无论是面积还是人口，珠江三角洲都是世界上最大的城市区域。这是一个低洼易发洪水的沿海环境，容易受到海平面上升(SLR)和台风造成的极端水位的影响。一个有限体积社区海洋模式在南中国海和珠江三角洲的实施被用来理解未来单反、潮汐和台风风暴潮将如何相互作用和影响沿海洪水。SLR信号和极端潮汐水位是造成洪水的主要原因；然而，对于2.1米SLR，潮汐放大可能超过0.5米，在规划未来的海岸防御时应予以考虑。另一方面，如果未来发生像Hato或Mangkhut这样的台风，这是袭击该地区的最新和最强的台风，预计沿海地区的涌浪水位将降低至多0.5米。
The Pearl River Delta contains the world's largest urban area in both size and population. It is a low‐lying flood‐prone coastal environment exposed to sea level rise (SLR) and extreme water levels caused by typhoons. A Finite Volume Community Ocean Model implementation for the South China Sea and the Pearl River Delta is used to understand how future SLR, tides, and typhoon storm surges will interact and affect coastal inundation. The SLR signal and extreme surge levels provide the major contributions to flooding; however, amplification of tides could exceed 0.5 m for 2.1 m SLR and should be considered when planning future coastal defences. On the other hand, if typhoons like Hato or Mangkhut, the latest and strongest ones hitting the area, were to happen in the future, a surge level reduction up to 0.5 m could be expected in coastal areas.
