Alongshore variations of beach configuration along the Tróia-Sines embayed coas...
Gama, Cristina; Albareiro, Luís; Baptista, Paulo; Marques da Silva, RafaelAerial photography of 1996 and 2001 coupled with DSAS extension for ArcGIS 9.x.The field data obtained by DGPS monitoring prototype system in 2009 were also to study the alongshore variations of beach configuration along 65km of the Tróia-Sines embayed coast (TSEC, SW Portugal). The results obtained show that the TSEC is characterized by the southward increase of the beach width, inner backshore height and seaw...
Beachface and berm morphodynamics on a steep beach: Melides beach, Southwest Po...
Gama, Cristina; Baptista, Paulo; Marques da Silva, Rafael; Pinheiro, IsabelThe Melides beach, a sector of the Tróia-Sines Embayed Coast with 2.5km long, corresponds to a steep beach exposed to high-wave energy, with rapid erosion and accretion cycles related to winter storm incidence. The alongshore and cross-shore beach volume and width variability of the Melides beach were studied in detail using a survey methodology based on DGPS (Global Positioning System in Differential mode) and...
