项目摘要

Coastal areas are dynamic and fast changing natural environments. Several factors, acting on different time scales control their evolution. Furthermore, coastal areas are densely populated, especially in the Sultanate of Oman where more than half of the population is living at the coast. Due to economic improvements Oman experiences substantial changes in land utilization, particularly In Al Batinah and Muscat regions. With the given natural boundary conditions different interests of various user groups are in conflict. Ongoing global climate warming will result in further intensification of the situation. In general there is a close link between the environment and sustainable economical development. Geological research in coastal areas as proposed here, yields scientific information to form the base of an integrated coastal zone management system, enabling the sustainable development for the welfare of the society.Coastal evolution is a function of several forcing factors e.g.: differential land movement which in turn is an effect of local variations in the tectonic stress field; climate and sediment availability. We plan to quantify the various forcing factors by analysing Quaternary coastal sediments and geomorphologic features (e.g. terraces, notches) as archives and indicators. This proposal focuses on revealing long-term and short term changes within the coastal zone. Long-term changes can be described by the reconstruction and comparison of the relative sea-level development along the coastline. Short-term coastal changes are often related to natural hazards. Tropical cyclones as well as tsunamis are known to have affected Oman s coastline in the past. By analysing geological archives information regarding recurrence intervals and potential damages will be revealed which allows assessing the risk and estimating the vulnerability. This will be done for different areas along the coast which have been identified as key-locations. Sediment cores and ground-penetrating radar (GPR) surveys are proposed to analyse Quaternary coastal sediments; terrestrial Light Detection and Radar (T-LIDAR) techniques will be used to analyse geomorphologic features (e.g. terraces, notches).The proposed study will be carried out by a research team involving B.Sc. and M.Sc. students.

沿海地区是动态和快速变化的自然环境。以不同时间尺度作用的几个因素控制着它们的演变。此外，沿海地区人口稠密，尤其是在阿曼的苏丹国，那里有超过一半的人口居住在沿海地区。由于经济改善，阿曼经历了土地利用的实质变化，尤其是在Al Batinah和马斯喀特地区。在给定的自然边界条件下，各种用户群体的不同兴趣正在发生冲突。持续的全球气候变暖将导致情况进一步加剧。通常，环境与可持续经济发展之间存在密切的联系。按照此处提议的沿海地区的地质研究产生科学信息，以形成沿海地区综合的沿海地区管理系统的基础，从而使社会福利的可持续发展成为可持续发展。CoastalEvolution是多种迫使因素的函数，例如：差异地土地运动，这反过来反过来又是构造压力领域局部变体的效果；气候和沉积物的可用性。我们计划通过分析第四纪沿海沉积物和地貌特征（例如露台，凹口）作为档案和指标来量化各种强制因子。该提案着重于揭示沿海地区内的长期和短期变化。长期变化可以通过对海岸线的相对海平面发展的重建和比较来描述。短期沿海变化通常与自然危害有关。众所周知，热带气旋和海啸过去曾影响阿曼的海岸线。通过分析有关复发间隔和潜在损害赔偿的地质档案信息的信息，该信息允许评估风险并估算脆弱性。这将针对已被确定为关键位置的沿海不同地区进行。提出了建议分析第四纪沿海沉积物的沉积物核心和地面穿透雷达（GPR）调查。陆生光检测和雷达（T-LIDAR）技术将用于分析地貌特征（例如露台，凹口）。拟议的研究将由涉及B.Sc.的研究团队进行。和硕士学生。
