The researchers studied a landslide in the Three Gorges Reservoir area to understand how rainfall and reservoir water levels affect its stability. They used GPS data and a computer model to analyze the landslide's behavior from 2004 to 2009. They found that the landslide moved faster after the reservoir was filled and slowed down during rainy seasons. The stability of the landslide was closely linked to changes in rainfall and reservoir levels, making it more likely to react to these factors. This study can help assess landslide risks in similar geological conditions.
