| Summary: | In flight operations, safety is always a major concern. Incidents and accidents often occur during the takeoff and landing phases, and one of the most influential factors contributing to incidents and accidents is runway condition. In rainy weather, a layer of water film can form on the runway surface which in turn reduces friction between the aircraft tires and the runway surface. Therefore, it is critical for pilots about to commence takeoff or landing procedure to receive information regarding the depth of water on the runway. Currently, this process is done by performing measurements on areas with water accumulation.
Today there are several empirical and analytical methods that are commonly used to predict the depth of the water layer on highways. However, the existing models have some limitations and have not been widely used in aviation. An alternative method is needed to overcome this problem. In this study, a simulation of water flow on the runway surface will be carried out using a GIS (Geographic Information System) software. The program will simulate 2-dimensional shallow water flow on the runway, which is mathematically described by the Saint Venant equation. The equation is solved numerically using Green’s function Monte Carlo method.
The results obtained from the simulation are in the form of a raster data that shows the water depth and discharge at certain timesteps. From these results the Location where water is accumulated and the drainage capacity required by the runway can be determined. |
