Description:
The studies areas lay in Hurghada region include different aspects of coastal development. It represents different environmental problems and threats to the Red Sea ecosystem and geosystem. They include two tourist projects, a central marina for yachts and fishermen and a site for oil exploration and production. All sits have implemented Environmental Impact Assessment studies (EIA). Unfortunately, dredging and landfilling caused severe coast destruction and shoreline change in these areas. All sites have accurately surveyed and environmental problems cited, oceanographic parameters were measured, and 109 samples were collected from the beach and the tidal flat of four sits forming the study area. Grain size, carbonates and organic matter contents, major and trace
elements were determined. Cluster analysis and correlations were carried out. The results reflect the impact of coast destruction and shoreline change. Grain size analysis indicated the predominance of coarse grained sediments close to the landfilled areas. Mixtures of terrigenous and biogenic fragments are the main components of these sediments. The distribution of carbonates supports this result where carbonates content is low in the beach area and gradually increases seaward. Fine sands and mud dominate the dredging areas and cover the nearby corals and bottom facies. Results of major and trace elements, total organic matter (TOM), organic carbon (OC), and carbonate contents were used to discuss the sediment characteristics and interpret the abundance of some parameters in the impacted areas. The findings of this study help decision makers to identify anthropogenic impacts and better assess of the needs for remediation.
