The project focusses on coast-geomorphological analyses in Oman. On the one hand, long-term changes are relevant. These are seen as a consequence of global eustatic changes as well as local neotectonic-isostatically driven movements. Observable along the coastline of Oman are terraces which formed as wave-cut platforms and were elevated thereafter. Preliminary results of a reconnaissance survey proofed Quaternary ages of terraces formation. The aim of the project is to quantify the uplift rates and decipher the responsible driving forces. The hypothesis is that a combination of the plate tectonic configuration (convergence of Arabian with Eurasian plate) as well as local isostatic factors (serpentinisation of ophiolitic rocks) is responsible for the observed deformation pattern. Short-term changes are the second focus of this proposal. Coastal deposits, seen as evidence for extreme wave events will be analysed. Both, storm surges as well as tsunami are known to have impacted the coastline in the past. The project is based on field work. High-resolution methods will be used besides geological mapping. Terrestrial laser scanning techniques, differential GPS, ground-penetrating radar as well as analyses of arial photography will be applied.

该项目的重点是阿曼的海岸地貌分析。一方面，长期变化是相关的。这些被视为全球海平面变化以及局部新构造均衡驱动运动的结果。沿着阿曼海岸线可以观察到形成为波浪切割平台并随后升高的阶地。勘察的初步结果证实了梯田形成的第四纪时代。该项目的目的是量化上升率并破译负责任的驱动力。假设是板块构造构造（阿拉伯板块与欧亚板块的聚合）以及局部均衡因素（蛇绿岩的蛇纹石化）的组合导致了观察到的变形模式。短期变化是该提案的第二个重点。将分析被视为极端波浪事件证据的沿海沉积物。众所周知，风暴潮和海啸过去都曾影响过海岸线。该项目基于实地工作。除了地质测绘之外，还将使用高分辨率方法。将应用地面激光扫描技术、差分GPS、探地雷达以及航空摄影分析。
