直接模拟发达城市地区的洪水比在许多海啸研究中使用粗糙度的更常见的裸露地球模拟提出了更大的挑战。本研究在日本和歌山开南详细的地形模型上，用实验室结果比较了四种海啸淹没长波模型的性能。所有的模拟包括建筑物，这对陆上洪水传播有很大的影响。模型间的比较产生了几个明显的特征：（1）在总是湿润的地区，模型间的变化很小;（2）湿润、干燥和陆上传播增加了模型间在洪水前锋到达时间、最大水面高程和陆上流速方面的变化;（3）淹没面积和最大水面高程的模型间变异（V）小于淹没锋流速和最大流速。V的来源似乎发生在润湿，干燥和详细的代码实现的差异，而不是模型物理的主要差异。使用已发表的海啸脆弱性模型，Vlead显着差异的预测损害。差异最大的脆弱性，使用速度和较低的脆弱性，只使用最大淹没深度。根据这些结果，淹没区和水位从建筑物解决模拟可能会被分配相对较高的置信度，所有的预测速度应被认为有更大的误差，并可能应考虑只有当使用合奏。
The direct simulation of inundation in developed urban areas presents a much greater challenge than the more common bare earth simulations that use roughness, which are used in many tsunami studies. This study intercompares the performance of four longwave models for tsunami inundation on a detailed topographical model of Kainan, Wakayama, Japan, with laboratory results. All simulations include buildings, which have a large impact on overland flood propagation. Inter-model comparisons yield several apparent characteristics: (1) variations between models were small in areas that are always wet; (2) wetting, drying, and overland propagation increased inter-model variation in the inundation front arrival time, maximum water surface elevation, and overland flow velocities; (3) inundated areas and maximum water surface elevations show lower inter-model variation (V) than inundation front velocity and maximum current velocities. Sources forVappeared to occur from differences in wetting, drying, and detailed code implementation rather than major differences in model physics. Using published tsunami fragility models,Vled to significant differences in the predicted damage. Differences were largest for fragilities that used velocity and lower for fragilities that only used maximum inundation depths. Based on these results, inundated areas and water levels from building-resolving simulations might be assigned relatively higher confidence, and all the predicted velocities should be considered to have a greater error and potentially should be considered only when using ensembles.
