Languages of publication
A disaster is a sudden, calamitous event that seriously disrupts the functioning of a community or society and causes human, material, and economic or environmental losses that exceed the community's or society's ability to cope using its own resources. All over the world the impact of disaster is very challengeable. Sri Lanka is not except for it. Landslide, flood, tsunami, drought and accidents are in abundance. Considering the Landslide, Badulla District is often affected by the landslide disaster. Thus, this study aims for this study, primary and secondary data were used. MS Excel 2013 and Arc GIS 10.4 were used to analyze the study. The findings of the study, the cause of physical factors around 40% and around 60% of causes occurred by human factors of landslide. Identify the landslide area measures the landslide, collecting the reports of infrastructure and precautions of landslide are supporting to reduce the effect. When shows the maps using GIS technologies for this landslide area helping to move the people to safe zone. Depth roots plants should be planted in this area to capture the soil and rock that will prevent the slide. Reservoirs must be built after doing the geological examination and geomorphological examination. Using the screed concrete in the base of mountains and making the Gabion walls of the width and height of mountains help to prevent the slide. This method called Geo textile. These solution helps to control the effect from landslide.
