This project aims at creating a knowledge base for an improved understanding of the physical processes associated with the breaching of coastal barriers such as dunes under extreme storm surges as well as with those associated with the response to the subsequent inundation and recovery of freshwater aquifers after the vertical intrusion of the propagating seawater. The new knowledge and the prospective predictive formulae will be implemented in state-of-the-art surface and subsurface numerical codes, and particularly for properly coupling these codes. By these means, examining possible climate change scenarios will become feasible by developing a fully coupled surface-subsurface model system that includes previously neglected processes and interactions.

该项目旨在建立一个知识库，以便更好地了解与极端风暴潮下的沙丘等海岸屏障的冲破有关的物理过程，以及与在海水垂直入侵后对随后的淡水含水层的淹没和恢复作出反应有关的物理过程。新的知识和预期的预测公式将在最先进的地面和地下数字代码中实现，特别是为了适当地耦合这些代码。通过这些手段，通过开发一个包括以前被忽视的过程和相互作用的完全耦合的地表-地下模式系统，研究可能的气候变化情景将变得可行。
