Caracterização morfológica e sedimentar da praia de Zalala-Quelimane

Abstract

Zalala Beach is a sensitive environment, is presenting morphological variations that can scare off ides sunbathers of various points of Zambézia province, other parts of the country and the world. Thus it is important understand the morphological and sedimentology of the beach, so that there is better planning and targeting of coastal protection. The aim of this study was to examine the spatial and temporal variation of granulometric parameters through statistical parameters (diameter-medium, asymmetry, kurtosis, and standard deviation) and morphology through topographic profiles along the Intertidal zone (ZI). For the accomplishment of this work have been established 9 topographic profiles from the dunes to the low level of the tide of syzygy. Over the profiles, sediment samples were collected in the month of March (rainy season) and in July (dry season). The results show that the seasonal variations of the coastal processes control the morphology of the beach and the seasonal behavior of the sediments.
