that 50% of the drowning cases on this beach have to do with and diving problems and the most affected are the children, and when the preventive measures suggested that markers or signposts should be fixed where the limit of the shallow areas. As for the type of sediment found in this beach, it was mostly very coarse-grained with 96%, and the morphology of this beach has a very sharp ingrimity and may vary greatly in its topography in the rainy season due to the sea grass clustering coastal zone. Evaluated the shoreline progradation on this beach has been advancing and the following year a shoreline retraction, that is as one year the shoreline advances the next year it has to retreat and how much vulnerabilities of coastal erosion occurrences on this beach the rate of their occurrence is very low with a value of 0.4m / year over a distance of 5.47m.
