Abstract

This article presents an investigation of the gravity hill phenomena by analysing its geospatial data. Wadi Al Baida located in Al Madinah, Saudi Arabia has been taken as a case study. Wadi Al Baida is listed as one of the sites in the world where the said phenomena exists, but the site has been famous for any sort of magnetic force because the vehicles move uphill and on flat road without any engine power on. The topography of the valley is studied by using the geospatial data of the area and by creating Digital Elevation Models (DEMs) based on Point Kriging method of gridding. The results show that the area has natural slope and there is a significant difference in the elevations of the start and the end point of the valley. A longitudinal profile is also generated to validate the results obtained by DEMs and it is found that the road has an average slope of 2.6% which makes the vehicles and rolling objects move on their own due to the force of gravity. Also, the concept of gravity hill has been explained with the help of a diagram which is easy to understand by the readers.
