“…there are a number of technical problems with such data on shoreline change, which justifies a cautious approach (for a review of these, see Baily and Nowell 1996), although they might be all that is available. the natural fluctuation of beaches, described above, also underlines the need for a cautious approach to maps or photographs that record one point in time within a constantly changing situation.…”

“…On the other hand, the human activities involve changes in the environment, sometimes expressed as modification at landscape levels, including land reclamation, recreation, land use practices and construction. The magnitude of these activities and their effects are related to urban growth, and therefore urban development must be seen as a part of the ecological system (Bailly and Nowell 1996;Bedford 1999;Ji et al 2001;Jackson et al 2001;Ruiz-Luna and Berlanga-Robles 2003).…”

Coastline mapping and coastline change detection are critical issues for safe navigation, coastal resource management, coastal environmental protection, and sustainable coastal development and planning. Changes in the shape of coastline may fundamentally affect the environment of the coastal zone. This may be caused by natural processes and/or human activities. Over the past 30 years, the coastal sites in Turkey have been under an intensive restraint associated with a population press due to the internal and external touristic demand. In addition, urbanization on the filled up areas, settlements, and the highways constructed to overcome the traffic problems and the other applications in the coastal region clearly confirm an intensive restraint. Aerial photos with medium spatial resolution and high resolution satellite imagery are ideal data sources for mapping coastal land use and monitoring their changes for a large area. This study introduces an efficient method to monitor coastline and coastal land use changes using time series aerial photos (1973 and 2002) and satellite imagery (2005) covering the same geographical area. Results show the effectiveness of the use of digital photogrammetry and remote sensing data on monitoring large area of coastal land use status. This study also showed that over 161 ha areas were filled up in the research area and along the coastal land 12.2 ha of coastal erosion is determined for the period of 1973 to 2005. Consequently, monitoring of coastal land use is thus necessary for coastal area planning in order to protecting the coastal areas from climate changes and other coastal processes.

“…Like the entire coastal region, it is characterized as an environment susceptible to human activity and alteration. The increase/decrease in precipitation resulting from natural climatic variations (Baily and Nowell, 1996;Morton et al, 2000), for example the El Niño-Southern Oscillation (ENSO) phenomenon, is also a cause of changes to regional coastal morphology. Climate change is intensifying the modes of climate variation, and one of the consequences is the alteration of precipitation patterns around the world (Barry and Chorley, 2012).…”

A B S T R A C TThe interaction between ocean, continent and atmosphere submits the beaches to intense sedimentary dynamics. All processes of transport, erosion and sedimentary deposition are under direct influence of the climate and its variability. This papper expound variations in geoindicators by remote sensing in three different sectors of the Rio Grande do Sul Coastal Plain during periods of precipitation anomalies (PP) associated with the Southern Annular Mode (SAM) and El Niño -Southern Oscillation (ENSO), by the MEI index. Data from the satellite TRMM were used between 1998 and 2013, correlated to the two indexes by classification matrices and t student test. Geoindicators were compared between periods of precipitation above and below average. The results show a negative correlation between PP anomalies on the central and south coast and the SAM, and a positive correlation between PP anomalies on the south coast and the MEI. No similar correlations are found between the north coast and either of the two indexes. The majority of events are PP (78%) and can be simultaneously related to a SAM+ and a MEI-or only MEI+. All PP+ events were concomitant with MEI+. The geoindicators presented observable variations by remote sensing between the below and above average rainfall periods. The greater number of PP events in the areas of the geoindicators studied may represent a lower volume of sediments transported from the backshore to the shoreline changing the sedimentary budget. Wind can transport dry sands from dune fields and fill lakes and lagoons of the study area, unbalancing the ecosystem.
