The resulting model of sediment transport, as obtained by numerical modelling from the refraction diagrams, taking into consideration the angle of approach and waves heights along the 10-m isobath, was capable of reproducing the patterns of sediment dispersion provided by geomorphic indicators of the longshore drift. All this coastal region, approximately 900 km in length, is characterized by a significant divergence zone in the direction of net longshore drift of sediments, the potential intensity of which increases considerably in value, in almost its entire length, continuously toward downdrift, which might explain the greater or lesser long term susceptibility to erosion, during the Quaternary, along the coastal stretch studied.Submitted by Texeira Ana (atanateixeira@gmail.com) on 2012-07-31T17:44:33Z No. of bitstreams: 1 BITTENCOURT, ABÍLIO C.S.P.(4).pdf: 701104 bytes, checksum: 89b99e362db98662524e8ee8c6785241 (MD5)Made available in DSpace on 2012-07-31T17:44:33Z (GMT).
