ABSTRACT: The aim of this work was to analyze the sedimentary record coastal plain Pelotas Basin, placing it in context temporal and spatial scales, proposing a stratigraphic hierarchical framework. plain, located southern Brazil northern Uruguay, is mainly formed by four Quaternary barrier-lagoon systems. Three these systems were studied through integration surface subsurface data (geomorphological topographical mapping, outcrops description, geoprocessing, dating Ground Penetrating Radar -...
Many prograded barriers and some dunefields in theworld have been termed 'beach ridge' plains, but the actual genesis of 'ridges' is often unknown. Use terms, berms, beach ridges foredunes also confusing literature because their definitions are highly variable commonly used interchangeably. Thus, formation definition sand briefly reviewed. Beach re-defined as entirely wave formed deposits which most during high conditions and/or elevated water levels (e.g. storm surges). Foredunes by aeolian...
This paper focuses on high-resolution coastal stratigraphy data, which were revealed by the Ground Penetrating Radar (GPR) system. Surveys performed with GPR surface of prograded barriers reveal patterns reflections that allow interpretation geometry and deposits in a continuous mode. At Curumim barrier southern Brazil (29°30′ S–49°53′ W), two-dimensional transverse survey revealed, high precision, serial contacts between aeolian relict foredunes beach have strong correlation sea level. In 4...
The sedimentary deposits and geomorphic features preserved in the Rio Grande do Sul coastal plain, southern Brazil, represent a significant record of late Quaternary climatic changes with its associated glacio-eustatic sea-level fluctuations. sediments plain belong to two major depositional systems - an alluvial fan system developed along inner part barrier-lagoon complex four distinctive transgressive-regressive cycles seaward. were derived from igneous metamorphic rocks Precambrian shield...
Abstract The Holocene barrier along the southern Brazilian coast is most likely continuous structure in world. This characterized by a extending for 760 km, interrupted only six discontinuities, which are associated with narrow lagoonal inlets and river mouths. marked huge availability of sand, gently sloping continental shelf, incident waves moderate to high energy. Together, these factors constitute ideal conditions formation coastal barriers. During periods low sea-levels, shelf front La...

Evidences of coastal erosion in Rio Grande do Sul have been obtained by three methods: (a) analysis the long-term morphodynamics and stratigraphy barriers, (b) annual shoreline mapping using Differential Global Positioning System (DGPS), (c) local beach profile measurements. The first method reflects as continuity geological evolution last 5 ka, taking place mainly along southern half gentle projections. second represents a shorter temporal scale indicates that approximately 80% coast is...
Abstract This paper examines patterns of foredune vegetation along an embayment in southern Brazil and the relationships between variations percent cover diversity, environmental factors such as beach/surfzone type exposure to wind wave energy. The study was conducted on Moçambique Beach, Brazil, which displays significant alongshore prevailing winds waves, morphodynamic type, dimensions dune systems diversity. Two surveys were carried out contiguous 1 m 2 quadrats across foredune....
Rio Grande do Sul is the southernmost state in Brazil. Open sandy beaches dominate 630-km long shoreline that 76% still undeveloped. Less than 5% of state's population (totalling 9.7 million people) live coastal cities. However, growing faster average since 1990. Although intense erosion widely accepted along Conceição lighthouse and Hermenegildo, extent a controversial issue. Discussions arise from contrasting results presented by studies addressing Sul. Recent DGPS monitoring indicates...
