N2 - Landslides often occur during or shortly after heavy rains in several locations. One of the preventive efforts proposed is the removal of groundwater levels from the subsurface. A method proven to be effective in achieving this is the application of horizontal drain to increase the safety factor on a slope against landslides, especially during the rainy season. This research was, therefore, conducted to summarize the results of previous studies both on a field scale and numerical analysis to determine the effectiveness of horizontal drain on landslides. The results showed the horizontal drain has the ability to effectively lower the groundwater level at different degrees depending on soil parameters, rain conditions, the topography of the area, and the dimensions used. Moreover, the horizontal drain was also able to increase the slope safety factor by 1–4% for 1-m groundwater level decrease and al-most 20% for 9-m groundwater level decrease.
