Caracterização sedimentológica, morfológica e vulnerabilidade ambiental da Praia do Futuro Município de Fortaleza - Ceará

Abstract

The growing urbani7ation in areas dose to a coast has provoked numerous environmental impacts that affect the natural dynamics and the balance of the beaches of directly or indirectly. The study carried out on the beach of the future, city of Fortaleza-Ceará in the months february to june, presents the results as regards the characteristics sedimentation, morphological and the degree of vulnerability in the area. The quotation studied are underlined the problems related to the use and haphazard occupation the sector of post-beah. The methodology used in this work consists of boosting morfodinâmico and hydrodynamic, sedimentológica sampling and laboratory work. The results of the study morfodinâmico present different degrees of erosion and sedimentation over the profiles topographical. The study hydrodynamic shows difference in wave height, period and current speed, there is no change in the direction of flow. The sedimentology classifies grains in sand average for the sectors of post-beach and bachface, and fine sand for the sector of shoreface. The filme sectors present degree of selection moderately selectee. The degree of vulnerability is a different manner in sectors studied.
