Investigations in the field of coastal and marine geology within the joint German-Vietnamese project aim at the spatial-temporal reconstruction of the hitherto only sparsely known coastal evolution in SE-Vietnam during the Holocene period. Main tasks are (i) recording and analysing major sediment-bodies and sediment surfaces to reveal (ii) depositional patterns and stratigraphic architecture; and (iii) the principal hydrodynamic and sediment-dynamic processes in the coastal and shelf zone; (iv) evaluating and balancing the terrigenous sediment input; and (v) investigating the magnitude and influence of short and longer term sea-level fluctuations and coastline migration. The results are expected to provide principal knowledge of the geologic history and evolution of the SE-Vienamese coastal zone over the last 10000 years. In addition, these results should support planning strategies for integrated coastal zone management with respect to sustainable development. Reference should be given to competing interests between potential users of the coastal zone e.g. tourism, fisheries, exploitation of mineral resources.

在德国-越南联合项目中，沿海和海洋地质领域的调查旨在对越南东南部全新世期间迄今为止唯一鲜为人知的海岸演变进行时空重建。主要任务是(1)记录和分析主要沉积物体和沉积物表面，以揭示(2)沉积模式和地层结构；（三）沿海和陆架区的主要水动力和沉积动力过程；评估和平衡陆源泥沙输入；（五）调查短期和长期海平面波动和海岸线迁移的幅度和影响。这些结果有望提供关于越南沿海地区过去1万年的地质历史和演化的主要知识。此外，这些结果应支持与可持续发展有关的沿海地区综合管理规划战略。应考虑到沿海地区潜在使用者之间的竞争利益，例如旅游、渔业、矿产资源的开采。
