Bittencourt Multidisciplinaria (Ciencias Naturales y Exactas) coral reefs longshore drift sediment deficit Northeast Brazil This paper shows that the location of the shoreface bank reefs along the northeastern and eastern coasts of Brazil, in afirst order approximation, seem to be controlled by the deficit of sediment in the coastal system. The sediment transportpattern defined by a numerical modeling of wave refraction diagrams, representing circa 2000 km of the northeasternand eastern coasts of Brazil, permitted the regional-scale reproduction of several drift cells of net longshore sedimenttransport. Those drift cells can reasonably explain the coastal sections that present sediment surplus or sediment deficit,which correspond, respectively, to regions where there is deposition and erosion or little/no deposition of sand. Thesediment deficit allows the exposure and maintenance of rocky substrates to be free of sediment, a favorable conditionfor the fixation and development of coral larvae. 2008 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32780115 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.1 Vol.80 |
