Slope failure is a serious geologic hazard in many countries in the world including Malaysia. In order to prevent slope failure, the hazardous symptoms can be detected early in slope monitoring process. Nowadays, slope failure symptoms monitoring has been done by human by on site observation at the slope spot and it is dangerous for the human safety. Furthermore, it takes longer time to complete the investigation and some of the data collected are inaccurate because human view is limited. Therefore, this project is to evaluate the performances of Unmanned Aerial Vehicle (UAV) to monitor the slope condition. A slope at Taman Harmoni Vista at Pagoh, Johor has been selected as a study area. The measurement of slope studied was 150 meters in length and 20 meters in height respectively. The aim of this project is to evaluate the performances of Unmanned Aerial Vehicle (UAV) to monitor the risk slope. Visual image of 3D modelling was obtained from Pix4D Mapper and Global Mapper software was used to analyze the slope failure symptoms. There are defects that have been identified from 3D modelling of the slope which is tension crack on slope and surface crack on the drainage. The use of UAV is an alternative method to obtain quality picture and 3D model for inspection of the slope. This method expected to facilitate the work of inspection slopes in addition to saving time, energy and cost as well asreducing the risk of harm.
