针对沿海城市环境，提出了一种风暴潮引发洪水的模拟方法，称为基于gis的细分再分配（GISSR）方法。该方法将GIS与曼宁方程相结合，计算进入所考虑的地理区域的水量，然后将其适当地重新分配到该区域。它使用风暴潮高度和海岸线潮汐的时间历史作为输入。它能够在海岸线上结合各种保护措施，例如海堤。在未来的洪水模拟中，考虑一个规定的海平面上升值是很简单的。从计算的角度来看，与GeoClaw或ADCIRC等现有的洪水模拟工具相比，GISSR方法非常有效，由于其物理模型的潜在复杂性，这些工具的计算时间要多出几个数量级。通过将其结果与飓风桑迪在纽约市观测到的实际洪水范围进行比较，发现该方法具有很高的准确性。几个例子展示了它的能力，涉及纽约市曼哈顿下城的不同保护措施。GISSR方法是确定沿海城市最优防护策略的理想方法，因为其计算效率高，因为优化需要非常大量的洪水模拟。
A storm surge–induced flood simulation methodology, called the GIS-based subdivision-redistribution (GISSR) methodology, is proposed for coastal urban environments. The methodology combines GIS with Manning’s equation to calculate the volume of water flowing into the geographical area under consideration and then redistributes it appropriately over that area. It uses as input the time histories of the storm surge height and of tides along the coastline. It is capable of incorporating a variety of protective measures along the coastline, such as seawalls. For flood simulations in the future, it is straightforward to account for a prescribed value of sea level rise. The GISSR methodology is extremely efficient, from a computational point of view, compared to existing flood simulation tools, such as GeoClaw or ADCIRC, which take several orders of magnitude more computing time because of the underlying complexity of their physical models. The methodology is found to be highly accurate by comparing its results to the actual extent of flooding observed during Hurricane Sandy in New York City (NYC). Several examples demonstrating its capabilities are provided involving different protective measures in NYC’s Lower Manhattan. The GISSR methodology is ideal for determining the optimal protective strategy for a coastal city because of its high computational efficiency since optimization requires a very large number of flood simulations.
