Abstract:
This study concerns the geomorphology of the coastline of the Qatar Peninsula. In all, the coastline is approximately 750kg long and is dominated by Tertiary and Quaternary limestone rocks. Since little previous work has been carried out into the coastal geomorphology of the Arabian Gulf in general and Qatar in particular, a fundamental task was to undertake a classification of the coastal types. There are: 1) sand dunes and sheets; 2) sabkhas; 3) cliffs; 4) coral reefs; 5) beaches and 6) mangroves. A second task in this study was to investigate the processes responsible for the different coastal types. This was achieved using different field and laboratory techniques. Aerial photo interpretation enabled the nature of forms to be better understood and photos of different dates enabled temporal change to be investigated. Both Abeny level and Dumpy level were used to show the forms of the different coastal types. Particle size analysis was used to differentiate the origin of sediments. Laboratory experiments of salt weathering on rocks of the Qatar shoreline indicated the effectiveness of this process. SEM analysis showed the mix of aeolian and beach transport histories in the coastal sediments. The study shows that the following factors are particularly important in producing the distinctiveness of the Qatar coastline: these are warm sea temperatures leading to rapid chemical weathering; the prevailing NW ('shamal') wind, which influences strongly sand supply at the coast and longshore drift direction; and a low tidal range.
