Abstract

The capacity of mangroves to reduce coastal flood risk resulted in legislation for mandatory widths of mangrove greenbelts in several countries with mangrove presence. Prescribed forest widths vary between 50 and 200 m. Here, we performed 216,000 numerical model runs informed by realistic conditions to quantify confidence in wave reduction capacity of mangroves for wind and swell waves. This analysis highlights that tidal flat areas fronting mangrove forests already account for 70% of reduction in wave heights. Within mangrove forests that are below 500 m wide, wave dissipation is strongly dependent on local water levels, wave characteristics and forest density. For forest widths of over 500 m, which constitute 46% of global coastal mangroves, around 75% or more of the incoming wave energy is dissipated. Hence, for relying on mangroves to dampen shorter waves, a new standard should be adopted that strives for mangrove widths of 500 m or more.

量化红树林对波浪衰减的不确定性,为沿海绿化带政策提供信息。
红树林减少沿海洪水风险的能力导致一些有红树林的国家立法规定了红树林绿地的强制性宽度。规定的森林宽度在50至200米之间变化。在这里,我们进行了216,000次数值模型运行,根据实际情况,量化了红树林对风和涌浪的减波能力的信心。这一分析强调,红树林前的潮滩地区已经占到波浪高度下降的70%。在宽度小于500米的红树林中,波浪耗散在很大程度上取决于当地的水位、波浪特征和森林密度。对于宽度超过500米的森林(占全球沿海红树林的46%),大约75%或更多的入射波能被消散。因此,为了依靠红树林来抑制短波,应该采用一个新的标准,争取红树林的宽度达到500米或更大。
