Human settlements in coastal areas are highly vulnerable to extreme events, especially in the Mediterranean area, which houses a large number of tourists during the summer and autumn months. It is important to carry out hazard studies at local scale to improve our understanding of natural and anthropogenic processes involved in episodes of coastal flooding. We reconstruct and characterize an extreme weather event in Tossa de Mar (northeastern Spain) and the subsequent urban flooding that occurred in 2008. Our results show flood heights up to 1.27 m, with the maximum occurring between 24 and 64 h after the start of the event. This is broadly consistent with the reconstructions obtained through interviews and photographs. Based on model simulations, we produce a hazard map for the town based on hydrodynamic scenarios for different return periods. We show that the southern part of the town is more susceptible to flooding, whereas the northern part is relatively resilient to extreme events. We recommend the adaption of a currently existing dune by adding vegetation and slightly increasing its height. This low economic cost action would significantly reduce flooding and increase resilience in this area.

沿海地区的人类住区极易受到极端事件的影响，尤其是在夏季和秋季有大量游客的地中海地区。重要的是在当地范围内进行灾害研究，以提高我们对沿海洪水事件中涉及的自然和人为过程的理解。我们重建并描述了托萨德马尔（西班牙东北部）的极端天气事件以及随后发生在 2008 年的城市洪水。我们的结果显示洪水高度高达 1.27 m，最大值发生在洪水开始后的 24 到 64 小时之间。事件。这与通过采访和照片获得的重建大致一致。在模型模拟的基础上，我们根据不同重现期的水动力情景为该镇制作了一张危险地图。我们表明，该镇的南部更容易受到洪水的影响，而北部对极端事件的抵御能力相对较强。我们建议通过添加植被并稍微增加其高度来适应当前存在的沙丘。这种低经济成本的行动将显着减少洪水并提高该地区的复原力。
