Thesis on coastal erosion in the caribbean

coastal morphology

On the other hand, it is a contribution to the geological knowledge of the Geotectonic Province of Santa Marta GPSM and promotes research regarding the shoreline and the effect of increasing marine activity and population, the strengthening of tourism industry in the study area and a series of geological evolutionary processes reflecting on the coastal morphology.

On the other hand, it is a contribution to the geological knowledge of the Geotectonic Province of Santa Marta and emerges as an alternative solution to various problems.

Among the recommendation is the need to recognize that sustainable management of erosive coastlines requires continuous data collection so that informed decisions can be made prior and subsequent to any mitigation strategy along with an inclusive Integrated Coastal Zone Management ICZM.

evidence of coastal erosion

The coast provides significant benefits for the national industry given the variety of unique ecosystems it has, but the implemention of ambitious development plans introduce major modifications that affect the coastal area.

Figure 1 Regional setting. This study highlights the issues associated with a "one-size fits all" approach in beach preservation and management.

Whilst these coastal mitigation structures work well on the sheltered western coast of the island, on the high energy and exposed east coast, they do so with much less success.

Metamorphic rocks are the predominant lithology, represented by locally calcareous chlorite, seri-cite and graphite phyllites, and micaceous, actinolite and talc schists and minor graphite schists of Paleogene age, which reached the greenschist facies.

Methods This study started with a compilation and analysis of existing geological data, geomorphology, climatology, hydrography, oceanographic processes waves, currents, tides , geological mappings, aerial photographs, land use, zoning plans, action plans by corporations involved in the area, as well as information from the authorities and beneficiary population within the study area, among others. However, the tectonic setting of the coast and the rate of sea level rise can also be important factors to consider. Coastal erosion represents a serious socioeconomic problem at the local level, as it affects the residents of coastal towns and the tourism industry, but also at the regional level, influencing potential regional progress due to significant economic losses, social problems and ecological damage Aiello, et al. The stability of coastal areas depends on a number of interrelated factors, which have to do with the physical aspects of their configuration and design, and with the dynamic agents acting on them. It was found that while beaches on the north coast are less prone to erosion, high erosion rates along sections of the east, south and west coasts prompted the construction of hard engineering coastline protection in the form of revetments and sea walls. In , the Institute of Marine Affairs, commenced a national shoreline monitoring programme, to bridge the science-policy nexus, by guiding formulation of policy for sustainable coastal management. Jurassic plutons and volcanites intrude and cover these metamorphic rocks. Coastal landforms are a consequence of the simultaneous operation of erosion, transportation and deposition processes and have evolved over a geologically short time, with several of them being almost exclusively the result of the action of ocean waves. Among the recommendation is the need to recognize that sustainable management of erosive coastlines requires continuous data collection so that informed decisions can be made prior and subsequent to any mitigation strategy along with an inclusive Integrated Coastal Zone Management ICZM. Coastal landforms are valuable environmental, aesthetic, and recreational resources that are subject to natural processes as well as to the effects of human activities. The world's most spectacular and dramatic erosional landforms are due to wave action, whereas the reduction of wave energy created deposition landforms. We mapped geological and physical aspects geomorphology to identify and characterize the main lithological and geomorphological units in low-lying coastal areas and rocky coastal relief especially in the coastal landforms product of deposition and erosion processes. We conducted a general survey of the area after sectioning it to study the outcrops. Metamorphic rocks belonging to the Gaira and Taganga groups, igneous rocks of the Santa Marta Batholith and a series of beach deposits occur in the study area.
