Flooding is a major problem in the UK as recent high profile events in the summers of 2006 and 2007 have shown. In these events the damage to property and belongings ran into billions of pounds and a number of people were injured or lost their lives in these events. Therefore, predicting the location and severity of flooding is extremely important in preventing these losses. Current computer models for predicting flooding are highly accurate, but take a very long time to run even on the fastest computers. This project intends to use a technique known as cellular automata, a model based on the localised interactions of small cells, to simulate flooding in such a way that it will be possible to run complicated scenarios on a standard PC. The new approach will gain efficiency by making use of the fact that each cell can only 'see' the cells closest to it and the project will investigate the best ways of allowing each cell to communicate with its neighbours. The approach will be tested over a number of different flooding scenarios and compared with existing methodologies to demonstrate its accuracy and increased efficiency over standard methods.

洪水是英国的一个主要问题，2006年和2007年夏天最近发生的引人注目的事件表明了这一点。在这些事件中，财产和财物损失达数十亿英镑，一些人在这些事件中受伤或丧生。因此，预测洪水的位置和严重程度对于防止这些损失至关重要。目前用于预测洪水的计算机模型非常准确，但即使在最快的计算机上运行也需要很长时间。该项目打算使用一种称为细胞自动机的技术，一种基于小细胞局部相互作用的模型，以模拟洪水，从而可以在标准PC上运行复杂的场景。新方法将通过利用每个细胞只能“看到”离它最近的细胞这一事实来提高效率，该项目将研究允许每个细胞与其邻居通信的最佳方法。该方法将在许多不同的洪水情景下进行测试，并与现有方法进行比较，以证明其准确性和比标准方法更高的效率。
