摘要

沿海社区容易受到风暴潮和海啸造成的极端洪水的影响。特别是被淹没的地面水流对低洼地区产生不利影响。因此,缓解措施对于保护人类生命和基础设施至关重要。迄今为止,硬结构(灰色结构)已被广泛用于保护沿海社区免受严重洪水的侵害。最近,自然和基于自然的特征(NNBF,绿色结构)也被研究用于减轻洪水灾害,如红树林(Tomiczek等人,2020),沙丘,珊瑚礁等。然而,灰色和绿色结构在防洪减力中的相互比较研究还没有得到充分的研究。因此,本研究对灰色和绿色结构在洪水水动力和建筑物受力方面的物理和数值模型进行了比较。

AN INTER-COMPARISON STUDY OF GREEN AND GRAY STRUCTURE EFFECTS ON OVERLAND FLOW FLOODING AND FORCE ON COASTAL BUILDINGS
Coastal communities have been prone to extreme inundations generated by storm surges and tsunamis. Especially inundated overland flows adversely impact low-lying areas. Therefore, mitigation solutions are essential in protecting human lives and infrastructures. So far, hard structures (gray structures) have been widely used to protect coastal communities against severe flooding. Recently, Natural and Nature-Based Features (NNBF, green structures) also have been studied for flood hazard mitigation, such as mangroves (Tomiczek et al., 2020), dunes, reefs, etc. However, the inter-comparison studies of gray and green structures in the flooding and force reduction have not been investigated sufficiently. Therefore, the present study investigated the physical and numerical model comparison of gray and green structures regarding flooding hydrodynamics and forces on the buildings.
